ArcGIS

ArcGIS is a complete system for authoring, serving, and using geographic information. It is an integrated collection of GIS software products for building and deploying a complete GIS wherever it is needed—on desktops, servers, or custom applications; over the Web; or in the field.

ArcGIS 10.1 is now available.  Please contact request@ldeo.columbia.edu for licensing information for usage at Lamont-Doherty Earth Observatory.
