H-GAC GIS Dataset

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 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.

  1. Using a web browser, search for "h-gac gis" and select the result as shown below

COHGIS Open Data Portal

The COHGIS (City of Houston GIS) Open Data Portal website provides over 100 data sets including administrative boundaries, amenity locations, transportation routes, crime, and flooding. For this tutorial, we will download population and housing data from the 2010 census, which has been aggregated to super neighborhood boundaries.
