Small Batch Maps

Your data has a geography. I make it visible.

From raw spatial data to interactive maps — pipelines, analysis, and cartography.

Selected Work

Geospatial tools I'm building with open source and AI-assisted workflows.

Geomockery

Generate synthetic GeoJSON and Shapefile data in the browser. Draw a boundary, configure geometry types and rule-driven attributes, export. No server, no signup.

Next.js · OpenLayers · Turf.js

Demo GitHub

Santa Fe Detour

Calculates optimal paths then uses network-aware analysis to score nearby detour stops — historic sites, food, scenic overlooks — by exact time and distance cost.

React · FastAPI · MapLibre GL JS · OpenRouteService

Demo GitHub

Ghost Forest Watcher

NDVI change analysis for the East Troublesome Fire area, Colorado. Classifies Sentinel-2 imagery into vegetation health bins and surfaces results through a Streamlit interface, REST API, and H3 hexagonal aggregation.

Earthtile Finder

STAC API browser for satellite imagery. Search Sentinel-2 scenes by map extent, date, and cloud cover — preview footprints, scan thumbnails, download COGs.

About

I'm a geographer and cartographer from Durango, Colorado. I'm now based in Santa Fe, New Mexico, where I spend my off-hours practicing yoga and trail running in the Sangre de Cristo Range.

I finished my PhD in Geography at UW–Madison in 2014, where my research focused on web mapping with emerging open web standards and open source tooling. From there I designed, built, and taught the graduate-level digital mapping curriculum for New Maps Plus — an award-winning program whose students have taken home four NACIS student dynamic map competition wins.

I stepped away from academia in 2024 to explore what these tools could do in industry, government, and the nonprofit sector. That curiosity is still what drives the work.

Conservation teams, nonprofits, and research groups hire me when they have a spatial data problem and no in-house GIS developer.

Let's work together

I'm open to project work, collaborations, or just a good conversation about maps.
