SpatialCover Land Cover Wisconsin
SpatialCover Land Cover Wisconsin is a high resolution (1 meter) land cover data product that provides baseline land cover information for the state of Wisconsin in multiple formats to support different land management applications. It is derived from 1 meter, 4 band color infrared imagery flown between September 14, 2015 and September 20, 2015 as part of the National Agriculture Imagery Program (NAIP). In addition LIDAR data flown between 2010 and 2015 was used to aid the classification process. Over 1 terabyte 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.
|Class Name||Value||Classification Description
|Herbaceous||1||all surfaces with non-woody vegetation - lawns, cropland, grasses, etc.|
|Bare||2||non-vegetated non-impervious cover - snow, sand, barren farmland, rock, etc.|
|Impervious||3||impermeable built-up surfaces - roads and transportation infrastructure, sidewalks, buildings, parking lots, etc.|
|Water||4||open water - lakes, rivers, streams, sea, ponds, etc.|
|Shrubs||6||low woody vegetation - early stage or stunted trees|
What can you do with SpatialCover Land Cover?
The SpatialCover Land Cover Wisconsin dataset supports numerous applications for urban planning, forest inventory, stormwater management, environmental impact assessment and conservation.
EarthDefine used a Geographic Object-Based Image Analysis (GEOBIA) processing workflow to create the SpatialCover Land Cover Wisconsin 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 29.2 million image-objects were created from over 310 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 94.3%.
