USE OF A GEOGRAPHIC INFORMATION-SYSTEM TO FACILITATE ANALYSIS OF SPOT-MAPPING DATA

Spot mapping is widely used in bird research, but the time required to compile species composite maps and the limited utility of paper maps are a drawback to its use. A Geographic Information System (GIS) was u sed to enter and analyze spot-mapping data. A new program (BIRDMAP) wa s written using the programming language of PC ARC/INFO to digitize da ta from field maps. Use of BIRDMAP greatly reduced the time required t o produce species composite maps. Specific applications and benefits o f using a GIS for analysis of spot-mapping data are presented.
