SpatialCover Land Cover Illinois

SpatialCover Land Cover Illinois is a high resolution (1 meter) land cover data product that provides baseline land cover information for the state of Illinois in multiple formats to support different land management applications. It is derived from 1 meter, 4 band color infrared imagery flown between August 1, 2015 and September 24, 2017 as part of the National Agriculture Imagery Program (NAIP). In addition LIDAR data flown between 2008 and 2014 was used to aid the classification process.

What can you do with SpatialCover Land Cover?

The SpatialCover Land Cover Illinois 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 Illinois 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 315.8 million image-objects were created from over 4,797 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 94.6%.
