Land Use Inventory
CMAP periodically conducts a survey of the region's land use, publishing the results in GIS format as the Land-use Inventory. The inventory is an essential input to CMAP's land use and transportation research. Other users of the data include county planning departments, regional transportation agencies, federal & state agencies, university researchers, non-governmental organizations, environmental consulting firms and civil engineering firms.
The forecasting community focuses on broad land-use categories, but local officials, planners, and non-profit organizations can also benefit from having the data available at a greater level of detail. A deeper understanding is desirable both in terms of information ("single-family" and "multi-family," as opposed to simply "residential") and spatial resolution (acres instead of quarter-sections). CMAP's land-use inventory aims to fulfill these higher expectations.
The most current land use data available references the year 2005. Work is currently underway on a 2010 Land-use Inventory, which is scheduled for release in 2014.
CMAP's 2005 Land-use Inventory (Version 1.0) is available for download free of charge. The inventory was created using 2005 digital aerial photography, supplemented with data from numerous government and private-sector sources. The inventory covers Cook, DuPage, Kane, Kendall, Lake, McHenry and Will counties, identifying areas as small as one acre using a 49-category classification scheme.
Also available is our revised (Version 2.1) 2001 Land-use Inventory. Numerous small inconsistencies were discovered since its initial release, and this revised file is substantially more accurate. This file will be useful for any comparative studies with the 2005 Inventory.
The 2005 Inventory and the Revised 2001 Inventory can be downloaded from the CMAP FTP server in both ESRI shapefile and personal geodatabase (v9.3) format. The link to the data is below. You will be asked first to provide your name, the name of your organization, and an email address. The email address will be used only to contact you regarding further updates to the data, and will not be used for any other purpose.

Over 44% of the 4,071 square mile CMAP region is occupied by a developed land use. The following chart shows the breakdown of developed and other major categories by sub-region.
In the seven counties, construction activities were identified on over sixty square miles of area, with more than three-quarters of that area dedicated to residential construction. Sub-regional proportions of residential/non-residential activity are shown here.
