TIN-model

TIN-model represents a many-sided surface - an irregular network of triangles, vertices  of  which are initial control points, and also points of the metrics of structural lines and the areas of filling.

TIN-model is created according to a source vector map within the limits of the range of a triangulation including point,  line and polygon  objects, with the characteristic "absolute height" or with the three-dimensional metrics. For creation of TIN-model it is required not less than four point objects.
