I should note that there are many methods of regularization of the
irregular points. Moreover, those methods are closely related to the
nature of your data and to the results you are are want to get. So it is
not so trivial task. If we want to prepare the regularzation module we
should implement a bunch of the different methods, at least kriging,
tringulation, inverse distance --- those are come to mind in first of all.
