SpatialCover Land Cover North Carolina

SpatialCover Land Cover North Carolina is a high resolution (1 meter) land cover data product that provides baseline land cover information for the state of North Carolina in multiple formats to support different land management applications. It is derived from 1 meter, 4 band color infrared imagery flown between May 17, 2014 and September 24, 2016 as part of the National Agriculture Imagery Program (NAIP). Additionally LIDAR flown in 2014 was used to aid the classification process. Over 14 terabytes of LIDAR and aerial imagery were processed for the state through EarthDefine's high performance Geographic Object-Based Image Analysis (GEOBIA) processing platform to create the land cover layer.

What can you do with SpatialCover Land Cover?

The SpatialCover Land Cover North Carolina dataset supports numerous applications for urban planning, forest inventory, stormwater management, environmental impact assessment and conservation.


Approach

EarthDefine used a Geographic Object-Based Image Analysis (GEOBIA) processing workflow to create the SpatialCover Land Cover North 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. LIDAR data was used to develop the tree class and derive buildings that were added to the impervious class. Over 1.2 billion image-objects were created from over 24,513 square miles of 1 meter resolution source imagery and classified through the GEOBIA platform to create a 6-class classification with an overall accuracy of 94.0%.
