ic_7845 By the given mode only linear and area objects are processed. The choice of object is possible if the matrix of heights is added to a map or object points have terrain   coordinates  and height.

The object length is defined in view of a relief. Accuracy of calculations depends on a step of interpolation (a step of object division on perimeter on components - pieces). It is established at a choice of a mode unitary, or at a choice of each object - individually. The interpolation step less  the calculations are more exact. At value of an interpolation step equal to zero accuracy  of  calculation  is minimal.

The received object length is deduced in a results window.
