You can create an account to save your measurements and browse them later on. Tip: To move a point or path, click and drag it. At the bottom, you can find the total distance in miles (mi) and kilometers (km). To add another point, click anywhere on the map. The last location search result will be displayed at the next application startup.ġ0. To create a path to measure, click anywhere on the map. You can remove each marker in marker details window.ĩ. You can tap on each marker to see the details.Ĩ. You can move markers using your finger to adjust them to a specific position.ħ. Viewfinder can be turned on/off using the viewfinder button from the top menu.Ħ. You can change the map type: hybrid (satellite image with street names)/satellite/road.ĥ. You can change also the metric system: meters/miles.Ĥ. From the Settings menu you can change the type of measurement – area/distance.ģ. If you press the Settings button you can customize the application behavior.Ģ. The distance/area calculation result will be displayed in the left top corner of the screen.ġ. They may represent your route in case of distance measurement or the boundary of your estate in case of area measurement.ģ. Use the red marker form the top menu to add many markers on the map. in the world and it will be displayed in the center of the map.Ģ. Search option allows you to just type the name of any city, street, landmark etc. Find the location on the map manually (by moving the map and zooming) or use the search option from the top menu. The search option allows you to find any location in the world just by typing its name into the input filed, after that, found location will by directly displayed in the center of the map.ġ. No GPS position acquisition is required, all markers can be added manually. The viewfinder in the middle of the map should help you determine where exactly you are placing the makers. After that the distance or area calculation is done automatically and the result is displayed in the left top corner. All you need to do is just add a bunch of points on a map using the red marker button from the top application menu.
STREETVIEW RULER TOOL FREE
Free Maps Ruler allows you to easily measure the distance and the area between selected points on a map.
These findings indicate that Google Earth high-resolution imagery has a horizontal positional accuracy that is sufficient for assessing moderate-resolution remote sensing products across most of the world's peri-urban areas.Free Maps Ruler allows you to easily measure the distance and the area between selected points on a map. The accuracy of control points in more-developed countries is 24.1 meters RMSE, which is significantly more accurate than the control points in developing countries (44.4 meters RMSE t-test p-value < 0.01). The control points derived from satellite imagery have an accuracy of 22.8 meters RMSE, which is significantly more accurate than the 48 control-points based on aerial photography (41.3 meters RMSE t-test p-value < 0.01). Relative to Landsat GeoCover, 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). Landsat GeoCover is an orthorectified product with known absolute positional accuracy of less than 50 meters root-mean-squared error (RMSE). Then the correct translation should be : 'Rgle pour Google Maps gratuite' or 'Rgle gratuite pour Google Maps'.
In this case, 'Ruler' have to be translated as 'Rgle'. Google Earth with Landsat GeoCover scenes over a global sample of 436 control points located in 109 cities worldwide. This French translation sounds very stupid : 'Cartes Gratuit Souverain'. In: Simpósio Brasileiro de Sensoriamento Remoto, 10,Ĭuritiba, PR, 2011. Validação de imagens de alta resolução do Google Earth para produçãoĭe mapas. I suppose that in the US the results may be even better. Of course this is just a case of study, and these results depend on your area of study. *the error is just 1,39% for perimeters calculation īased on these results they concluded that you can use Google Earth as a good source for mapping in scales smaller than 1:150000, assuming the planimetrical error as 0,1 mm.
STREETVIEW RULER TOOL PRO
Google Earth Pro allows the user to measure distance across a surface area, a path. *the error is just 3,54% for polygon measurements out, and change aspect, tilting to view the horizon and Street View.
STREETVIEW RULER TOOL HOW TO
*the error is just 0,44% for line measurements How to measure, for instance, the distance between a wind turbine and the nearest resident.
In 2011 two brazilians published an article about it, and they concluded that:
