Geographic information software is used to capture, analyze and present spatial or geographical data.
How to access GIS software:
See Analysis and spreadsheet tools for information on:
Commonly referred to as GRASS (Geographic Resources Analysis Support System), this is a free and open source Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling, and visualization. GRASS GIS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. It is a founding member of the Open Source Geospatial Foundation (OSGeo).
Whitebox Geospatial Analysis Tools (University of Guelph)
Whitebox GAT is an open-source desktop GIS and remote sensing software package for general applications of geospatial analysis and data visualization. It is intended to provide a platform for advanced geospatial data analysis with applications in both environmental research and the geomatics industry more broadly.
Orfeo ToolBox (OTB) is an open-source project for state-of-the-art remote sensing. Built on the shoulders of the open-source geospatial community, it can process high resolution optical, multispectral and radar images at the terabyte scale.
The MapWindow GIS project includes a free and open source desktop geographic information system (GIS) with an extensible plugin architecture; a GIS ActiveX control; and C# GIS programmer library called DotSpatial. ILWIS is good at the basics – digitizing, editing, displaying geographic data.
Integrated Land and Water Information System (ILWIS)
A remote sensing and GIS software which integrates image, vector and thematic data in one unique and powerful package on the desktop. ILWIS is good at the basics – digitizing, editing, displaying geographic data.
FalconView 5.1 (Developed by Georgia Tech Research Corporation (GTRC)
FalconView is a Microsoft Windows based mapping application that displays various types of maps and geographically referenced overlays. Many map types are supported, but the primary ones of interest to most users are aeronautical charts, satellite images, and elevation maps. FalconView also supports a large number of overlay types that can be displayed and printed over any map background
GeoDa (developed by the Center for Geospatial Analysis and Computation at Arizona State University)
GeoDa is an open source software tool that serves as an introduction to spatial data analysis. It is designed to facilitate new insights from data analysis by exploring and modeling spatial patterns.
