The CDEM is part of Natural Resources Canada's altimetry system designed to better meet the users' needs for elevation data and products. … The CDEM plays the same role as contours and relief shading on conventional paper maps. The CDEM serves as key primary data in a range of applications critical to achieving sustainable development. These applications include environmental and ecological impact assessments, water flow and water quality analysis, climate change studies, forest regeneration planning and wildlife habitats. In addition, the CDEM can be used in the generation of three-dimensional graphics displaying terrain slope, profiles and lines of sight. Non-graphic applications include geoid calculations, terrain modelling, flood simulations and telecommunication studies"--Overview, page 1. Digital elevation models Canada.
