| dc.description.abstract | This study aims to compare two sets of LiDAR, one being Single Photon LiDAR and the
other one being the regular LiDAR with 2 meters resolution. The two LiDAR datasets cover
an area over Klyftamon, a nature reserve located in Skara, Västra Götaland, known for its
geological history with the Baltic Ice Lake. Two areas were selected in Klyftamon that were
abundant in boulders, with the aim is to test which of the two sets of LiDAR data can detect
the boulders. Aside from the main purpose, it is interesting to see if the relatively new
technology of Single Photon LiDAR can be used in the field of geomorphology.
What can be noted from this study is that it is possible to detect boulders, adjustment from
hillshade maps to slope maps had to be made for the detection of boulders. However, given
the fine pixel resolution of 0.2 meters, not a lot of boulders were detected with the SPL. What
was shown in the study was that Single Photon LiDAR worked better for analysis in bouldery
areas that lacked vegetation, some boulders could be identified, but not all. In the treecovered
area, no boulders could be seen. However, the use of drone photos turned out to be
useful. The drone data gave a high-resolution image, where the boulders that were measured
could be identified more easily than it could with the SPL data alone. | en |
