KyTopo: Kentucky’s New Topographic Map Series

For many decades, the USGS Topographic Quadrangle Map series was “THE” base for anything mapping related. A wide array of Federal programs required that they be utilized for submittals, surveyors included them on plats as inset maps, and Kentucky-specific statutes relied on them for defining things like “blue line” streams. The “topo” or “quad” maps framed our perception of the nation’s surface and the planimetric features situated upon it.

In the mid 90s, USGS brought the topographic map into the digital age by releasing their Digital Raster Graphics (DRG) product. Finally, the basemap we’d relied on for ages was now in the background on our massive CRT monitors. For better or worse, our relationship to the maps was strengthened as we became mesmerized by the slow rendering raster image on our screens. GIS users quickly realized that the vector data they’d been creating and maintaining for years didn’t always line up perfectly with the DRGs. As a result, agencies quickly scrambled to adjust their points, lines, and polygons to the almighty map that we held as gospel. You know . . . they were made by USGS so they had to be correct!

Flash forward to December of 2011 when the Kentucky Aerial Photography and Elevation Program (KYAPED), or KyFromAbove effort, became a reality. With a focus on acquiring state-of-the-art LiDAR data and full-color, high resolution aerial photography, KyFromAbove promised a new view of the Commonwealth’s surface with a level of detail and clarity that had never been imagined. Since that time, and not surprisingly, one of the primary requests made by stakeholders in the GIS Community has been new LiDAR-derived contour lines.

In early 2017, as the impending reality of a statewide elevation model came into focus, the Kentucky Division of Geographic Information (DGI) began to investigate the creation of a statewide contour dataset and associated cartographic products and web services. Consultation with the Commonwealth’s GIS gurus prompted us to think outside of the box. Sometimes, bending the rules is necessary, even though it may lead to more complex processes and require more resources.

Although it was painful at times, going through this process was fruitful in that the KyTopo Map Series was conceived. The idea was to create a cartographic product that could be printed and shared as a cached web mapping service. Then, the primary derivative datasets (i.e. contours, hillshade, spot elevations, . . .) would be made available for download and published to the KyGeoNet. Two statewide contour datasets are slated for creation. One will be somewhat aligned with the USGS contour intervals in Kentucky (10’, 20, & 40’) and another statewide set of 5’ contours will leverage scale threshold settings and group layer functionality to adjust dynamically to the viewer’s map scale.

The KyTopo map series will be Kentucky-specific in several ways. First, an entirely new set of landscape-oriented quadrangle tiles have been developed. These new tiles align with our 5k tiling scheme and are in Kentucky’s Single Zone coordinate system rather than the traditional USGS UTM-based maps. The map area is exactly 30” wide (60,000’) by 20” tall (40,000’) and fits nicely on a standard Arch D (24” x 36”) printed page. The typical 1:24,000 (1” – 2000’) scale has been maintained and there are only 549 tiles as opposed to the 779 tiles offered by USGS. Importantly, the new tiles have square corners unlike the UTM version!

Next on the agenda was the task of coming up with names for the new map tiles. In many instances, the names from the old USGS quads were directly adopted. However, there were many cases where it just didn’t make sense. DGI staff studied the USGS methodology used to name its maps many years ago and employed that approach. Basically, the most prominent feature within a given tile was used for the name. For example, the largest city or the most centrally located place name (GNIS) was selected. In undeveloped areas, State Parks, State Forests, and natural features (i.e. streams, ridges, lakes, . . .) were used for naming the tile they dominated.

After pondering contour interval and index values, the standard USGS 10’, 20’ and 40’ intervals were embraced along with their associated 40’, 100’ and 200’ indices. Having these different interval levels is necessary due to great variance in elevation change as you move from east to west across the Commonwealth. Generally, the KyTopo intervals by tile, align fairly well with their USGS counterpart.

20’ Interval & 100’ Index
20’ Interval & 100’ Index

Weeks were spent gathering authoritative data for the project and fine tuning the map layout and symbology. Lots of thought was put into which layers should be included and which should be cast aside. As previously noted, all of the data is available in the public domain and much of it has been sourced directly from Kentucky State Government and a variety of Federal agencies. In fact, over 75% of the layers were already published to the KyGeoNet. It is anticipated that the maps will be updated on an annual basis so changes in the transportation network, forest cover, boundaries and other features can be updated accordingly.

