February Meeting 2/19

Greenwood Mapping

Richard Greenwood of Greenwood Mapping will share insights from his 30-year career, starting as a land surveyor and evolving into a GIS professional specializing in open-source solutions. He has developed and supported more than a dozen County-focused MapServers in Idaho and Wyoming. These online maps are powered by his custom web mapping platform, built on MapServer, OpenLayers, and PostGIS. The maps provide public access to geographic data and legal documents, and are essential tools supporting county tax assessors, treasurers, and clerks in their daily work.

Past Meetings


January Meeting 1/15

Turf.js

Tim Welch will present Turf.js, a Javascript library for spatial analysis. He'll cover the basics of what Turf is, where it fits in the toolbox, and how you can piece together its many modules to do useful things using the common language of GeoJSON. https://turfjs.org

December Meeting 12/11

It's our last meeting for 2024. We'll be at Hot Lips Pizza again and on Zoom for those traveling. A little bit of planning and a little bit of scheduling. See you there!
