I am a lifelong learner and naturally catalog information I find useful. I created this Maptastic Resources document as a way to systemize knowledge I've found useful and have since shared it with the geospatial community in case others may also find it valuable.
This document features a compilation of GIS portfolio examples, data portals, geospatial communities to join, GIS podcasts, annual map contests, and opensource GIS textbooks. I'm continually adding and improving this as I find additional beneficial geospatial resources. Additions and suggestions are welcome! Feel free to add a comment directly to the document!