The production hardware environment for the KyTopo project consists of one VMware-based 64-bit virtual server with 4 cores, 64GB of RAM, and 2TB of fiber-attached storage running Windows Server 2012 R2. Esri’s ArcGIS Desktop 10.3.1 and its Data Driven Pages functionality are the primary tools utilized for cartographic production. Additionally, Esri’s Production Mapping extension has proven useful in terms of handling layout constraints and customized map elements.

The map output process is done through a series of Python scripts that take advantage of the 64-bit background processing option within ArcGIS. Using this approach, the time taken to output each map was reduced by 10-15 minutes per map. Initially, draft maps were output to 300dpi PNG files for proofing and review. Feedback during this proofing process was used to further refine various aspects of the map series. Two types of georeferenced maps will be produced for distribution: collared and un-collared. The collared version will include all layout elements (i.e. legend, inset maps, title, . . . ) whereas the un-collared ones will be limited to the area within the data frame.

Significant effort was put into establishing an appropriate symbol set for this map series, and DGI staff consulted the USGS Topographic Map Symbols publication for guidance. Some of its symbols were adopted while others were adjusted to enhance readability. Once a symbol was selected, it was added to the KyTopo.style library using the ArcGIS Style Manager. This tool has proven to be an effective and efficient way to manage symbology for the production effort.

Typography, or cartographic labeling, is another aspect of this process that has received a tremendous amount of attention. Feature labels, titles, legends and notes are just some of the text-based components of a cartographic product. Using the correct typeface for each element is critical when compiling a quality map. Discounting the importance of typography during cartographic production can lead to a map that is difficult to interpret or one that draws the user’s attention away from the subject. Per the principles of thematic map design, serif typefaces were used for the map title, layout elements such as graticule labels, and hydrographic features.  Road shields, road names, elevation features, and some selected layout elements employ sans serif typefaces. Feature label placement was handled by enabling Maplex functionality in the map document. Hours were devoted to fine tuning the Maplex labeling rules so more prominent features were placed prior to those of less importance.

Every great map series includes both index and inset maps so users can see the location of each map tile in context. The KyTopo index map is situated in the upper right corner of the layout and highlights the given map tile on a statewide view. The inset map has been positioned below the legend and shows the eight tiles that surround each map. Including both of these components on the map has proven to be quite helpful. Using separate data frames for each, in conjunction with Data Driven Pages functionality, made this an automatable task.

One of the most frustrating layout elements to deal with was the legend. ArcGIS has some nice legend generation tools but DGI was unable to fully utilize its output. The legend created with the automated tools just didn’t produce the most desirable results. For example, the symbol for spot elevations would appear in the legend but the actual elevation value would not be placed beside it. Reluctantly, a partially manual process that uses Adobe Photoshop and Illustrator was put into place. It is a bit cumbersome, but the resulting legend is much nicer and better reflects the features within the map series.

At the time of the writing of this article, draft maps for KyTopo have only been generated for 394 of the 549 tiles. This is being driven by the current availability of LiDAR data for the Commonwealth. Statewide LiDAR coverage should be a reality by the end of 2017. Once that has been completed, contours will be generated for the remaining tiles and final map production will commence. It is planned that the map products and ancillary data elements will be made available on the KyGeoNet by Spring of 2018.

Kentucky’s Enterprise GIS Implementation – A Decennial Update

Background

A little over ten years ago an article entitled “GIS as a Utility: Kentucky’s Enterprise Implementation” appeared in Esri’s 2005 summer edition of ArcNews. The article provided an overview of Kentucky’s new Enterprise GIS implementation, discussed the challenges associated with making spatial data accessible in a networked environment, and highlighted how various agencies were beginning to leverage this new resource. It has been over a decade since that article’s publication, and the Commonwealth’s enterprise GIS has matured and become a critical component of business processes both within and outside State Government. This article outlines the efforts managed by the Kentucky Division of Geographic Information (DGI) that have made this implementation successful and sustainable throughout evolving technologies, tight budget cycles and changing policy directions.

