Building by a  vector map

To build  the matrix of layers it is required the set of point objects having three coordinates  (X, Y, H) or two coordinates and the Absolute height characteristic, and also set of the semantic characteristics. Semantics of objects should contain values of the layers powers in the assign point. The conformity of semantic codes  and title of matrix layers is indicated  in the matrix legend file.

It is necessary to add an appropriate height matrix to the open vector map for usage the information about a relief from a matrix of heights at building.

The matrix of  layers may be constructed on all region, or on a preset district segment in the region.

It is necessary to switch on All region mode in Parameters group for construction the matrix on all region.

It is necessary press Select button in Parameters group and choose a district segment on a map by two left mouse button clicks for construction the matrix on the preset district segment. To press Change button and to execute the changes by mouse for changing the borders of output area. The double-clicking of the left mouse button is the termination of a change mode.

The segment borders may be preset also by coordinates in South, North, West, East windows  in meters after pressing Coordinate button.

The information on a relief undertakes from the appropriate map objects, if there are opened matrixes of heights  in the matrix of layers creation region the information on a relief will undertake from a matrix of heights at matrix construction.
