Elevation profile of connected interior spaces

It’s downtown Lexington, summer, and hot. Poor air quality and oppressive heat are hazards for older walkers and those with cranky babies. An interior (mostly air conditioned) pedway exists that connects various buildings downtown and is a walking convenience for many folks. When Lexington has more shady pedestrian paths away from city streets, walking inside wouldn’t be so inviting and necessary.

2016 Cumberland Gap trail map, hiking information

2016 Cumberland Gap trail map and hiking information

The update to our Cumberland Gap National Historical Park is almost complete. Much like the old map, our 2016 version is a 1 inch to 1/2 mile scale map with 50-foot contours, trail elevation profiles, and  GPS-mapped trails shown in vivid full-color printing. This year we added a layer that shows density of canopy coverage and GPS-mapped Caldwell Gap Trail. The size of the park has increased since our last update, so we’ve included most of the additional land.

East End Preservation Project map

East End Preservation Project map

A map historically significant homes and structures in the Martin Luther King and William Wells Brown neighborhood associations; many have connections to African-American work and life over the past two centuries. It was a pleasant afternoon walking Onabits, aka lil’ blue eyes, and taking photographs in my neighborhood. With the growth of the north Limestone corridor and the planned development of the Midland and 3rd street area, it’s important to recognize the history that resonates through downtown Lexington. We’ll come back in 10 years and see how many of these structures remain.

Base map for Salt Lake City hiking

East of Salt Lake City

East of Salt Lake City

A client needed a base map for an upcoming hiking guide to areas east of Salt Lake City. We came up with a simple, clean photoshop file using NAIP aerial imagery and 1/3 arc-second seamless DEM. The NAIP was used to create an NDVI and estimated canopy cover and the DEM was used as a shaded relief and to generate 40 ft contours. The NDVI and shaded relief were used for emphasis and helped make the aerial ‘pop’ a little more. Lakes and perennial streams were added, but as you can see the don’t register perfectly with the aerial image.

Over the past year, we’ve refined a trail map for the City of Norris, Tennessee. The Norris Watershed Trail Map is probably printed by now and offers GPS mapped trails and mountain biking opportunities. The WPA era dam is pretty cool, too.

City of Rocks and 3D mapping offer teaching moment

With the quality of elevation data increasing, especially with the availability of LiDAR data, we have an opportunity to make unique visuals. Recently Wolverine Publishing needed maps developed for the climbing area, City of Rocks in Idaho. The project needed high-resolution maps and the data was available through public sources. We like making the physiographic base maps for recreation areas and this offered a special challenge.

Lexington Bike/Ped versus Car Collision Analysis

Website of collision maps

Website of collision maps

For a GIS course at the University of Kentucky Department of Geography (GEO 409), we mapped and analyzed the incidences of car collisions with pedestrians and bicyclists. Using data from Kentucky Crash Analysis Wizard (crashinformationky.org), we harvested collisions for Fayette County from January 2004 until April 8, 2016, the entire dataset at that point in time. 

The website of collision maps is available here: http://boydx.github.io/collisions/ and the bike map is http://boydx.github.io/collisions/bikes

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.

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…]
