What is GIS?
A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.
A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.
GIS technology can be integrated into any enterprise information system framework.

Notes on COHGIS 2011:
The compressed files on the right contain most COHGIS administrative boundaries, locations, and routes.
All COHGIS layers are in ESRI Personal Geodatabase format.
Cadastral/parcel related datasets are not available for download from this website. GISTD no longer maintains the COHGIS parcel dataset. We now use appraisal district parcel datasets. All administrative boundaries, locations, and routes have been (or will be) adjusted to Harris (some Fort Bend and Montgomery) county appraisal district geographic parcels. All feature classes come with metadata.
HCAD parcel shapes and ownership tables can be downloaded from Harris County Appraisal District's Public Data at http://pdata.hcad.org.
If you have any questions, please contact us at cohgis@houstontx.gov. Thank you.
