Geographic Information Systems (GIS)

The GIS Division provides support and assistance to citizens, developers, and city staff with a variety of geographic maps and exhibits.

Visit our GIS Web App, where you can customize, view and print area maps with specific information such as property lines, flood plains, council districts, and background basemap options like topographic, 2016, or 2020 H-GAC imagery, etc. There is a print option for generating a custom map.


Looking for an overview or demo? Check out this story map 'How is GIS Technology used in the City?' from GIS Day November 17, 2021.
