- Abstract
- The analysis used to produce this dataset looks at geographic location, surface slope, surface aspect, and the effects of shading based on local topography and adjacent structures. A digital surface model was generated from raw LiDAR data. Then, using this DSM, an individual locations on a grid surface were assessed for the amount of direct and indirect radiation that reaches the surface. This analysis was conducted at a 1m resolution for the entire state of Minnesota.
- Purpose
- The Minnesota Solar Suitability Analysis attempts to provide solar insolation analysis for the entire State of Minnesota. As far as we are aware, it is the only project of its scale in existence; similar studies have been limited to metro areas or focus on rooftop insolation. The project's existence is feasible because of statewide, freely available aerial lidar coverage. And the commitment of the team to work long hours on this unfunded project. The project finds itself at the intersection of renewable energy, big data analysis, geospatial technology, and open data availability. This data provides a measure of incedent solar radiation as it is intercepted by the earth surface, or features (such as vegetation and buildings) standing above the earth surface. The data is intended to be used to assess the suitability of a site for solar panel (photovoltaic cell) installations.

- Data Quality Information
- Attribute Accuracy Report
- As of 29 June 2015, no groundtruthing has been done to assess the accuracy of the predicted WH/m^2 values.
- 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 Dept. 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).
