Measurement of lengths and areas (in mm) on a map

After activating the given mode the cursor transforms to a measuring grid with the scale interval of 0.1 mm in an initial map scale.    

The measurements are made by applying of the measuring grid to a measured object.

For measurement of objects having deflection from a vertical or horizontal axis the possibility of measuring grid rotation concerning the left lower corner is stipulated (key S - clockwise, key D - counter-clockwise).
