Airborne laser scanning of Slovenia will for the first time allow the analysis of Slovenia's surface at high resolution, with height accuracy of LiDAR generated DTM 1 m × 1 m below 15 cm (RMSE) and postural error below 30 cm (RMSE). This is a significant improvement in comparison to the previously existing photogrammetric DTM 5 m × 5 m, with height accuracy of 1 m (RMSE) in the open field and 3 m (RMSE) in overgrown field. The article presents products of laser scanning of Slovenia as well as the quality control of products. Latter shall be obtained on the basis of laser scans with a density of 5 points / m2 or for critical areas and of 2 points / m2 for forested areas. The derived products include classified point-clouds, the terrain, DMR 1 m × 1 m, and the image of analytical shading of DMR at 1m resolution. In the paper, we also describe the possibilities and potentials of these products to study the surface and built-up areas in Slovenia.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 18646806The achievements of the project have got an important impact also in the broad publicity. Namely, our algorithm for buildings recognition has been evaluated as the best algorithm in its category at the competition organised by the International Society for Photogrammetry and Remote Sensing. This success has gained a large attraction in Slovene media. We would like to stress very popular weekly public voting on the most popular Slovene radio station VAL 202, where our researcher Domen Mongus was convincingly elected for the personality of the week.
F.18 Transfer of new know-how to direct users (seminars, fora, conferences)
COBISS.SI-ID: 18425622gLiDAR software tool has been designed for object recognition in the LiDAR data, and supports creation of digital terrain models (DTM) and the classification of captured points into terrain, buildings and vegetation classes. In this way, gLiDAR achieves the essential steps in the preparation of content for geographic information systems and geospatial analysis of large geographical areas with extremely high accuracy. gLiDAR has been used for processing of the LiDAR data for the whole Republic of Slovenia.
