The acronym STAR*Map is the trademarked name for the Southeast Texas Addressing and Referencing Map. Created and maintained by the Houston-Galveston Area Council (H-GAC) and the Geographic Data Committee (GDC), STAR*Map is a digital base map and database that covers a multi-county region, including all of Harris, Fort Bend, Brazoria, Liberty, Montgomery, Galveston, Wharton, Waller, Austin, Chambers, Colorado, Matagorda and walker Counties. The STAR*Map data area is provided in a digital electronic GIS format known as a shapefile.
STAR*Map was created through a joint cooperative effort of the GDC member organizations, including more than sixty public and private partners. The map includes more than 2 million parcel address points, roadway centerlines, block address information, street names, street types, census geography and many additional feature attributes. Adopted by a number of local agencies (including City of Houston, TxDOT, Houston Metro and Harris County) as the "official" Harris County basemap, STAR*Map permits accurate overlay of many types of Geographic Information System (GIS) coverages, such as hydrology, bus routes, parcel-based data, utility data and other features mapped by the user community.
