Abstract
Slovenia has a crucial problem of regular updating of topographic data at different levels. The largest scale map which is regularly updated is Nationaltopographic map at the scale 1: 50,000, but without any detailed data capture in wooden areas. Larger scale topographic maps and basic topographic database were captured only partly and they have no strict updating program. On the other hand the airborne laser scanning data became one of the most promising source data for deriving different spatial data. Some methods and procedures are already efficiently used in urban environment and forestry, while use for deriving topographic features is still rare. Therefore some tests about possible use of ASL data for updating topographic data were made. As a study area part of Sava valley near the Jesenice with neighboring slopes was used. According to analyses and tests some rules which can be followed in attempt to partly automate the procedure of recognising specific features for updating topographic maps were extracted.
