If you need a tool that can help you calculate land area or distance between two locations, then you are in the right place. This app is a great map-based distance calculator tool. It is GPS to select a start point, but you may also manually set this by selecting the area on the map. 

It calculates the distances between two points on the map. Simply select the points and click on the calculate button. The program will then calculate the distances and areas for you. You can also select the type of map you want to use, either normal, satellite, terrain, or hybrid.

It is very easy to use and is very accurate. If you want to save the calculated areas or distances, you can do so. The saved areas will be displayed in a list, and you can easily view them or use them for other purposes.
