I checked the link and now I figured the DEM. Very interesting link! LOL, I had been so hurry and excited in developing, that I didn't remember to checkthe link you posted earlier, or maybe my eyes are coming blind. I'm sorry about that. But that one you just posted will be in closer examination in very near future. First I have to try to develop the code more flexible and automatical. Yet it works only with fixed values.

Maybe I shoul split project process to 2 different ones. Reading coordinate data is this one as originally and converting to displacement data would be another. There is still many things to develop with the main parts alone...

Cheers!
