摘要：

We describe a CIS (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.
