vtkGeoGraticule

Section: Visualization Toolkit Geo Vis Classes

Usage

This filter generates polydata to illustrate the distortions introduced by a map projection. The level parameter specifies the number of lines to be drawn. Poles are treated differently than other regions; hence the use of a Level parameter instead of a NumberOfLines parameter. The latitude and longitude are specified as half-open intervals with units of degrees. By default the latitude bounds are [-90,90[ and the longitude bounds are [0,180[.

To create an instance of class vtkGeoGraticule, simply invoke its constructor as follows
