Polar Geospatial Center

<h3 class="red">Polar Geospatial Center</h3><p>The Polar Geospatial Center (PGC) provides geospatial support, mapping, and GIS/remote sensing solutions to researchers and logistics groups in the polar science community. The Center collaborates with scientists to complete their research goals in a safe, timely, and efficient manner by providing expertise and access to geospatial data and derived products. While scientists have developed elevation models over most of the earth from varied sources, the Polar Regions lack even coarse resolution digital elevation models (DEMs). This dearth of data severely limits the potential for topographic analysis in hydrology, ecology, geology, and geomorphology, and greatly reduces the accuracy of satellite imagery. Using two algorithms developed by NASA Ames and the Byrd Polar Research Center at the Ohio State University, PGC is leveraging the high volume of stereoscopic imagery being acquired in polar areas to create high resolution DEMs for distribution to the polar science community. Preliminary tests and data distribution suggest that the science community both needs and is ready to utilize such DEMs for synoptic mapping and change detection .</p><p>Return to this PI&#39;s <a href="https://www.msi.umn.edu/pi/a600f247ed0c3a82e8ca794c48b53e5b/10469">main page</a>.</p>