The Keystone

One of the least desirable tasks in information technology is documentation. No one likes to document code, routine processes, or data for that matter. In the GIS world, creating “metadata” is the task that no one likes to see on their “to do” list but successful implementations require that it is completed on a layer-by-layer basis without exception. Like it or not, metadata is the keystone of Kentucky’s spatial data services. It has been tough at times to get agencies on this bandwagon, but once they’ve bought in, the value becomes more apparent. The policy states, “All spatial data resources shall have a complete metadata record in order to be included in the Commonwealth’s spatial data repository.” The existence of and strict adherence to this policy has had a positive impact on geospatial data integrity that carries on today.

Back in 2005, the Kentucky Geography Network (KyGeoNet) was based upon ArcIMS Metadata services, and there were less than 50 metadata records created by a half a dozen publishers. The whole concept of creating metadata was new and many just saw it as something else they had to do on top of everything else on their plate. For many GIS practitioners, it was a low priority until they realized that the Commonwealth’s spatial data repository would not grow if metadata was not created for the valuable resources scattered across the GIS community.

The value in making geospatial data accessible certainly outweighs the amount of effort required to complete a minimal metadata record and publish it to a repository. Essentially, this is a form of “cost avoidance” in that if users can find a resource, read the metadata to learn about its characteristics, and then download it for their use, they are less likely to call or e-mail with questions or requests. This becomes quite apparent once you’ve fielded 20+ calls about a given dataset and then realize that a published metadata record could have answered questions about the resource. Being asked the same question over and over again makes for grumpy GIS staff.

Fast forward to 2016 and there are now approximately 700 metadata records being actively managed by over two-dozen responsible publishers on what is known as the KyGeoPortal. The service is currently based upon a recent release of Esri’s open source product known as Geoportal Server. This solution includes the ability to search for and create metadata records associated with web mapping and image services, as well as downloadable datasets, static map images, standards documents and web mapping applications. It is a wonderful resource that is leveraged frequently by thousands of users on a monthly basis.

Enterprise Approach

As noted in the 2005 article, KyVector and KyRaster are the primary enterprise-based services that are accessible to the hundreds of ArcGIS Desktop and CAD users within Kentucky State Government. Each user is on the Wide Area Network (WAN) and enjoys fast, network-based access to these geospatial services hosted at the Commonwealth Computing Center in Frankfort, Kentucky. This level of service would not be possible without Commonwealth Office of Technology’s (COT) robust WAN and server infrastructure as the delivery mechanism.

Centralizing the data repository has reduced direct agency storage costs and eliminated the issue of outdated data residing on agency-based file servers. Agencies no longer have to expend resources on updating data that originates from external sources. All data is current, easily accessible, and includes associated metadata. This level of data availability and integrity promotes confidence in results when GIS technologies are utilized for inventory, planning, response, or business process decision support.

KyVector

KyVector, an ArcSDE-based server solution that runs in conjunction with Microsoft SQL Server is hosted on three separate physical boxes. One server (kysdewww) is dedicated to providing vector-based data to State Government agencies that host their own web mapping services and applications. Another server (kysdewan) is reserved for the hundreds of ArcGIS Desktop users on the WAN, while the third is used for staging and failover/outage scenarios. This proven configuration reduces contention for server resources and ensures that data delivery to users and applications is carried out in the most efficient and effective manner.

KyVector Layers in ArcMap
KyVector Layers in ArcMap

All data resources housed in KyVector have met the prerequisites of having a full metadata record and having been published to the KyGeoNet. In 2005, it was noted that 125 layers were in KyVector. Today, the number has more than doubled and stands at just over 300 layers. New layers are added periodically as they are created or if there is a need to share the resource across the enterprise.

Access to KyVector has been streamlined by using layerfiles that include connectivity properties, appropriate display scale thresholds, and suggested symbology settings. The organization, maintenance and distribution of the layerfiles is carried out by DGI. Users can start a new, or add to an existing, map document with ease by browsing a thematically organized folder of layerfiles.

Weekly data updates to KyVector, are fed from the agencies to the staging server then subsequently moved to production during the update procedure. Users access this resource with confidence knowing that it is the most current version available at any given time.

