Data Quality Information
Attribute Accuracy Report
As of 29 June 2015, no groundtruthing has been done to assess the accuracy of the DSM.
Logical Consistency Report
Visual assessments have been made to the data to assure that they meet expected results. Due to variation in input data including differing collection methods and data collection specificationsm, significant variation can be found in the quality of the output generated. Prior to use, a thorough inspection of the region of interest should be made to ensure that it is free of anamolies or inconsistancies. Examples of data anomolies and errors can be found at the project website (solar.uspatial.umn.edu).
Completeness Report
The input data used for development is lidar data collected by the State of Minnesota Department of Natural Resources in cooperation with a number of other local, regional and federal agencies and organizations. These data collects have been aggregated for the state of Minnesota and distributed to the public by the Minnesota Geospatial Information Office (www.mngeo.state.mn.us).
