California Impervious Cover
The California Impervious Cover product is a high-resolution (1 meter) dataset that provides information on built-up cover in California to support different stormwater management and ecological applications.
What can you do with the California Impervious Cover data?
The California 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 California 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 4.9 billion image-objects were created from over 158,123 square miles of 1m resolution source imagery and classified through our GEOBIA platform to create a 6-class classification with an overall accuracy of 93.5%. The Impervious Cover layer was derived from the base Land Cover data for California to prioritize the classification of man made impermeable surfaces.