KyRaster

A decade ago, KyRaster was ArcSDE-based but newer technologies have prevailed. ArcGIS Image Server is now employed to provide users with access to raster-based data such as aerial photography, topographic maps, digital elevation models, and land cover. The primary benefit of ArcGIS Image Server over raster datasets stored in ArcSDE is the significant reduction in the time needed to process raster data so that it is accessible to end users. In the past, days or even weeks would be consumed just loading imagery into a raster dataset in ArcSDE. But now, with mosaic datasets and Image Server, we are able to get data out to the users in hours, or days at the very most.

KyRaster Layer in ArcMap

Additionally, DGI’s raster storage footprint has been reduced by employing function chains within mosaic datasets. This functionality allows us to store the data once but serve it up in multiple projections, with different band combinations, or with special rendering options. For example, a function can be inserted into the chain of a digital elevation model (DEM) that allows it to be rendered as hillshade, shaded relief, or percent slope. The DEM is only stored once on disk, however the functions can be applied to each request on the fly.

As with KyVector, ArcGIS Desktop users connect to KyRaster using layerfiles that include connection properties, display scale thresholds, compression settings and custom rendering options. The performance of Image Server is on par with ArcSDE on the WAN, and those that aren’t on the State’s network have learned to change compression settings on the client-side to achieve better performance on slower networks. This approach has worked well in state field offices, at local governments, and by private sector users such as engineers, surveyors, and consultants.

Web Mapping Services

Both KyVector and KyRaster are the backbone of the Commonwealth’s publically accessible web mapping and image services. Dynamic and cached map services are hosted on kygisserver.ky.gov and provided in Web Mercator projection using ArcGIS Server. These services power hundreds of web mapping applications internal and external to State Government. The Commonwealth Base Map and the Commonwealth Street Base Map are the two primary cached services, but other statewide imagery and land cover layers have been cached as well.

The Commonwealth Base Map Cached Service

The balance of the services are considered to be dynamic, as they pull data directly from KyVector to fulfill every single server request. Each time a user zooms in, zooms out, pans one direction or another, a request is made to the map server which in turn reaches out to KyVector for the data.

Average Monthly Map Server Requests for 2016 (through July):
9 million requests/several thousand unique visitors

Kentucky’s image and elevation services are hosted on kyraster.ky.gov in Kentucky Single Zone Projection using ArcGIS Server and the Image Server extension. Employees with ArcGIS Desktop in State Government are the primary users of this server, however there are a growing number of users outside the WAN. When ArcSDE was the server solution for imagery, only users on the WAN could gain access. Image Server now allows the Commonwealth to meet the needs of internal and external users with the same computing infrastructure yet still maintain a high level of performance and availability.

KyGovMaps

Like many other users of geospatial technologies, DGI has incorporated ArcGIS Online (AGOL) into its solutions and workflows. AGOL is Esri’s scalable and secure software-as-a-service cloud-based mapping platform. It includes a rich collection of web mapping application templates, visualization and analytical tools, and ready-to-use data sources that make geospatial resources more accessible and user friendly. DGI’s organizational site on AGOL, KyGovMaps, showcases a wide variety of Kentucky-specific web maps, applications, and services. Data and maps that were once only usable by those with expensive GIS software are now available to most everyone. GIS isn’t just for propeller heads anymore!

A customized gallery page on the KyGeoNet makes it easy to locate featured web maps, mapping applications, and thematic galleries that interest a wide array of users. Lately, some of the most popular applications have been those in our collection of Story Maps. Recreational resources, imagery, historic landmarks, demographics, elevation data, and physiographic regions are a sampling of the topics covered using story map templates that we’ve customized.

All of the current web mapping applications hosted by DGI were built using a customizable Javascript-based template. These applications employ a responsive framework and thus can be used within any browser and on any platform. Find a trailhead at a State Park, check the weather, get the soil characteristics for where you are standing, or locate the closest place to put your boat in the water and do it using your desktop, tablet or phone!

