Sažetak
The paper is a condensed presentation of the experimental part of my graduation project
(Bitenc, 2006), which I carried out at the Institute for Photogrammetry and Remote sensing (I.P.F.) at the Vienna University of Technology during my Erasmus exchange program. The main topic is attractive, useful and advanced technology - airborne laser scanning, which was used in the Neusiedler See project in order to enable hydrological analyses. The aim of this project, which was part of the international SISTEMaPARC project in the framework of the transnational European project INTERREG IIIB CADSES, was refilling drained natural basins with water, so centimeter accuracy of digital terrain model (DTM) was required. Its high relative and absolute accuracy was obtained by using an appropriate post-processing method. The paper presents analysis of the DTM quality, which was accessed with local quality parameters. According to the results, the DTM of the Neusiedler See National Park reaches 4 cm accuracy in height. The second analysis, described in this paper, aims to investigate intensity values measured with laser scanner. Intensity is a side product of ALS, but could be very useful for recognizing the scanned objects, while it gives some semantic information directly to the 3D data. The possibility to use it for land cover identification and classification was investigated. Some land cover is separable with intensity data, but it was discovered that ALS data are not sufficient.
