The GIS Weasel: An interface for the development of geographic information used in environmental simulation modeling
Dataset Identification:
Resource Abstract:
The GIS Weasel is a freely available, open-source software package built on top of ArcInfo Workstation?? [ESRI, Inc., 2001,
ArcInfo Workstation (8.1 ed.), Redlands, CA] for creating maps and parameters of geographic features used in environmental
simulation models. The software has been designed to minimize the need for GIS expertise and automate the preparation of the
geographic information as much as possible. Although many kinds of data can be exploited with the GIS Weasel, the only information
required is a raster dataset of elevation for the user's area of interest (AOI). The user-defined AOI serves as a starting
point from which to create maps of many different types of geographic features, including sub-watersheds, streams, elevation
bands, land cover patches, land parcels, or anything else that can be discerned from the available data. The GIS Weasel has
a library of over 200 routines that can be applied to any raster map of geographic features to generate information about
shape, area, or topological association with other features of the same or different maps. In addition, a wide variety of
parameters can be derived using ancillary data layers such as soil and vegetation maps.
