The service provides a repository of aerial photos and topographic maps of terrain within the U.S. state of Minnesota. Photographs are taken from aircraft to capture surface features, and topographical maps are scanned from authoritative printed versions. The Web Map Service (WMS) stores and provides access to very large image files, saving the need to download and save local copies.
API methods support access to digital orthophotography and hillshade images as well as scanned USGS quadrangle topographic maps for locations in Minnesota specified by latitude and longitude or UTM zone. Returned data compliant with WMS protocols provide links to image files in jpeg and png formats.
