GIS Data Catalog

The GIS Data Catalog lists all the published GIS data that is in our database. Layers that say "Yes" in the Download column are available to the general public free of charge. Click on the link to download your file.

If you want a large quantity of data such as the aerial photography, you can also request the data on DVD or on an external hard drive. There is a charge of $24 for DVD and $225 for a hard drive. The $225 charge includes a 500 Gb hard drive that is yours to keep. Note that this service does not provide access to additional layers. Only those layers that are already available to the public can be requested on a hard drive.

If you want data on DVD/hard drive, click the comments links below and be sure to indicate the data layers you want in the Comments section. Make sure you include your contact email, as well.

Please send us your comments and rate the Data Catalog.
