What is the CGA?

The Center for Geospatial Analysis (CGA) was founded in 2008 as an interdisciplinary program at William & Mary to promote the use of geographic information systems (GIS) and associated tools. Today, the CGA is a vibrant center for W&M faculty, staff, and students, as well as the broader community, for all things related to mapping and the visualization of spatial data.

What can the CGA do for you?

With the support of grants from Mellon, NSF, and internal awards, we're able to provide access to common GIS and remote sensing (RS) software packages, including open-source alternatives. We also have mapping equipment, including handheld GPS units, map plotters, and large format scanners and printers. All of this is housed in our 2000ft2 lab on the 2nd floor of Swem Library. In addition to employing full-time faculty members with expertise in GIS and remote sensing, we also partner with faculty across campus who incorporate GIS into their research and teaching.

What is GIS?

A geographic information system (GIS) is a way to visualize, analyze, and display spatial data. GIS, with the aid of various software and hardware, allows scientists, researchers, policy makers, and others to better interpret and share their work. In brief, GIS is a tool to create and study maps for almost any purpose.
