GIS

Welcome!

The City of San Marcos provides geographic data in the form of interactive maps, PDFs, and downloadable shapefiles. Interactive maps allow public access to Geographic Information System (GIS) data in a user-friendly environment, which can be used with little or no training. Additionally, users can download static (paper) maps in PDF format and GIS data layers in shapefile format.
