This tool is used to detect your current position on the map.
Click on the Location() tool. A red dot and a circle will be drawn on the map displaying you approximate location.
The circle represents radius in which you may be located.
You can also snap to this point when using Measure distance(), Measure area() or Editing() tool.
Upon activate the tool will try to zoom into the new acquired location until the precision is higher than 100 meters.
To deactivate the location mark click on the tool again.
