![]() ![]() Step 1: Add a path to a Google Earth view The figure below shows a base map developed from Google Earth data.Ī description of the steps taken when developing the site and contour map shown above using Google Earth data follows. The accuracy of the map is of course limited by the resolution of the satellite image, but useful data can certainly be obtained. This movie show step by step how to extract 3D information from Google Earth, transform the data into a set of x,y and z coordinates, export data to Excel, create a contour map in QuikGrid, and export to gCADPlus. As an alternative, it is possible to extract 3D information from Google Earth and, using other software tools, make a contour map of the site with certainly enough contour information to produce a concept design. It is expensive to employ a team of surveyors to produce what will be a very accurate base map. Get contour data from Google Earth and produce a contour map to develop a landscape plan for a site, no matter what the size.
