Abstract
The software combines the simplification potential and the splines with the generalized axial symmetry. It significantly improves all geometric and shape parameters of contour lines, namely in flatter areas.
The simplified contour lines preserve the given vertical error, lie within the vertical buffer, are parallel, aesthetically pleasing, and have similar spacing; their artificial oscillations are significantly reduced. Unlike complex generalization methods, the proposed solution does not interfere with the DTM but performs only a correction of the cartographic representation of contour lines.
