The ruler tool will give you an azimuth to use to aim the device and the line will help you identify landmarks to assist in aiming. Use the Ruler tool’s 3D Path option to make sure your ladder is tall enough to reach the roof:ĭraw a line from the customer’s home to your tower and take the image with you to the install.
#Earth and the ruler tool install
Use Google Earth to prep for a customer install before you go on site. When the viewshed completes the areas on the map that have line of sight to the placemarker will be highlighted in green.
A pop-up may ask to adjust the height of the marker - select ‘Adjust Automatically’. Drop a placemarker, right click on it, and select ‘Show Viewshed’. Useful for determining line of sight, especially for longer shots over uneven topology.Ī viewshed will highlight all areas on the map that are visible from a specific point. This will show you a graph with the elevation of the ground beneath the line. Right click on a line and select ‘Show Elevation Profile’. If you want to learn more about KMLs checkout our What is Keyhole Markup article Elevation Profile Back in Google Earth open the modified KML file.Change one or both of them to match the height of the buildings. You’ll see both ends of the line in the ‘coordinates’ section - the first two numbers are the latitude and longitude and the third is the height above ground. Open the file in your favorite text editor (I use Atom).Save the file somewhere you can find it.Make sure to change the file type to KML (by default it will be KMZ).Right-click on the line and select ‘Save Places As’.Find the line in the left panel Places pane (it will be called ‘Line Measure’ unless you changed the name).Create a line between two points like in the section above.Unfortunately there’s not a way in the Google Earth interface to configure different heights on either end of the line, but there is a workaround: Sometimes you need to check the line of sight between two buildings that have very different heights. Notice it’s going right through a large tree - no line of sight this time! Set the Altitude to the height of the structures in meters (are the structures significantly different heights? See Lines with different heights below.).Change ‘Clamped to Ground’ to ‘Relative to Ground’.Go to the ‘Altitude’ tab on the line properties.This will give you a line between the two points. The ruler tool will show you the distance and the azimuth between the two points.Use the ruler tool to measure the distance between the two points.You can use the measure distance tool and the line draw tool to check line of sight between 2 points on Google Earth. To do that you’ll use a Batch Geocoding service.
Sometimes you have a list of addresses you’d like to get imported as placemarks to view on Google Earth.
