GIS Colorado is a non-profit organization represented by members of the GIS community throughout Colorado. We started as a group of GIS professionals wishing to help each other to better use GIS technology. With the rapid growth of GIS nationwide, Colorado's GIS community has exploded. Therefore, GIS Colorado has grown to do much more. Besides maintaining a resource directory of GIS users throughout the state, we also host a very popular listserv where GIS professionals can ask thousands of users for assistance or advice. And, GIS Colorado acts as a unified industry advocate for GIS at the state and federal levels.
