What does DEM stand for?

There is also the name of exits and streets so you never take your eyes off the road, and their 3-D digital elevation map gives you fair warning of the changed class.

Each section can be created and edited graphically, read from field data, or extracted from terrain data contained in a digital elevation map (DEM) or triangulated network.

The digital elevation maps show you shaded contours at higher zoom levels, so you a big picture of the surrounding terrain.

Some of the premier ADL collections include digital elevation maps and graphics of the United States, imagery from more than eight hundred expeditions by the Scripps Institution of Oceanography, and world maps from the United States Central Intelligence Agency.

By automating and streamlining time-consuming database creation tasks such as obtaining and processing imagery and digital elevation maps, creating and placing 3D objects (trees, shrubs, and buildings), classifying materials in the imagery, and generating run-time databases, EarthScape 3D reduces the cost and time required to produce databases with high image content.

TRW built the electro-optical camera that will provide cartography data for developing digital elevation maps of the Korean peninsula for land use and planning purposes.

Our marketing efforts are well received by customers in our preliminary test markets, and I look forward to tremendous industry acceptance once our inexpensive, accurate digital elevation maps (DEMs) are widely available".
