area.tcl

This example shows how to build surface by approximating areas with constant real numbers. In this example 5 different areas were used. Suppose that for three of them (area1, area3 and area5) exact values are known, for other two (area2 and area4) - only approximative values. So, we want to build surface, which approximates as exactly as possible values for areas 1,3 and 5, and "not so exactly" for areas 2 and 4.

To produce this surface we should do the following things:

• load areas to the memory
• create equidistant grid
• set some additional parameters (Description of the surfit gridding algorithm tol "tolerance", map_name)
• create sequence of gridding rules (how to use areas and space between them)
• run Description of the surfit gridding algorithm algorithm
• save results to file

Here is the image of the resulting surface (green colour for areas 1,3 and 5, red colour for areas 2 and 4):
