You can measure the approximate acreage of a plot of land using Google Earth. Once you find the land or location you want to measure, you can bring out the built-in ruler and measure a portion of it. This only works on the Google Earth program on your computer, as the mobile app doesn’t have this feature.
Measure distances and areas in Google Earth You can measure distances between locations and along paths. You can also measure the size of polygons that you draw in Google Earth. Notes: Measurements may not be 100% accurate, especially in areas with 3D terrain and buildings. For best results, measure using a top-down view.
The good news is there is a way to measure your roof in a safe and accurate way, all from the comfort of your home: use Google Earth. With just a few clicks, you can search for any address, get a bird’s eye view of your roof, and get the roofing measurements that you need.
Apparently, the measurment ruler is not accurate over long distances > 5,000 km. Google’s offical stance says, “makes no claims as to the accuracy of the coordinates in Google Earth. These are provided for entertainment only and should not be used for any navigational or other purpose requiring any accuracy whatsoever”. Show activity on this post.

How accurate is Google Earth?
These academic researchers say: A horizontal position accuracy of 2.64 m RMSE r was determined for the Google Earth terrain model with mean offset distance being 6.95 m. A vertical position accuracy of 1.63 m RMSE z with mean offset distance of 2.66 m was also calculated for the terrain model.
This is why Google has that disclaimer about accuracy: Google makes no claims as to the accuracy of the coordinates in Google Earth. These are provided for entertainment only and should not be used for any navigational or other purpose requiring any accuracy whatsoever.
Another query we ran across in our research was “How accurate are google earth coordinates?”.
Google Earth now hosts high-resolution imagery that spans twenty percent of the Earth’s landmass and more than a third of the human population. Relative to Landsat Geo. Cover, the 436 Google Earth control points have a positional accuracy of 39.7 meters RMSE (error magnitudes range from 0.4 to 171.6 meters).
Well, however, Google Earth improved the results by using (in house) interpolation algorithms to mix and mesh SRTM data with other data in order to derive accurate results for these area. The accuracy of SRTM Data can range from 5 to 10 meter, depending on where you are. In Malaysia, the vertical accuracy ( both absolute and relative) stands at between.
Buyers sometimes use Google Maps to find the longitude and latitude of the corners of parcels that they are considering purchasing. But exactly how accurate are those estimates ? Google makes no claims as to the accuracy of the coordinates in Google Earth.
How to measure 3D buildings in Google Earth Pro?
3D polygon : The height, width, and area of 3D buildings. Go to a spot on the globe. In the menu bar, click Tools Ruler. A new “Ruler” window with options appears. In the bottom left, select Mouse Navigation. Click the tab for what you want to measure.
What is the horizontal coordinate accuracy of GPS?
Results from GPS method, a horizontal coordinate accuracy of 1 cm has been achiev ed by compensating for a tmospheric delay, orbital errors and other variables i n GPS geometry. According to Lin, (2004), accuracy test was made between GPS and total station. The results showed that a positional accuracy positional accuracy.
How accurate is GPS?
GPS Error – Even though GPS units give positions to a precision eight decimal places in latitude and longitude, corresponding to an accuracy of about a millimeter or so, the true accuracy with which you can measure a position with GPS is far poorer than that.
