Area Calculation Tool
Global Mapper makes it really easy to calculate and measure an area. All you have to do is select the measure tool from the toolbar:
Once the tool is selected
- Left click on the point to begin the measurement. Move the mouse, which will draw a line, to the point where the measurement should stop.
- Repeat step 1 until you have defined the entire path or area that you wish to measure.
- Right click the right mouse button and select “Stop Measuring” from the list using a left click. Notice that “Stop Measuring” and “Close polygon” choices are now grayed out. The measurement(s) will be displayed on the left side of the status bar below.
- In order to change measurements right click and choose a new unit using a left click. You may continue to change the measurement display by selecting different units. The distance will be displayed in kilometers, meters, miles or feet for a line, and in square feet, square meters, square miles, acres, or hectares for areas.
