The Beta version of Whitebox Geospatial Analysis Tools, a new open-source GIS replacing TAS is now available for download. |
TAS GIS
Please note, although TAS GIS is currently still available for download, TAS is no longer being supported. Its replacement, Whitebox Geospatial Analysis Tools, is an open-source GIS and remote sensing package that offers many advantages over TAS.
The Rationale for TAS
Welcome to the Terrain Analysis System (TAS) homepage. As a hydrologist and geomorphologist, I was very discouraged by the lack of an affordable software package capable of advanced modeling of catchment processes. TAS is designed to meet the research needs of environmental modellers and managers while being simple enough to use in the classroom. Some geographic information systems (GIS) possess some of the capabilities required by hydrologists, geomorphologists, and other environmental researchers; however, these programs are usually prohibitively expensive. In addition, very few programs compile the number of functions available in TAS in one stand-alone package. Often, such programs rely on other GISs for visualization and standard spatial analysis. TAS can display both raster and vector types of geographic data, and possesses many of the standard spatial analysis function that the environmental modeller requires. The graphical user interface is designed with ease of use in mind. As such, TAS is ideal for lab exercises in introductory to advanced level courses in physical geography, geomorphology, hydrology, environmental science, and watershed management.
