Organisation/s that developed the tool and country of origin
Country where the tool was produced: USA

Organisation and author/s that produced the tool:
The LEAM Model, its development, and its application to several regions within the continental United States is conducted and managed by a team of faculty, staff, and students at the University of Illinois at Urbana-Champaign, USA. This team brings together expertise in substantive issues, modelling, high-performance computing, and visualization coming from the departments of Landscape Architecture, Urban Planning, Geography, Economics, Natural Resources and Environmental Sciences, the National Centre for Supercomputing Applications (NCSA), the United States Army Corps of Engineers, and private industry.

Organisations/ departments also involved in the design/development of the tool:
A pilot test of its capabilities was conducted in Kane County, a fast-growing area northwest of Chicago. Following this the model application was refined for use at township level and entire county-scaled scenarios. The first full-scale use of the model was in the Peoria area, with assistance from state agencies that make up the Governor’s Balanced Growth Cabinet. Work in the St. Louis metro east area – on the Illinois side of the Mississippi River – began recently; researchers hope soon to receive the green light from the Metro west side to move forward with an integrated model for the entire region.

Organisation/s funded development of the tool:
LEAM originally was developed with support from a National Science Foundation grant in 1999
