It is a polygon method. Nearest composite value to be estimated to the point with this method is assigned as the estimation value.
If the average values of blocks will be estimated, number of block divisions should be entered for x, y and z directions. Block division number should be 1 for x, y and z directions in point estimation.
Division numbers of block estimations are dependent on the anisotropy direction and degree of the variable to be estimated. These numbers can be taken as equal to three in isotropy.
If you want to keep the estimation results, you must determine the file and index of the file by clicking three dot (...) button under "Estimation Result File". The file is saved in *.sgems extension.
After entering the parameters, estimation is done by clicking "OK" and blocks will be thematized.
