Data Analysis System for Triangulation and Home Range


Joel Sartwell, Missouri Department of Conservation, 1110 South College Avenue, Columbia, MO 65201 USA

We are developing software to support and enhance the process of data reduction for triangulation and home range analysis. This Windows-based, highly-graphical, system imports and incorporates GIS (map layers) from a wide variety of spatial data formats: ArcView Shape, MapInfo Vector, AutoCad DWG, TIFF Image, Windows BMP, etc. Telemetry fixes, individual sightings, and internally generated location or home range estimates are then stored graphically as dynamic data overlay layers on top of the base map(s). A large variety of coordinate systems are supported and coordinate conversion is available. Northing and Easting positions are displayed and updated as cursor scrolls across the map. Data entry and storage are handled through separate database systems. The software is designed for real-time field use on laptops or portable computers. Map display controls include, zoom in, zoom out, center, add text, add line, and add polygon. Location estimators currently include: maximum likelihood, Huber m-estimator, and Andrew's m-estimators. Home range estimators will include: minimum convex polygon, Jennrich-Turner ellipse, Dixon-Chapman (see Analysis of Wildlife Radio-Tracking Data, by White and Garrott, Academic Press, 1990).
