Connecticut Land Cover

The Connecticut Land Cover is a high-resolution (1 meter) data product that provides baseline land cover information for the state of Connecticut in multiple formats to support different land management applications. It is derived from 1 meter, 4 band color infrared imagery flown between July 3, 2016 and August 3, 2016 as part of the National Agriculture Imagery Program (NAIP). Additionally statewide LIDAR data flown in 2016 was used to aid the classification process. Over 2 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 Connecticut Land Cover data?

The Connecticut 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 Connecticut 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. LIDAR data was used to develop the tree class and derive buildings that were added to the impervious class. Over 286.2 million image-objects were created from over 5,033 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 96.5%.
