About the GIS
Many Williamson County departments produce maps and geo-spatial data. The County's Geographic Information Systems (GIS) staff help departments by providing the infrastructure and tools to create the maps and data they need. Many of the data sets and maps on this site have the GIS staff as a contact, but the data is maintained by another department. In some cases, data may be created by other government agencies and compiled by the County.
