GIS was used to quantify changes to nearshore marine habitats and habitat functions resulting from historic anthropogenic changes such as dredging, filling, diking, and shoreline armoring. Allison assembled existing GIS data layers for current conditions including shoreline, bathymetry soundings, marine vegetation, fisheries habitat surveys, dredged areas, and artificial shoreline substrate. Current and historical bathymetry soundings were converted to surface models in both Tin and Grid formats. She performed GIS overlay analysis of the shoreline, bathymetry, natural resource and impact data to quantify the changes by depth strata. In addition, Allison developed batch mapping programs in VBA for ArcGIS to create a map series for the report.
