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

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!

A Neighborhood’s ‘Green’ Index

NeighborhoodGreenIndex_MLKNAA map showing ratio of property parcels covered in healthy canopy in the Martin Luther King Neighborhood Association in Lexington, Kentucky.

Using National Agriculture Imagery Program (NAIP) 2012 aerial imagery, a Normalized Difference Vegetation Index (NDVI) was created. Values greater or equal to 0.3 were assumed healthy canopy and (mostly) verified by visual inspection from imagery and summer field observations.

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

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.

Woodland Art Fair time, 2014!

Come down to the Woodland Art Fair this Saturday and Sunday, August 16 and 17,and check out our new Sheltowee Trace North map. We have a couple neat projects in the works and would like to hear your trail adventure stories.

Sheltowee Trace North map

Trails in the northern half of the Daniel Boone

Trails in the northern half of the Daniel Boone

We are now printing the Sheltowee Trace North map, which covers the ST and official trails between the Northern Terminus and Mckee in Jackson County, Kentucky. That’s 138 miles of ST and  130 miles of official trail. The map is same scale as our previous ST south maps, but the sheet size has been enlarged to 19″ x 27″ and packs down to 4.5″ x 6.5″. We will also offer a lamination and heat press service to make these maps bomber in the field.

A couple unique additions to this title might be useful for the serious trail enthusiast. The map is formatted to show the trail network of Cave Run Lake and Red River Gorge on single, separate sheets. The new ST reroute around Morehead and new trails in Cave Run are located. Groceries, public libraries, power lines, and pipelines are located. We’ve added 1,000 m UTM grid. What else? Lots of love and devotion for the trails of the Daniel Boone.

Overview

Low resolutions drafts of the press sheets (note these previews require Flash). These have been altered in final version. The only way to see the finished map is to hold it in your hand!

Northern Terminus
Cave Run Lake
Red River Gorge
Southern Gorge, Turkey Foot, and McKee

Just like the South ST map, when the ST leaves a sheet it has a letter in a red box as label to match the trail on the next sheet. Just follow A…B…C… for 138 miles.

Thanks for the input in correcting thre above drafts!

A Postcard from Puerto Rico

Photos and a block diagram of NE Puerto Rico

We recently visited Puerto Rico and explored the island’s public parks and forests. Spanish forts in San Juan are wonderfully preserved by the National Park Service and the El Yunque cloud forest is the only tropical rain forest maintained by the National Forest Service. These ares are public treasures and hard to capture by photography alone. You might have seen postcards with extruded maps of mountainous areas and tourist destinations. That’s the quick experiment here, but done just two-dimensionally.

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.

Some downtown Lexington destinations

Imagine a lot of new people arriving to a downtown hotel and you need to recommend unique destinations for dining. I guess you could give a list that they could yelp, but wouldn’t a paper map add a nice, personal touch?

A small map of interesting places to eat and play

A small map of interesting places to eat and play

We have marveled at the growth of mobile maps that tap in largest collective database ever generated and, unfortunately, the subsequent loss of interest in paper maps. While mobile can help locate you in an unfamiliar city with GPS, the map data can be uninspiring and wildly inaccurate. The problem I suggest is the zoom, since we expect ever complex revelations with increasing zoom levels. We all know it’s a big bummer when you zoom into a blank screen, right? We think a static maps can better stimulate imagination and invite navigation into unfamiliar areas.

This is a small experiment integrating 3D maps, photography, and a few SketchUp models to give a quick sense of place and provide a simple navigation tool to explore the city.
