Alternatively, delete the path from the Places dialog box. To delete an existing path, in normal view, right-click and select Cut. Tips: To delete a point while working on a path, right-click while in path mode. This file will contain the latitude, longitude, and elevation of each data point in the path, but it needs some manipulation in order to develop a contour map. Then use File > Save Place As and save (export) the data as a kml file (not kmz). Nothing appears to happen, but the path data is saved and visible in the box at left. Yours may not need to be so long.įirst, use File > Save My Places. It is a good idea to size the path dialog box so the display shows your entire site (and some extra) visible making sure that the path dialog box is out of the way.Īfter adjusting the path colour and units using the tabs in the dialog box, draw the path. Type a suitable name for the path in the name box. To create a path, from the ‘Add’ drop-down menu > select the Add Path option. The path will contain information on the x and y coordinates and also an elevation (z value) of each point you add. To create a contour map, it is necessary to use some Google Earth tools and add a path of points. Save the image using the option on the top toolbar. Take off (do not show) the various layers in the tools at left so no text displays. Use View > and make sure that the scale bar option is on. The keyboard shortcut “U” is a convenient way yo do this. Tip: We are going to ‘fly’ to the site and take the image, scale bar and other data so it is a good idea at this point to make sure that you have a top-down view. It is a site that’s about 0.7 hectares in area. Open Google Earth, type the address or KLM coordinates of the site, and ‘fly’ to your destination. 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.
