Aerial laser scanning (lidar) enables quick acquisition of terrain data and it can be used for the study of terrain under the vegetation. Therefore lidar is very appropriate for different geomorphologic studies. In this paper different characteristics of lidar are described, especially those which are important for decision, if lidar data are appropriate for our needs. The most important factors are the number of points per area unit (points/m2) and the positional accuracy of the lidar data. On the example of landslides, rockfalls and different karst features the most suitable lidar data sets was defined.

The paper presents an overview of different geodetic measurements of Triglav glacier from 1952 to 2011. In 1952 the first geodetic tahimetric measurements were conducted. The second one followed in 1995. In the 1999 the first photogrammetric and geodetic measurements started which were conduced once per two years until 2007. With 2007 the photogrammetric and geometric measurements are conducted on yearly basis. Geodetic and photogrammetric measurements of Triglav glacier are used in this project as a control measurements.
