The Polar Geospatial Center
The Polar Geospatial Center is a research center at The University of Minnesota's College of Science and Engineering. Founded in 2007, the Polar Geospatial Center "provides geospatial support, mapping, and GIS/remote sensing solutions to researchers and logistics groups in the polar science community."  It is currently directed by Paul Morin.
The Polar Geospatial Center (PGC) was founded in 2007 and was originally called the Antarctic Geospatial Information Center (AGIC). In its early days, the AGIC's goal was to provide basic mapping and GIS services for the United States Antarctic Program (USAP), and was only a two man project. As time went on, the program's credibility and size expanded. By 2010, the program had over a half dozen team members. In March 2011, the program was "classified as a National Science Foundation cooperative agreement"  and adapted to take responsibility for Arctic as well as Antarctic operations, hence the name change to PGC.
The PGC's current goal is to support federally funded researchers in the Artic and Antarctic. The PGC utilizes geospatial and remote sensing technology to work with research teams and solve problems. Some specific examples of services are listed below.
Image Delivery & Analysis
The PGC has a large collection of both satellite imagery as well as aerial photography at various resolution. The PGC can process specific imagery for federally funded researchers, but most imagery is available for direct download from their satellite imagery page or aerial photography page. The PGC keeps records and photos for a variety of imagery programs.
Custom Map Requests
The PGC houses a large record of Antarctic and Arctic maps in digital form. These maps are from many different organizations and periods in time. Many of these maps are publicly available, some are not and may be provided upon request.
