I'm trying to create a number of widgets that will visualise different data by geographic area, e.g., the Potential Losses for Instrument X in Year Y for the Counties of State Z.
Going down the ArcGIS route I am assuming I need to create a dynamic layer here with all of the polygons for each county of each state defined and then somehow colour them according to data pulled out of a DB showing loss for that instrument, for that county for that year.
Could someone please
- A) validate that that is the correct way to go and
- B) point me in the right direction to some resources to help me learn how to achieve this.
