GIS for Mapping Waterfowl Density and Distribution from Aerial Surveys
Butler WI, Stehn RA, Balogh GR. 1995. GIS for Mapping Waterfowl Density and Distribution from Aerial Surveys. Wildlife Society Bulletin. 23(2):140-147
We describe a GIS (geographic information system) that combines a personal computer, a color printer, a color plotter, aerial survey data, software for programming, standard mapping, and 3-dimensional mapping. It allows us to display: (1) geographic locations of observations; (2) isopleths showing the distribution and relative density for each species or group of species; (3) changes in distribution; (4) changes in bird density; and (5) isopleth overlays on data layers such as land ownership. Our method of analyzing and graphically presenting waterfowl location data has increased the use, effectiveness, and application of multi-species aerial surveys in Alaska. These techniques should be equally useful outside Alaska.
