GIS (Geographical Information Systems) at Reed

What is GIS?

A geographical information system (GIS) is a computer-based combination of spatial data and other data, allowing analysis of spatial problems and potentially revealing patterns that are not obvious via tabular data alone.

For example, a GIS can help answer basic questions of site suitability (where is the best study area based on my criteria), look at data across space (is wealth equally distributed across Portland?), or more complicated questions (what is the best route to take, does proximity to a grocery store positively affect home resale value). 

GIS software options

There are two main GIS software packages used for spatial analysis: (1) the proprietary ArcGIS package from Esri dominates the GIS market (2) the free, cross-platform, open-source QGIS software, used worldwide.

See other help pages for more information on either the ArcGIS suite from ESRI or other, alternative software (including some spatial visualization tools).
