You and your 
grantees have 
amazing insights 
already. Start 
thinking spatially
4 Ways to get 
started:
1. Take the “Maps and 
the Geospatial 
Revolution” class at: 
www.coursera.org/course/ 
maps
2. Collect location data 
on every single thing 
your organization does.
3. Help your grantees 
get discounted licenses 
for ArcGIS Desktop 
through TechSoup.org
4. Tell your grantees 
about spatial analysis.
