What can you do with SpatialCover Impervious South Carolina?

The SpatialCover Impervious South Carolina dataset supports numerous applications for stormwater management, urban planning and for monitoring ecosystem changes.


EarthDefine used a Geographic Object-Based Image Analysis (GEOBIA) processing workflow to create the SpatialCover Impervious South Carolina dataset. Multiple ancillary datasets including transportation framework vectors, TIGER demographic data, hydrological, cadastral and terrain data were used along with color infrared aerial imagery to develop an object based classification workflow. Over 1.1 billion image-objects were created from over 20,369 square miles of 1m resolution source imagery and classified through our GEOBIA platform to create a 6-class classification with an overall accuracy of 96.2%. The SpatialCover Impervious layer was derived from the base SpatialCover Land Cover for South Carolina to prioritize the classification of man made impermeable surfaces.
