What are SimMaps?

Originally, SimMaps were intended to be the results of LEAM simulations overlayed on Google Maps that allow the user to view scenario outputs in an accessible manner.  Because of the effectiveness of combining custom maps with Google Maps, SimMaps were soon expanded to support all type of maps.  Examples include landuse change, change by school district, watershed, etc.  For tips on using SimView, click here.

Are the data available for download?

Yes.  All reports, regional plans, base shapefiles, and LEAM results can be downloaded via the tabs at the top.  Reports are available in pdf format.  Shapefiles and LEAM results require GIS software for viewing.
