Constructor Detail

DemToTinThread

public DemToTinThread(GUIFrame gf,
                      int numVertices,
                      float tolRMSE,
                      float tolError,
                      boolean createErrorSurf)

Converts a DEM into TIN representation. TIN detail can be determined by any combination of numSamples, tolRMSE or tolError, where error is difference between TIN and DEM height at any point.

Parameters:

gf - GUI frame containing DEM (and TIN).

numVertices - Maximum number of vertices.

tolRMSE - Maximum Root Mean Squared Error tolerated.

createErrorSurf - Generates an error surface if true.
