Peter Becker, ArcGIS product manager, Esri, talked with GISCafe Voice this week about the ArcticDEM project, that recently released the largest addition of new elevation models to the project. An ongoing collaboration effort between the National Geospatial-Intelligence Agency (NGA), the Polar Geospatial Center (PGC) and Esri, the ArcticDEM project produces high resolution elevation models to support the national security and scientific requirements of the Arctic. It also serves as a public data model that can be used by scientists to assess and augment climate change models. The NGA presented the new ArcticDEM elevation data the twentieth annual Esri Federal GIS (FedGIS) Conference, held February 13 and 14 at the Walter E. Washington Convention Center in Washington, DC.
