Washington Land Cover

The Washington Land Cover is a high-resolution (1 meter) data product that provides baseline land cover information for the state of Washington in multiple formats to support different land management applications. It is derived from 1 meter, 4 band color infrared imagery flown between June 23, 2015 and September 29, 2015 as part of the National Agriculture Imagery Program (NAIP). In addition LIDAR data flown between 2009 and 2015 was used to aid the classification process. Over 8 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.


Class NameValueClassification Description
Herbaceous1all surfaces with non-woody vegetation - lawns, cropland, grasses, etc.
Bare2non-vegetated non-impervious cover - snow, sand, barren farmland, rock, etc.
Impervious3impermeable built-up surfaces - roads and transportation infrastructure, sidewalks, buildings, parking lots, etc.
Water4open water - lakes, rivers, streams, sea, ponds, etc.
Shrubs6low woody vegetation - early stage or stunted trees

What can you do with the Washington Land Cover data?

The Washington Land Cover 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 Washington Land 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 2.6 billion image-objects were created from over 37,255 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 92.5%.
