Does anyone have a direct example of a Delphi grid fill using Delaunay triangles or kriging? Any method can fill the grid by "interpolation".
What do I want to do? I have a grid similar to:
22 23 xx 17 19 18 05
21 xx xx xx 17 18 07
22 24 xx xx 18 21 20
30 22 25 xx 22 20 19
28 xx 23 24 22 20 18
22 23 xx 17 23 15 08
21 29 30 22 22 17 09
where xx represent grid cells without data, and the x, y coordinates of each cell are known. Both Kriging triangles and Delaunay triangles can provide “missing” points (which, of course, are fictitious but reasonable meanings).
Kriging is a statistical method for filling in “missing” or inaccessible data in a grid with “reasonable” values. Why do you need this? Fundamentally "delineate" the data. Contour algorithms (e.g. CONREC for Delphi http://local.wasp.uwa.edu.au/~pbourke/papers/conrec/index.html ) can contour regularly distributed data. Search for "kriging" and "Delphi" and you will eventually see the GEOBLOCK project on Source Forge ( http://geoblock.sourceforge.net/) Geoblock has many Delphi pas kriging units based on GSLIB (a Fortran statistical package developed at Stanford). However, all kriging / deline units are dependent on the units referenced in the "Using Delphi" section. Unfortunately, these helper modules are not hosted with the rest of the source code. It seems that none of the kriging blocks can work alone or work without auxiliary blocks that are not located, or in some cases with undefined data types.
