I'm developing a diagramming tool using aerial imagery as a reference layer. This tool should allow the user to zoom in quite close to a roadway or intersection. Unfortunately none of the public map services I have tested supports zooming in close enough. Are there subscription map services out there that have imagery with resolution high enough to zoom in quite close to the roadway?
The USGS seems to have 1ft imagery for all (most, many) of Florida's counties. They are available via WMS from http://imsortho.cr.usgs.gov/WMS_Capabilities/USGS_EDC_Ortho_Florida/capabilities_1_1_1.xml?SERVICE=WMS&VERSION=1.1.1&REQUEST=getcapabilities
There also is the ImageConnect service from Digital Globe. Spot Image is also preparing a similar service, SPOTMaps online, but I couldn't find a reference yet. Both are, will be, available as WMS.
You can purchase aerial photos of the entire state of Florida here:
Beverly Renard Technology Specialist FREAC/Florida State University C2200 University Center 296 Champions Way P.O. Box 3062641 Tallahassee, FL 32306-2641 850-644-2305 850-644-7360 fax
That will get you over 300 GB of MrSID files. Then you need to setup the infrastructure to serve those images.