The Next Decade

If the pattern continues, combined total server requests for the 2016 calendar year will easily exceed 250 million. This alone is a true testatment to the success of the Commonwealth’s Enterprise GIS implementation. The growth in adoption and usage of geospatial technologies during the past decade has been astounding, and Kentucky’s capabilities in this realm have kept up with the pace of advancement. It will be interesting to look back at this, and the preceding 2005 article, during the middle of the next decade to see where we stand. Live data feeds, UAV acquired imagery, and 3D visualization are just some of the new trends that will shape the makeup of the Kentucky’s Enterprise GIS down the line. Stay tuned!

KyMotoVan – Report #10

Nerf Bars:  I spent weeks looking at running boards and nerf bar options for the NCV3 Sprinter. There were abundant options for “generic” running boards. Many looked like they “kinda” fit and one person told me their’s were sturdy even with 5 kinds getting in and out each day. In the end, I went with the black powder-coated Aluminess Sprinter Nerf Bars for my 170 WB Sprinter (with a roof-mount AC unit) . . . the AC part will be important later on.

First of all, I must say that the nerf bars are extremely well made. My Father is a decent welder and he too agreed and examined the craftsmanship in great detail. They know what they are doing and do it well. Additionally, the staff was easy to work with when ordering. Coordinating a freight shipment from the San Diego area to a local business was painless to coordinate.

Installation of the passenger side was tackled first. Here is where the AC unit comes into play. Oddly enough, the AC lines for the roof-mounted unit emerge from above just behind the front door steps. On both sides. Unfortunately, the brackets for the nerf bars are impacted by the location of the AC lines.

After lots of examination and measuring, some modifications were made to the front two brackets. The modifications allowed us to kinda tuck and turn the nerf bars up behind the AC line with plenty of clearance. Holding them into place also told us that it was topping out on the back bracket so about 3/4″ was taken off the top of each of those.

We then used a floor jack under the rear bracket to position and push it up into place. Two holes were drilled in the vertical portion of the underbody where the brackets rested. The floor jack was moved up to the next bracket and once again we got it in place and drilled the holes and installed the mounting hardware. A similar process was followed for the last three brackets as we worked our way towards the front.

On the last bracket, the stainless steel screws were used to pull it up flush with the bottom of the step. It worked very well and end up being consistent looking from front to back.

From the look of things, doing the driver’s side was going to be more difficult. As with the other side, we took about 3/4” off the top of the back two brackets before starting. Both of the front two angle brackets were removed and the welds were ground down to a smooth surface. All but about 2 inches was cut away from the top of the second bracket from the front.

The heater hoses are not a problem at all although they look imposing. I removed the 10mm nuts on the AC hose bracket and removed the factory threaded tab. Removing the next 10mm nut up the line on the AC hose made it easier to reposition the hose during the install.

With these modifications made, the nerf bar has to be rotated into position so that those front two mounts tuck behind the AC hose. Very similar to how it was on the other side. Luckily it totally misses those heater hoses! A floor jack was used to position the rear mount and a barrel jack on the front three brackets as the holes were drilled.

In this instance, the rear bracket was set to straddle the back two body mounting points. On the passenger side the foremost rear tab was behind the foremost body mounting point. Also, it leaned a bit inward towards the center of the vehicle whereas the other side was more vertical. Typical body variations I’d say as it lined up well on the outside and along the bottom of the van.

Rear Bracket

Unlike the passenger side, the front bracket did need some spacers to do it right. We cut the piece of aluminum that was removed from the second bracket in half, drilled a hole in each half, and used those as the spacers. Worked very well. It looks really good, feels sturdy, and is “symmetrical” with the other side in terms of its positioning. I used most all of the supplied hardware.

Mounted!
Mounted!

Glad to get this all behind me. It is certainly easier to get in and out and as noted by a couple folks, it does provide some “side” protection as well. I really like the way they look and once again the craftsmanship is great.

Special thanks for my Son and my Father. My Son assisted with the passenger side and my Father on the Driver’s side. Both felt we’d done a good job of really securing to the body in spite of the dreaded AC lines from the roof mounted unit.

Getting new tires put on the van next week and still working on partition door mounting options. Stay tuned!

See you on the trail!

The Right Tool for the Job

As with most things, it is so much easier when you have the right tool for the job at hand. We spent nearly one hour at a large downed tree that had two trunks a couple weekends ago. The little saws are nice but we ended up needing the hand saw so we wouldn’t get them wedged. It was slow going for a while but we had Philip along to help so that was good.

