Service Description:
High-resolution land cover dataset for the Chicago region: Cook County, DuPage County, Kane County, Kendall County, Lake County, McHenry County, Will County (IL), Lake County, LaPorte County and Porter County (IN).
Seven land cover classes were mapped:
0 - Background
1 - Tree Canopy
2 - Grass/Shrub
3 - Bare Soil
4 - Water
5 - Buildings
6 - Roads/Railroads
7 - Other Paved Surfaces
Class definitions and standards can be viewed at the link below.

Spatial resolution (pixel size) of the source dataset is 1 meter.
The primary sources used to derive this land cover layer were 2006, 2007, 2008, 2010, 2014 LiDAR data, 2010, 2012, 2013 NAIP imagery and 2010, 2013 Ortho imagery. Ancillary data sources included GIS data provided by each county or created by the UVM Spatial Analysis Laboratory. Object-based image analysis techniques (OBIA) were employed to extract land cover information using the best available remotely sensed and vector GIS datasets. OBIA systems work by grouping pixels into meaningful objects based on their spectral and spatial properties, while taking into account boundaries imposed by existing vector datasets. Within the OBIA environment a rule-based expert system was designed to effectively mimic the process of manual image analysis by incorporating the elements of image interpretation (color/tone, texture, pattern, location, size, and shape) into the classification process. A series of morphological procedures were employed to insure that the end product is both accurate and cartographically pleasing. Following the automated OBIA mapping a detailed manual review of the dataset was carried out at a scale of 1:6,000 and all observable errors were corrected.
