Grid-based modeling for land use planning and environmental resource mapping

摘要

Geographic Information System (GIS) technology is used by land managers and211u001enatural resource planners for examining resource distribution and conducting 211u001eproject planning, often by visually interpreting spatial data representing 211u001eenvironmental or regulatory variables. Frequently, many variables influence the 211u001edecision-making process, and modeling can improve results with even a small 211u001einvestment of time and effort. Presented are several grid-based GIS modeling 211u001eprojects, including: (1) land use optimization under environmental and regulatory 211u001econstraints; (2) identification of suitable wetland mitigation sites; and (3) 211u001epredictive mapping of prehistoric cultural resource sites. As different as the 211u001eapplications are, each follows a similar process of problem conceptualization, 211u001eimplementation of a practical grid-based GIS model, and evaluation of results.
