The Montana Spatial Data Infrastructure (MSDI) Imagery Framework layer relies on the imagery products produced by the National Agricultural Imagery Program (NAIP).



Digital Orthoimagery are georeferenced images of the Earth’s surface. Displacement of objects has been removed for sensor distortions and orientation and for terrain relief.

Many geographic features, including those that are part of the Framework, can be interpreted and compiled from an orthoimage. Orthoimages can also serve as a backdrop to reference the results of an application to the landscape.
