Map Portfolio
A collection of interactive web maps built with modern GIS and web mapping technologies. Most of these were created as part of the 30 Day Map Challenge -- a daily mapping initiative where each day has a different theme.
30DayMapChallenge 2026
A new map every day in November 2026. Each one starts with a question and some analysis, built with cloud-optimized point clouds, rasters and vector tiles served directly from object storage.
Eastern Meadowlark Nesting Sites
Interactive field tool mapping EAME nesting sites, CDL hay/pasture and corn fields across the CT River valley from Vernon VT to Claremont NH.
Where your cash works, coast to coast
Type your cash. 38,839 hexagons recolor by the share of people living in a ZIP where a rental cash flows today. Past about $120,000 the map stops changing.
What to clear
The trees that shade the Day 01 field, clustered into clearing zones a surveyor can stake, cut down to the strips whose shadow lands on the field, with the creek trees kept.
Who sees the panels
A viewshed from all 350 homes within a mile of the Phoebus demo layout across the lidar surface, trees and all: 34 see any panel, against 297 on bare ground.
Every house in 1920
The 1920 USDA soil map of Marengo County over the Phoebus ground, then today under it: 550 houses on the old sheet and 77 with a building there now, most of the 1920 roads still roads, and a spyglass that shows the old sheet anywhere on today.
A state in a second
Every acre of Alabama, 1.3 million H3 cells, goes through a siting screen in the browser, and one click swaps the rules for solar, wind, a data center campus or land to option. DuckDB reruns the whole state on every change and finds the largest block that passes; the same screen runs on one county or on all 48 states.
Where rural ends for a 640 ft turbine
One number screens out land before any other constraint runs: above 19 structures per km2, a 1,276 ft home setback leaves under 1 percent of a 1 km cell, measured over every GHSL cell in five Sand Mountain counties. All 245 built turbines in six Southeast USWTDB projects stand in cells below that line, and moving the ordinance from 2x to 3x tip height takes 40 percent of the turbine land that remains.
The turbines at 2 am
Crowned Ridge Wind, South Dakota, from its public PUC filings: 87 turbines and 137 homes run through ISO 9613-2. At full sound power 6 non-participating homes go over 45 dBA; the PUC had 16 turbines shut above 6 m/s, and a greedy planner clears every home with 7. Click a home and the frequency and distance plots move to it.
The line at the gate
The Phoebus demo layout asks for about 528 MWac on a 230 kV line 13 miles away. The map and chart show who is already queued within 60 miles, how few Southeast requests ever reach operation and how long they take, and how much of one circuit Phoebus would fill.
Cut a tree, lose a neighbor
Cut the trees around the Phoebus demo layout or plant a hedgerow, and the browser reruns the line of sight from 350 homes and the December shade on the 2 m lidar surface, only for the rays the edit touches.
