Massachusetts Impervious Cover
The Massachusetts Impervious Cover product is a high-resolution (1 meter) dataset that provides information on built-up cover in Massachusetts to support different stormwater management and ecological applications.
What can you do with the Massachusetts Impervious Cover data?
The Massachusetts 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 Massachusetts 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 396.1 million image-objects were created from over 8,088 square miles of 1m resolution source imagery and classified through our GEOBIA platform to create a 6-class classification with an overall accuracy of 96.7%. The Impervious Cover layer was derived from the base Land Cover data for Massachusetts to prioritize the classification of man made impermeable surfaces.
