I have push-pins at two locations in Google Earth version 7.1.5.1557 that I downloaded and installed on my MacBook Pro today. I’m told you can measure distances with Google Earth.
I click on the little Ruler icon and I get a pop-up window that says ‘Measure the distance between two points on the ground.’ I can change Map Length units and check or uncheck Mouse Navigation, but Save and Clear are greyed out and there are no other controls to measure a distance.
So how to you measure the distance between two points?
OK, I seem to have found it. You don’t actually do anything in the box. It just takes up screen space and gives you a number after you’ve figured out how to find the distance. I single-clicked on one push-pin and then single-clicked on the other one, and the distance appeared in the box.
Right-click on a spot and select “Measure distance”. Right-click on another spot and select “Distance to here”, and you get a ‘straight-line’ measurement.
I’ve used this method to try and ballpark acreage of known properties.
I know the edge of the (hypothetical) field is the property boundary to the east. The road is the north boundary. The creek to the south is straight enough to fudge. The west flanks the neighbor’s fence.
The (now free) Google Earth Pro lets you draw polygons and gives you the area, too.
Also about the “as the crow flies” measurements, I’m not sure about Maps, but Earth gives you both the “as the crow flies” distance through the air and the ground distance, taking into account elevation changes across hills and mountains. May or may not be important depending on what you’re doing.
