EQPT: Ecological Quality Profiling Tool
Track: Ecology, Archaeology, and Conservation

EQPT uses "Habitat Value Units" to assess the ecological quality of selected areas. A Habitat Value Unit is equal to one unit area of pristine or desired habitat. The proximity of waste reduces the value of the habitat. The GIS uses a proximity-based iterative algorithm to aggregate similarly classified waste sites. A variable-size buffering algorithm is then used to approximate the effects of the waste on the environmental quality of the surrounding areas. The user-designated areas are analyzed, and the resulting quality profiles are presented quantitatively in tabular summaries and graphically as grids on a vector basemaps.
