DTM Control.

This tool allows you to control the coherence of the DTM by detecting superposed or intersecting triangles, and/or detect 3D Faces having a 2D Surface inferior to a given value, or a maximal slope greater than a value.

Triangles to Control

• Detect the superposed or intersecting triangles : Check this option to detect superposed triangles (that is, those of which the 3 points are identical in XY, while in Z they can be variable), or intersecting triangles.
• Detect the triangles of which the 2D surface is smaller than : Check this option to detect triangles with a 2D surface that is smaller than the input value.
• Detect the triangles of which the max slope is greater than : Check this option to detect triangles with a maximal slope that is grater than the input value.
  

Move the erroneous triangles to Layer

• Layer : Enter the name of the layer in which the triangles corresponding to criteria are displaced, or click on to choose from a list.

Adjust the parameters in the dialog box, then click on "OK". FlashMNT then displays the following command line:

>> Select the 3D Faces :

Select the 3D Faces, then validate.

Notes : None.
