National Land Cover Database on SheltoweeTrace.com

Two new layers have been added to the web map for the Daniel Boone NF and Big South Fork NRRA: the National Land Cover Database (NLCD) for 2021 (mrlc.gov) and mined lands, 1985–2020 (skytruth.org). The NLCD is a 30-meter resolution (each cell is 30×30 meters) land cover dataset showing each cell’s dominant land use.

The cells are symbolized to show features significant for the area, such as multiple types of vegetation cover, the density of the built environment, and barren land. Inside the NF and NPS boundaries, barren land is likely to be exposures of bedrock, boulders, and earthen materials. For example, it shows Cumberland Falls. Outside of these boundaries, barren land is likely mines or construction sites.

While the layer is low-resolution compared to the aerial photography layer, the NLCD helps us quickly understand landscape conditions that would be tedious to interpret from aerial photography alone.

One can identify the distribution of basic forest types and habitat patterns. The NLCD can be useful for understanding the extent of the wildland-urban interface — a vital consideration for Trail Towns, maintaining wildlife corridors, and managing tourism development in the region.

The NLCD layer, in conjunction with other layers on the web map, provides a comprehensive view of the public lands in the region. Before your next trip to the Daniel Boone NF or Big South Fork NRRA, take a look at all layers to get a sense of the landscape you will be visiting.

Yahoo Falls

Yahoo Falls Picnic Area is located in the Big South Fork National River and Recreation Area in Kentucky. The scenic area contains short hikes and overlooks of the Cumberland River and Yahoo Falls, an impressively tall waterfall. The area is surrounded by the Daniel Boone National Forest with a variety of trails and camping options. You can create a 9-mile loop hike by combining the Yahoo Falls Trail, Sheltowee Trace, and USFS 602 & 612 trails.

Backpacking tips. While no camping is allowed in the Picnic Area, Alum Ford primitive campground is about 2 miles south on the Sheltowee Trace. Big South Fork manages the campground and it is $15/night. There is no water or electricity at the campground and cellular service is weak along the Cumberland River. Hit me up for additional tips. Get lost and have a blast.

Ridge Trail to Hensley Settlement

With 2,000 vertical feet, the hike to Hensley Settlement is a challenging mountain adventure. Cumberland Gap National Historical Park is Kentucky’s only mountain national park and sees the fraction of visitors that other parks and forests see. Why? It’s not easy to get to the Hensley Flats, a mountain-top grassland that the Hensley-Gibson families cultivated and lived for decades. The shortest route to Hensley is via Chadwell Gap, a 4-mile one-way trip. It’s steep. The next option is via the Civic Park trailhead, an 8-mile one-way trip. It’s steep and long. But, you’ll visit incredible destinations and overlooks, including the White Rocks overlook and Sand Cave, one of the largest rock shelters in the region. For an epic day or overnight, start at the Wilderness Road campground and take the Gibson Gap Trail to the Ridge Trail. You’ll be alone in the wilderness. When you get to Hensley, prepare yourself for a proper, crystal-clear mountain high.

Backpacking tips. This national park requires a free permit to camp in the backcountry. The cabin at Martins Fork, with three bunk beds and a fireplace, can be rented. Black bears are very active in the park. Drinking water can be hard to find on the Ridge Trail. Hensley Settlement has a water spigot that is available from spring through fall. The larger streams flow all year. The maps in the video show campsites. Hit me up for additional tips. Get lost and have a blast.

outrageGIS.com turns 25

outrageGIS.com started in 1999 and has been continuously online since then. The first version of the website had this animated GIF. Check out the evolution of the site on the Wayback Machine.

outrageGIS mapping in 1999

While we are known for trail maps, we started mapping for video animation and broadcast graphics. You might remember your nightly local news in Kentucky and seeing maps—we might have contributed to that graphic.

In the early 2000s, we slung on a Trimble Pro XRS backpack GPS unit, outfitted a one-color offset press studio, and began printing spot and process color maps. Our first title was the Red River Gorge trail, a two-color map that we sold in local gas stations. We then printed titles for the Big South Fork, Great Smokies, Cumberland Gap, and the Daniel Boone National Forest. We did numerous contract maps for state parks and non-profits, and even an audio driving tour, The First Frontier Audio Driving Tour.

In 2008, Boyd started teaching at the UKy Department of Geography and accepted a faculty position in 2018. His work focuses on terrain modeling and topographic mapping using lidar data. Periodically, outrageGIS mapping is brought into the classroom to demonstrate web and digital media technologies.

