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.
