The South Carolina Impervious Cover product is a high-resolution (1 meter) dataset that provides information on built-up cover in South Carolina to support different stormwater management and ecological applications.

The South Carolina Impervious Cover 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 South Carolina Impervious Cover 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 Impervious Cover layer was derived from the base Land Cover data for South Carolina to prioritize the classification of man made impermeable surfaces.
