Unlike a laptop, which is portable, a desktop computer is meant to stay at one location. Desktop computer overview. Below is a picture of a computer with each of the main components that help make up a computer. In the picture, you can see the Desktop computer, Flat-panel display, Speakers, Keyboard, and Mouse.
GLOBE [http://www.ngdc.noaa.gov/mgg/topo/globe.html] is also a global digital elevation model (DEM) with a 1 kilometer resolution. This project was headed by the Committee on Earth Observation Satellites. File Format: Binary Raster File *.dem Importing into ArcMap 1. In Windows Explorer navigate to the directory which contains the dataset (.dem) file
Many DEMs provided by the USGS use a 30-m grid. In other words, the area covered in the DEM is split into squares with 30-m sides. Hills or valleys smaller than the 30-m cells will not show up. In an effort to improve the data available for the Lake Tahoe region, the USGS Western Geographic Science Center has created a set of DEMs with 10-m cells. These 10-m DEMs come from the same source data, the hypsographic DLGs, which have 40 ft contours. No new elevations have been included, but elevation information has been interpolated to a finer resolution. For more information about DEMs, please visit http://craterlake.wr.usgs.gov/dem_brief.html.
