2007 Orthophotos. USDA National Agriculture Image Program (NAIP) natural color orthophoto mosaics from aerial photos taken in June - October 2007. The maximum resolution of this imagery is 2 meters. Imagery is provided by the Iowa State University GIS Lab. The red dot represents where we believe the sensors for the SchoolNet8 site to be located. For a majority of the sites, the red dot was the location of the GPS sensor during the site installation (often in the parking lot).
