Abstract
LiDAR (Light Detecton And Ranging) data are very useful in geographical, historical and archeological studies. It is caused by large precision and concentration of this type of data, which makes it possible to study small forms in relief, like unmetalled roads, historical agricultural systems, or trench lines. The advantage of LiDAR is independence from changes in land cover (afforestation, development). The aim of this article is test on the usability of LiDAR data in research of trench lines built during Second World War in Poland, in Beskidy Mountains. The study area selected to this text was located in Jałowiec Range and Mędralowa Mountain Group in south-west of Małopolskie Province, south of Poland. Jałowiec Range and Mędralowa Mountain Group is a continuation to the north of the Babia Góra Massif (Beskid Żywiecki, Carpathians). The fortifications were been built in this area before and during the Second World War. The first objects were built by the Polish Army in 1939 and second time there were built two large fortification lines in 1944, by Polish people forced to do it by German soldiers. Most objects in the studied area were made on the slopes of Malikowski Groń. The objects constructed in 1944 have been preserved in good condition up to the present day. Few objects have been transformed by the geomorphological processes and by overgrown trees and shrubs on them. These objects have survived to this day, because they were not damaged during hostilities. The trench lines and objects are visible quite well in LiDAR data, which allows you to reconstruct their line even in forest areas.
