Compare matrixes of heights

Matrixes of heights compare task is intended for comparison of the information of two one-type matrixes of heights.

Source data are two open matrixes of heights. Matrixes of heights should be of one-type. Otherwise comparison is not carried out.

The task is caused onto an execution by a choice of the corresponding menu item in Run Application.

Parameters of a created matrix are set in Matrix compare dialog. Originally parameters are established by a map and by the most exact open matrix.

In dialog it is possible to change scale and resolution (element size) of created matrix.

Except for that for an execution of building it is required to specify a file name and to choose the sizes of created matrix. By default the sizes of a matrix are established on the sizes of the first matrix, and in the further they can be changed by a choice of a corresponding fragment of a map.

The target matrix contains relative heights of the second matrix in relation to the first matrix, that is into each element of a target matrix the difference of heights of the second and first matrix (H2 - H1) is brought. If in any point there is no height even in one of matrixes then the information is not brought into a target matrix.

If it is required into elements of the result matrix to place the module of a difference of heights of the second and first matrix | (H2 - H1) | it is necessary to use the check-box “Calculate height difference by Modulus”.
