Michaliči,
ten posun môže byť aj kvôli nerovnakým súradnicovým systémom. Tie 
lidarové dáta sú v UTM34N.

ahojte,
tak asi som bol na limite therionu pretoze ked som konvertoval na
rozmer 2 x2 m povrch mi spravilo z  lidar dat. akurat ze dve hrany mam
ohranicene na 0 a vyskovo sa mi to zda byt nepresne. respektive
posunute o nejake metre..

v prilohe teda prvy polo/uspesny pokus povrchu z lidar dat .. .

Ahojte,
hram sa s lidar datami a mam trosku problem. neviem ci som sa dostal
na obmedzenie therionu alebo robim nieco zle.

vstupne data som mal stvorec

netusim ci mam spravny grid, tak ak sa dakto do toho vyzna prosim
skontrolujte pretoze pri kompilacii dostanem chybu..
