The Solar Radiation Potential Model (SRPM) was derived from the Lake County 2007 Digital Surface Model (DSM). The DSM is a 3-foot pixel resolution raster in GeoTIFF format, created using all points (excluding NOISE) from our 2007 LiDAR data without incorporating the breaklines. The SRPM was created using the ArcGIS 'Area Solar Radiation' geoprocessing tool. Due to the number of variables and parameters, the default values of the geoprocessing tool were used.The solar radiation analysis tools in the ArcGIS Spatial Analyst extension enables one to map and analyze the effects of the sun over a geographic area for specific time periods. It accounts for atmospheric effects, site latitude and elevation, steepness (slope) and compass direction (aspect), daily and seasonal shifts of the sun angle, and effects of shadows cast by surrounding topography. The resultant outputs can be easily integrated with other GIS data and can help model physical and biological processes as they are affected by the sun.These data are derived from other data sources, no accuracy measurements or tests were conducted. Primary use and intent for these data are for visualizations and topographic analysis. This dataset does not take the place of an on-site survey for design, construction or regulatory purposes.
