In general, Google Earth elevation data can be used only for investigation and preliminary studies with low cost.

The obtained accuracies for terrain with small height difference can be used for preparing large area cadastral, city planning, or land classification maps. The results showed that the accuracies for the prepared DEMs are suitable for some certain engineering applications but inadequate to meet the standard required for fine/small scale DEM for very precise engineering study. The reference data was collected with total station survey. All these accuracy statistics were computed using the ground coordinates of 200 reference points for each region of the case study. The accuracy of the Google earth derived elevation data are reported using root mean square error (RMSE), mean error (ME) and maximum absolute error (MAE). The case study consisted of three different small regions in the northern beach in Egypt. This paper proposes a method of generating DEM by using Google Earth elevation data which is easier and free. There are several sources for this terrain, so let’s make sure we are using the highest quality one. This option drapes the imagery over a DTM (Digital Terrain Model). Look in the Layers box to ensure that there is a checkmark next to Terrain.

Moreover, DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally-produced relief maps. By default, GEP’s Terrain option is turned on for you. Contour lines, slope - aspect maps are part of their many uses. Google Earth Version Newer Google Earth versions may lose the connection to SoundPLANessential. Call edit -> Get terrain points from Google Earth the elevations of the selected viewport are imported and automatically mashed to a digital terrain model. Digital Elevation Models (DEMs) comprise valuable source of elevation data required for many engineering applications. relatively small projects in flat terrain.
