Service Description: Multi-resolution dynamic Image Service covering the Arctic at 2, 5 and 8 meters. These overlapping DEMs are generated by PGC from Digital Globe WorldView satellite imagery and are attributed with their acquisition date, so can be visualized temporally. The 8m DEMs will gradually and incrementally be replaced with 2m versions as they are produced during 2017. 5m mosaics created from the 2m data are also included.This service provides access to elevation values for use in analysis with server-side functions for slope, aspect, hillshade and contour. This service is in beta release. For more information on this service, including the terms of use, visit us online at ArcticDEM.
