Creating Grids Using
Interpolation
This section describes the basic commands associated with the creation of
numeric grid files using interpolation techniques. The Vertical Mapper
Interpolation Wizard supports six interpolation techniques:
• Triangulation with Smoothing (TIN)
• Inverse Distance Weighting (IDW)
• Natural Neighbour (simple and advanced)
• Rectangular
• Kriging
