AREOGRAPHY-2.0 - A PROGRAM TO DELIMIT DISTRIBUTIONAL AREAS OF SPECIES

AREOGRAPHY is a computer program that offers quick and efficient metho ds to summarize geographical information of spatial point data on a di stributional area map. By running this program, users can apply four m ethods for range compactation: mean propinquity, circular propinquity, grid method and minimum convex polygon. AREOGRAPHY 2.0 can also const ruct the minimum spanning tree between points. Animal ecologists can a lso use AREOGRAPHY 2.0 to fit home ranges. Maps can be overlapped and approximate areas can be calculated. Exact localities can be determine d on maps by using the coordinates mapping option. Data files can be e dited, imported from ASCII format, randomly created, and can include u p to one thousand individual data. (C) 1997 Elsevier Science Ltd.