Gearing Up!
Gearing Up!

This past weekend we headed out to finish up some course work and Jesse asked if we needed the big saw for anything. “Yes!” was the answer. There were three places on that old logging road I’d been clearing where big logs needed to go. One of these spots was where we spent an hour a couple weeks beforehand. Luckily, the BIG saw fit right into my carrier with little issue. It fit well but it was so much heavier than the little saw. I immediately turned back my steering damper. I didn’t need that type of help with the monster saw hanging over my front fender.

If you want to check out some of the area I’m talking about take a look a these three videos. Winter trail work in Kentucky is always a great time. This is the only time of year you can tackle all the thorny plant matter out there in the woods.

See you on the trail!

A new view . . .

At the most basic level, the header photo on the blog has changed. The photo was taken this Spring in Wolfe County, Kentucky. My attempt to capture the landscape does not do it justice. There were rolling hills and massive cliffs in the foreground and ridge tops from a couple counties away with water tanks perched upon high so as to achieve maximum pressure. I changed the header because a friend noted that there were snow capped mountains on my page. Having not been to Kentucky before, he wondered if we really had snow capped mountains like out West. So, I switched it up for a new look and to let him (and others) see what Kentucky looks like.

Additionally, I just returned from an extended vacation to a small city named “Stanley” in the Sawtooth Mountains of central Idaho. Returning from a trip like this usually leaves me with a different take on things. A new view or perspective on life . . . or maybe not so much “new” but possibly more “energized” . . . maybe that is a better way of stating it. Being off work for a month causes me to contemplate retirement and everything that goes along with it. I’ve been planning for retirement for many, many years now and hopefully Kim and I will be able to live comfortably in our later years.

I’m also drawn farther and farther away from my desire to “compete” in off road racing. Doing an Enduro from time to time seems attractive, but I have little interest in racing hare scrambles. I enjoy working on the courses in the Spring, but anything after June is just plain brutal. The heat, humidity, bugs, and thick undergrowth make trail cutting miserable at best. It takes all the fun out of it . . . makes me think about not doing it at all and just spending that time riding and having fun.

My view of work also changes a bit after being gone for four weeks. I’m certainly re-energized and I know there is plenty to get done in the next several weeks. Having fun and challenging things to do at work keeps me engaged and leaves little time for getting bored. I’m lucky to have a great job that I enjoy and that allows Kim and I to take off such long periods of time. It’s always good to have “a new view” of your life . . .

See you on the trail!

Looking forward . . .

Just like March, April came and went quickly. Today is the first day of May so that means I have 18 days left to finish the course in Wolfe County. After that race on May 20th I’ll have 5 weekends to get the one in Mercer County completed. I’m going to let Jesse and David take care of Horseshoe Bend which is just 3 weekends after the Wolfe County event. I have little to no desire to work at that place especially since I learned that mud buggies are going down in those woods now. I’ve never been a fan, but lots of racers really like that venue . . . just not one of my favorites. You can check out the locations of all the KORHS races on our new interactive map. It has some neat tools and base layers with aerial photos and topographic information. You can use the bookmarks to zoom directly to each of the venues. Check it out!

It’s has been fun working on a new piece of property. Wolfe County has a different variety of plants, soil types, and critters that we get to see here in central Kentucky. The problem is that this time of year I start to get burnt out on the whole course layout thing. I start to dread doing the course work when it is hot outside and it got quite warm this past weekend. This is when I start to look forward to doing some traveling and riding out West. Just plain fun . . . no worries about course layout deadlines or any work-related items at all. Getting away from it all and having no schedules to pin me down for a while is a worthy recharge for Kim and me. This is something we both look forward to all year long!

What are you looking forward to?

See you on the Trail!

The weather . . .

It is true that I have some addiction to weather. I check the Precision Agricultural Weather Forecast from the UK Agricultural Weather Center for my county at least 2-3 times a day and certainly have my Kentucky Weather Mapping site on the KYGEONET up in a browser window if a big front is coming through. Generally, I keep a close tab on the weather.

