ArcGIS • Largest Selling GIS Software Application • Broad support in many sectors • Expensive • Slow • Many Quality Issues • Not popular outside the US
There are lots of options • GRASS: Really hard to use • Quantum GIS: Not as hard to use • DIVA GIS: Easy, not as full featured • MapInfo: Marketing • Autodesk: CAD, Utilities • Intergraph: GeoMedia • IDRISI: Clark University • Smallworld: ?
Utilities • FWTools • Proj4 – Projectors (SRS conversions) • GDAL – Raster file format conversions • OGR - Vector file format conversions • EPSG • European Petroleum Standards Group • Database of SRSs • 7zip • Decompression
Modeling/Analysis Software • Geospatial Modeling Environment • Primarily Wildlife Modeling • Was Hath’s Tools • R • Free statistics package • Some spatial functions • SAGA • System for Automated Geoscientific Analysis • Free • IDRISI • Image processing and analysis
Vertical Applications • HEC-RAS: • Hydrologic Engineering Centers River Analysis System • Army Corp of Engineers • Fire: • BehavePlus • FlamMap • FARSITE • Others…
Arc Extensions • Hawth’s tools -> Geospatial Modeling Environment • Historically for modeling animal movement • Extensive feature set in a new language • Number of available extensions has decreased lately • Many “tools” are written internally to organizations • ArcMap 10’s main language for writing extensions is “Python”
