GEOGRAPHIC INFORMATION
SYSTEMS:
Mapping ecological data
Archbold Biological
Station maintains a fully equipped Geographic Information Systems (GIS) Laboratory using ARC/INFO Software. ARC/VIEW
software is available at all individual laboratories and at the Stations remote
sites. The GIS Lab computer system is fully integrated with the Stations LAN
operating with Windows NT. Original equipment and software for the GIS system was acquired
in fall 1990 with support from the National Science Foundation's Division of
Instrumentation and Resources, and has been updated several times to its current
configuration.
GIS opens the door to analysis and portrayal of
spatially referenced data. Maps are stored as digital data in the form of points, lines,
grid cells, and polygons.
GIS provides scientists at Archbold with powerful
capacity to store, combine, analyze, and map ecological data across space and time.
Dominant themes available for study by GIS at the Station include topography, soil types,
vegetation zones, fire boundaries, rare plant distributions, animal territories and nest
sites, and experimental trapping grids. Ranch GIS themes exist for topography,
vegetation
zones and wetlands, and raptor habitat use. Station and Ranch management are greatly aided
by the mapping capabilities and database structure of GIS. Virtually all long-term
ecological projects at the Station make use of this vital technological advance