Knowing what’s going on with the weather helps me plan a great variety of things. Not just what to wear (although that is a bonus) but what it is going to be like on Saturday or Sunday. Is it going to be good enough one day or another to work on trails or ride? Anything above 20 degrees is fine with me for getting out. It’s all about the gear!

Additionally, I consider the weather, or more specifically the seasons, when planning vacations, work outdoors around the house, or even course layout. It plays a big role and so many folks just exist within it and take it for granted. Most aren’t happy when it rains or snows, but it just a part of it all. The more snow the better!!

Remotely, I watch the weather in some places out West. My favorite for sure is the Sawtooth Camera. It shows snapshots of the Sawtooth Mountain Range in Central Idaho from a person’s home in Stanley, Idaho. A place that we really like to visit both winter and summer. I’ve been there when there was 3 foot of snow on the ground and when it was 80 degrees (which is hot for this mountain town). Both are really neat and are a great contrast to the climate here in Kentucky. Another place we like to monitor remotely is the Tetons! The National Parks Service has an air quality page and web camera that shows the Tetons from a viewpoint east of the mountains.

One other thing I like to track is the snowfall amounts on two summits in Central Idaho. One is the Galena Summit that you go over each time you head up to Stanley through the Sawtooth Valley. The other is the Atlanta Summit that is west and south a bit of Galena. The Snowtel sites show the snow depth and other cool info.

So, have fun with the weather! I find it to be very useful and engaging!

See you on the Trail!

 

The view from above . . .

One nice part about my job doing GIS for State Government is the access to the most current aerial photography and other data layers. The Federal Government through the National Aerial Inventory Program (NAIP) has acquired leaf-on aerial photography of the entire state at a 1 meter resolution every two years since 2004. In 2006 2 foot resolution (much better) was obtained. We just got the 2010 photography a couple weeks ago and have been working to mosaic it all together and make it available for everyone to use and/or view.

Horseshoe Bend - Summer 2010
Horseshoe Bend - Summer 2010

Checkout the photo above of Horseshoe Bend taken this summer as a part of the NAIP effort. You can see every twist and turn of the MX track and if you know where to look you’ll see where the KORHS course crossed some fields and where it tied into the MX track. If you look closely you can see where scoring was just inside the little kids track. Also, every jump and corner is very clear on the Supercross track on the left hand side of the image.

I cruised around the state looking at the new imagery and in most of the KORHS race locations there were few indications of our presence that were visible in the imagery. Mainly, the scoring areas and some corners on the grass track sections. These types of things are visible at the Sawmill in the area next to the road. Now in the case of Salt River Run, the imagery was acquired before the event. Thus, there is no sign there was a race there this year, but you can count the roll bales in one of his fields with great precision!

Below is a link that will allow you to view the new 2010 imagery. We haven’t exposed it in any of our public facing sites yet, but these public “services” are accessible and allow you to view it in a simple Javascript viewer in the interim.

2010 Imagery Service Javascript Viewer – Use the little buttons to zoom in and out or Shift+Click and drag to define an extent to zoom to.

Let me know if you have any questions about the aerials and when we get it out in an easy to use viewer I’ll let everyone know.

See you on the trail!

Change is in the air . . .

It will dip below 50 degrees tonight . . . that is a welcome change. At work, the Governor has begun letting go non-merit employees . . . that’s been an interesting change for many. Additionally, Kim and I may have an opportunity for a change, a good or even great one . . . only time will tell on that one.

What I’m really excited about is the cool weather and the potential to get out and do more riding and work on single track at our riding place. Not really sure if I’ll race the last two races. If it is wet, I will race Horseshoe Bend, but Hardwick creek is getting really old just running the same beat up course over and over. Just don’t feel the need to compete . . . I like to go fast when it is comfortable but the desire to hang it out there a little on the edge to keep up with my class is just not there. Riding in the A class means you’re always a little on the edge if you’re in the running. Pete and Harvey make it look easy, but they are in a different league altogether.

Slammed some new tire balls in a trials tire and now have two 18′ wheels with THE setup. It looks really funny from the side. You can see the bulge of each ball along the sidewall. I put about 11 pounds in each one this time, a little more than I normally would for the IRC VE-33 knobby. The trials tire only has about 75 or 80 miles on it from Idaho so it should be good to go for the next few weeks. With
