Students map Town Branch Trail

Town Branch Trail in maps

Students create many maps and a website for the soon-to-be-built Town Branch Trail during the Spring 2017 semester in the GEO 409 (Advanced Topics in GIS) in the Department of Geography, University of Kentucky. We used mainly open source GIS software QGIS and GitHub to create and publish our maps.

We used mainly open source GIS software QGIS and GitHub to create and publish our maps. For the final project, students grouped into separate teams for web page production, field GPS and photography, story production, and 3D mapping.

An interactive map of the content produced for the final project can be found in the following map:

Sheltowee Trace interactive mobile map

Locate yourself on the ST

We’ve updated our map of the Sheltowee Trace on our ST site: sheltoweetrace.com/hike. The map has symbols for official recreation sites and trails for the Daniel Boone National Forest, Big South Fork National River and Recreation Area, and Cumberland Falls and Natural Bridge State Resort Parks. Of course, it has the ST and mile markers from the northern terminus.

Since we deployed this map last year, we have updated the Leaflet and MapBox JS to make the work with a GPS-enabled device as long as you have a cellular data connection. The points of interests and trails are clickable with useful travel information.

Our next goal is to fill out the map with more scenic destinations and include more photographs. Let us know if you have any suggestions.

Lexington’s Urban Canopy

An exploration of canopy cover measures

An exploration of canopy cover measures

How much tree canopy covers the urban service area of Lexington, Kentucky? Inspired by the Davey Resource Group’s October 2013 study of canopy cover using 2012 NAIP imagery within Lexington’s Urban Service Area, a GIS class at the University of Kentucky created a similar, though limited, evaluation.

Pine Mountain Canopy Tour

Canopy zipline tour mapping assignment

Canopy zipline tour mapping assignment

What wild weekend and mapping task! Boyd led an undergraduate GIS class at the University of Kentucky and endeavored to map and analyze environmental tourism assets on Pine Mountain. During discussions with Pine Mountain State Resort Park, we discovered a canopy zipline tour, one of the first in the state, was being installed in the park. [Read more…]

Town Branch Trail and Density of Healthy Canopy

Which property has the healthiest canopy?

Which property has the healthiest canopy?

Town Branch Trail is a developing shared-use trail connecting downtown Lexington with the city’s outer countryside. The exercise shows the completed and funded phases for the trail, and assesses the extent and health of trees along the trail.

Using National Agriculture Imagery Program (NAIP 2012 imagery an NDVI (Normalized Difference Vegetation Index) was created and then shown as a ratio per parcel area. After viewing the initial results, a student said, “This is a realtor’s map!” and then quickly visited the PVA website to compare property values to its ‘green index.’

Mapping Kentucky’s Wildland Fires with Satellite Imagery

KentuckyWildfires_2012-2014Kentucky has damaging wildland fires, while also using prescribed burns to manage habitat. An unfortunate statistic tells us that most wildland fires in Kentucky are from arson.

This student lab uses MODIS Active Fire Detection products and Landsat 8 near-infrared bands to locate and analyze the largest fires between April 2012 and October 2014. I hope to get point locations of smaller fires from Kentucky Division of Forestry to compare with satellite-based observations.

Arboretum Woods Poster

Arboretum Woods Poster

What can students do with a smartphone, ArcMap, and a linux server? More than just have fun outside!

15 student teams from two GIS courses at the University of Kentucky mapped, measured, and photographed 603 trees in the Arboretum Woods. Each team (which adopted colorful team names) was given (approximately) an acre zone. They used common mobile devices and low-cost apps to GPS and photograph the most significant trees. 

Each team made a poster and presented them during a 2014 International GIS Day event in the Thomas Poe Cooper building on UK’s campus. It was widely attended and praised for the strength of student teams’ achievement. 

UK_Arboretum_WebMap_LinkSince students photographed each tree, we made an interactive map that shows these photos and can be used for geolocation while in the woods. Using Leaflet, GeoJSON, and a Linux server, student SWEB accounts host data that feeds this interactive map: Look at trees now!

Sheltowee Trace online map

screenshot_smallWe’ve started an online map for the Sheltowee Trace, because it keeps getting longer with each new season. This month, it is 319 miles (and some change) long.

This map is mobile compatible and will locate you on the trail if your device has GPS. Try it out and tell us what you think.

