Aerial imagery is available from the Property Appraiser.

The Orange County History Center has historical aerial photos.

The Orange County Public Works GIS staff has aerials going back to 1939, but in PDF not GIS format.

• Orthophoto imagery is aerial photography that has been processed to be spatially accurate. You can measure distances on orthophotos.

• Aerial photos that are not orthophotos are not spatially accurate. They are just pictures (sometimes very good ones) that are generally taken from airplanes. Generally, they cannot be overlaid successfully with GIS map data.

While we display a great deal of aerial imagery on our web site, we do not provide orthophotos or other aerial imagery in digital file format to the public. Imagery files are not available for download from our website or FTP server. We get most imagery from other sources and don't have the rights to distribute the digital files.
