What is the Listserv? 

Join the GIS Colorado Email List for peer conversation and a support network. It’s free!

The GIS Colorado Community Email list provides an avenue to ask questions, share resources, and engage with the GIS community within Colorado and beyond. The List uses Google Groups so conversations, suggestions, and solutions can be archived and searchable.