The map includes the new extension from Leatherwood Ford to Honey Creek.

On September 20, 2014 a downtown Lexington neighborhood hosted a block party and potluck. Raffles were held, which indeed included some outrageGIS mapping hiking maps. This map is entirely custom and shows only sidewalks and the location of the block party. The map layers two different tile sets. The minimal aspect focuses one’s attention to pedestrian modes of travel, since block parties kick out the cars.

University of Kentucky Alumni Map

UoKy Alumni Districts

Click to view

A slippy map that shows alumni districts for the University of Kentucky. A shapefile of the districts was simplified with polygon edges snapped to align and then converted to a GeoJSON file. Tried to convert to TopoJSON with the hope to minimize file size, but unfortunately with little luck. District centroids were exported and converted to marker icons. A simple example of open source mapping.

We’re almost finished with a 38″ x 13″ map of cabins and ziplines in Cliffview Resort. This is an unusual map, since it is a bird’s eye view with latitude and longitude as the index grid for locating cabins and other destinations. The base map is an ArcGIS terrain dataset with National Agriculture Imagery Program (NAIP) aerial photography draped over a rendered TIN surface in ArcScene. The maps was then composited and illustrated in Photoshop and Illustrator.

Boone Trace, A Kentucky Frontier Trail

Interactive map

Draft of interactive map, try it out.

In 1775, Daniel Boone and his party blazed a route into Kentucky and created the pioneer settlement, Boonesborough. The Trace is often confused with the Wilderness Road, since they follow the same route through southern Kentucky, but the Trace predates the Wilderness Road. Boone established the main road through the Kentucky mountains and into the outer Bluegrass. That road would later be known as the Wilderness Road. Boone Trace leaves the Wilderness Road south of Richmond, Kentucky and travels north to Fort Boonesboro.

Today, plenty of historical monuments exists along drivable portions of the Trace. BooneTrace1775.org describes, “There is a monument at the Daniel Boone Park in Flat Lick, Ky. Emblazoned on it are these words which pretty much say it all–   ‘No other trail is of greater historical significant to the founding of Kentucky and opening of the west (than Boone Trace).'”

This map attempts to show a driving tour of the Trace and aggregates many of the cultural and historical destinations once could visit today. It was designed for mobile web browsers and uses Leaflet to power the interactivity.

Flash-type interactive map, 2004

It’s pretty amazing to see how much dynamic web mapping has changed over the past decade. Before, we had Flash content and static layouts, as illustrated by the Elkhorn City Living Cemetery project. Today, we have data-rich maps that take a fraction of the time to create.

Working on a Cumberland Falls map

July draft of Cumberland Falls trail map

July draft of Cumberland Falls trail map

This July we have started a topographic trail map for the Cumberland Falls State Resort Park. The map will use aerial photography, 20-foot elevation contours, and GPS mapped trails. This two-sided 13.5″ x 19″ full-color map will show the entire park and connecting trails into the Daniel Boone NF, including Dog Slaughter Falls. This map is at 1:15,000 scale. The second map will zoom into the central area of the park and show trails at 1:5,000 scale. We anticipate this will be an awesome map, especially when used under a moonbow.

2013 Veterans Park Mountain Biking Trail Map

4.8-mile loop trail & out and back all on singletrack.

In tribute to Bike Lexington month, we’ve made a new map for beginning mountain bikers. If you’re new to trail riding and want tight, banking turns on fast, easy trail, then visit’s Lexington’s Veteran’s Park.

We created this map as a demonstration of small-area map making. We first walked the trail with a Trimble GPS unit this past winter to accurately locate the trail. We then used Kentucky’s new aerial photography and LiDAR elevation data to make 5-foot contours and heads-up digitized canopy coverage. We also pulled in the impervious and waterbody layers from the new Open Data Portal from LFUCG. This is all GIS data that has been created and/or made available in the past six months.

More nerd alert. The recent availability of small-scale mapping data is awesome. We thought we’d try to see how good this data is and make trail elevation profiles, which is included with this map. While the elevation profile is not perfect at this scale (with perhaps a +/- 8 ft height error for any given point on the profile), it gives a good distance measurement and represents well the relative slope of the trail. Since the vertical scale is not the same as the horizontal scale, the profile exaggerates the pumps & humps a rider faces…which means, the slopes are exaggerated.

Enjoy and tell us what you think.
