The Houston-Galveston Area Council (H-GAC) is the 13-county Metropolitan Planning Organization (MPO) for the Houston region. Federal legislation requires that an MPO be designated for each urbanized area with a population greater than 50,000 people (as established by the U.S. Census Bureau) in order to conduct long-range metropolitan transportation planning and be eligible for Federal funding for transportation projects. Their mission to conduct carry out metropolitan transportation planning , means that MPOs are a great source of data on topics such as demographics, employment, land use, transportation, and environmental conditions and most of these topics are well-suited towards GIS analysis.
Most of the data provided on the H-GAC portal is not originally created by the H-GAC, but rather is either aggregated from multiple municipalities up to the 13-country region, or clipped from the country or state down to the 13-county region.
