For demonstration purposes, the approach is demonstrated for a multi-county area around Fort Benning, GA.Įngineer Research and Development Center Geotechnical and Structures LaboratoryĬonstruction Engineering Research Laboratory Army Corps of Engineers, P.O. PEWL includes both the source and executable files of the FORTRAN programs. PEWL was developed in FORTRAN language on Microsoft™ Developer Studio (FORTRAN PowerStation 4.0, 1993-1994) software. The generated analysis programs from PEWL are executed using SAS, a common statistical package, to complete logistic estimation. PEWL consists of computer programs to prepare samples, generate programs for regression analysis, and produce data files (estimated weights) for simulation using the Urban Sprawl Submodel of LEAM. The Procedure for Estimating the Weights of LEAM (PEWL) uses logistic regression techniques and historic land use data to statistically calibrate the 13 subfactors used in LEAM. Microsoft Fortran Compiler Full Visual Studio. The model uses physical and social factors to simulate the dynamics of urban development. This development nvironment provides everything ncessary to edit, buiId and debug Frtran applications. Popular downloads for software development tools.

The LEAM model is used to predict urban growth and environmental impacts associated with urban growth. Simply Fortran is a complete Fortran solution for Microsoft Windows and compatible operating systems. This document describes spatially explicit methodology to calibrate the Land use Evolution and impact Assessment Model (LEAM) using historic land use data.
