Each post, often called a dataset, contains the elevation of the terrain at a Cited by: 1.

In principle, any data that contains the elevation informa-tion with location context can be a . Compute slope, aspect and other terrain characteristics from a raster with elevation data. The elevation data should be in map units (typically meter) for projected (planar) raster data. They should be in meters when the coordinate reference system (CRS) is longitude/latitude.

Next, create two elevation lines in the plan equal to the subfloor height above terrain value that was specified in the previous step: Select Terrain> Elevation Data> Elevation Line from the menu, then click and drag to draw an elevation line.; Click on the line to select it, then click the Open Object edit button.

On the Elevation panel of the Elevation Line. A digital elevation model (DEM) is a 3D CG representation of a terrain's surface – commonly of a planet (e.g. Earth), moon, or asteroid – created from a terrain's elevation data.

A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems, and are the most common basis for digitally produced relief maps. Global Multi-resolution Terrain Elevation Data (GMTED) By Jeffrey J. Danielson and Dean B.

Gesch Global Land One-km Base Elevation (GLOBE) model and other comparable arc-second-resolution global models, using the best available data. The new model is called the Global Multi-resolution Terrain Elevation Dataor GMTED for Size: 2MB.

These Digital Elevation Model (DEM) data files are produced by the U.S. Geological Survey (USGS) and provide coverage in 1 by 1 degree blocks with approximately 90 by 90 meter resolution for all of the contiguous United States, Hawaii, and limited portions of Alaska. Our new global elevation layer, Terrain-RGB, is live.

Encoded in the Red, Green, and Blue channels of these PNG tiles are raw height values in meters. You can use the elevation data stored within Terrain-RGB for a wide variety of applications both visual and analytical, from styling terrain slope and hillshades to generating 3D terrain for.

This new elevation data called Global Multi-resolution Terrain Elevation Data (GMTED), replaces the thirty year old GTOPO30 terrain model. GMTED is a suite of seven raster data products: minimum elevation, maximum elevation, mean elevation, median elevation, standard deviation of elevation, systematic subsample, and breakline emphasis.

GMTED – Global Multi-resolution Terrain Elevation Data The USGS has global DEM data at several resolution levels: arc-second (1 kilometer), arc-second ( meters), and arc-second ( meters). The GMTED dataset with multiple resolution levels replaces a former version called GTOPO30, which only had the resolution level of.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): ABSTRACT: Software tools have been developed at the U.S. Geological Survey’s EROS Data Center to extract topographic structure and to delineate watersheds and overland flow paths from digital elevation models.

The tools are special purpose FORTRAN programs interfaced with general. Global Multi-resolution Terrain Elevation Data (GMTED) (NGA) have collaborated to produce an enhanced replacement for GTOPO30, the Global Land One-km Base Elevation (GLOBE) model and other comparable arc-second-resolution global models, using the best available data.

The new model is called the Global Multi-resolution Terrain. this project, GIS software is used to perform a terrain analysis, which employs elevation data to characterize the physical features of the landscape.

Terrain analysis can be used to identify locations with a high potential for. during the 's in developing a terrain analysis data base which could be synthesized and manipulated by trained soldiers in order to produce meaningful and useful terrain products for commanders.

The result was the production of DMA's Tactical Terrain Analysis Data Base (TFADB) at a scale ofAccuracy assessment of the processed SRTM-based elevation data by CGIAR using field data from USA and Thailand and its relation to the terrain characteristics Y.
