Welcome to the City of Galveston's GIS Online Maps Server. Here you will find tools to create your own maps. For example, you can find out where the City's parks are located or the type of zoning the lot next door to your home or business has. These applications have been developed by the City's Information Technology Services Department in coordination with the Planning and Community Development and Public Works Departments. Citizens and staff now have easy access to GIS data.

Over the next few months, the City will continue to add new GIS applications and downloadable data. Please check back often.