How far do you have to travel to find adventure?

If you live near downtown Lexington, you don’t have far to travel to find sidewalks and shared-use paths that provide an escape to a nascent wildland.

Town Branch Trail is an example. Lexington was built on this stream called the “Town Branch of the Elkhorn.” It was the industrial heart of early Lexington. Most cities have industrialized spaces that become abandoned. These derelict landscapes are primed for recreational and educational opportunities.

Wherever you live, advocate for building local trails.

Rowan County Explorer

Over the years teaching GIS & mapping, Boyd has tried to connect his students with real-world mapping opportunities. One such opportunity emerged when Rowan County, Kentucky, wanted an interactive map showing trails and tourism destinations in the area. Workshopping with students in GEO 305 (Elements of Cartography) and later MAP 672 (Programming for Web Mapping) in UKy’s Department of Geography, he drafted a web map.

The criteria for this map were that it needed to be completely open source (without relying on any for-fee platforms) and self-contained—the project lives in a folder that could be dropped into any web server and would just work. This project uses LeafletJS and public base maps from Kentucky DGI.

The page departs from the traditional web map; marginalia, typically on a print map, was added to this map. A viewer can zoom into the legend! While the creative choices made on this project offered a fulfilling experience, students have their own trajectories and soon pivot interests after a course is finished.

The project is a draft, but it is active. Tell us what you think: https://outrageGIS.com/rowan

New base maps for Sheltowee Trace

Find high-resolution aerial imagery and shaded relief maps for Kentucky (and some for Tennessee) on SheltoweeTrace.com.

Base maps for sheltoweetrace.com
Base maps for sheltoweetrace.com

We’re adding new base maps for our Sheltowee Trace map. The current maps are:

  • Default map shows a generalized shaded relief, hydrologic features, and public land.
  • Aerial photography shows 2-ft pixel resolution, leaf-off 2019 imagery.
  • Shaded relief (KY) uses KyFromAbove point clouds from 2010s to create a shaded relief detailed enough to show trail and road beds.
  • Topographic (KY) shows the Topographic map series created by the Kentucky Division of Geographic Information.
  • Topographic (Maptiler) displays a modifed Maptiler Outdoors base map. It is a global base map pulled a variety of open-source data. Trail and other information portrayed on this base map is not maintained by outrageGIS mapping. Also, elevation contours can show errors around 100 feet.

Cumulative elevation gain calculator

How much elevation gain did you have on your last Sheltowee Trace hike? We built a calculator and elevation profile on SheltoweeTrace.com.

Cumulative elevation gain calculator on sheltoweetrace.com
Cumulative elevation gain calculator on sheltoweetrace.com

The data used in the calculator is pulled from lidar point cloud elevations created in the mid-2010s. Digital elevation models (DEM) derived from these point clouds have a 5-ft spatial resolution and are detailed enough to show wider trails in shaded relief rendering of the DEM. The point elevations for the Sheltowee Trace are sampled every 1/10th of a mile and allow for calculating gains between mile markers with a single decimal place. The result shows both southbound and northbound gains.

Down arrow?

When you encounter a trail navigation sign, you understand left, right, and forward. But, does down mean back? This eight-year-old said yes and quizzed me on it at Berea Fort Mountain.

Trail maps for the Salato Hiking Trail

How many times have you taken a photo with your phone of a trailhead kiosk map? Inside the mailbox were neatly folded paper maps made by the Kentucky Department of Fish and Wildlife.

Terrain Explorer

In this web map, we explore how to use different elevation models in 3D maps. The KyFromAbove project collects and maintains high-resolution elevation data and aerial imagery for Kentucky. The bare-earth Digital Elevation Model (DEM) was created from a lidar point cloud. This is the typical elevation model that we use. The same point cloud was then filtered to create a Digital Surface Model (DSM) showing above-ground elevations, like buildings and trees. Both of these elevation models were converted to terrain tiles to use in web mapping applications. MapLibre GL JS 3D features terrain rendering with RGB-encoded elevation raster tiles.

Terrain Explorer
Explore different terrain models at outragegis.com/terrain-explorer/

The sliders allow the viewer to change the vertical exaggeration of the DEM and DSM. If geolocation is enabled, a track will record the viewer’s location. That track can be downloaded as a GeoJSON (works in Chrome).

This was a project in the UKy Geography MAP 675, a course in the department’s Digital Mapping MS graduate program. The aerial imagery and elevation data are from 2019.
