New GIS Hub Coming Soon!
We are excited to announce our new GIS Open Data Portal hosted via ArcGIS HUB. Check this announcement for future updates and details.
GIS Data Catalog
The GIS Data Catalog lists all the publicly accessible data. 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 an external hard drive. There is a charge of $225 for a hard drive. The $225 charge includes a USB hard drive that is yours to keep. Note that this service does not provide access to additional layers.
If you want data on USB 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 or questions about the giscatalog.
