Composite Image Service for Minnesota
MnGeo’s Composite Image Service provides a single layer image
service that automatically switches to an appropriate set of air photos or satellite imagery
depending on the scale and extent. The images are provided as a WMS (web map
service). The primary focus is the Twin Cities Metropolitan Area
and the State of Minnesota. The secondary interest is the areas
bordering Minnesota, especially Wisconsin counties close to the metro area.
Imagery is evaluated based on criteria of color, currency, resolution, coverage, season, leaf cover and image quality in order to determine which imagery to include at which scale.
The url for users to paste into their software, or for developers to
access the WMS service is:

Imagery Visible at Different Scales
The layers higher in the list will show through in areas not covered by layers further down. For example, Landsat will continue to be displayed across bordering states where the FSA 2015 data does not extend.
