Tyler Dahlberg of Azavea takes us through the origin of spatial analysis, how it works, real-world examples of how it has transformed decision making processes and data display, and how you can get started. Spatial analysis can help you or your organization simplify complex patterns, improve decision-making and tell your story more effectively.

$15 million in value

40. 5 years:
4,819 bike+auto crashes

79. 5. Check out the
mapping tools at:
selection.datavisualization.ch

81. 6. Join a Meetup group
in your city, like
