The STAR*Map is a regional base map created by the Geographic Data Committee (GDC) in 1996 using TIGER centerlines referenced to a base map from Reliant Energy/HL&P. It has grown to include over 2 million address points, 400,000 road segments, and 260 polygon zip codes. STAR*Map is continuously updated daily by H-GAC GIS analysts using data from various regional sources and is used by governments, private sector agencies, educational institutions, and consulting firms for emergency response, transportation planning, and other purposes.
