Zastosowanie fotogrametrii niskopułapowej w badaniach przestrzennego zróżnicowania pokrywy glebowej przekształconej w wyniku denudacji antropogeniczne

Low-altitude photogrammetry in studies of soil cover variability of areas transformed by anthropogenic denudation

Summary: Anthropogenic denudation leads to strong transformations of the soil cover of agricultural areas of the moraine plateaus of northern Poland. As a result, a wide range of different types of soils is formed - truncated in the upper parts of the slopes and accumulative - at the foot of them and in the depressions, too. Presented studies show a new attempt to use unmanned aerial vehicles (UAV) low-altitude photogrammetry in determining the extent and degree of erosional alterations of soil cover. An agriculturally used undulating moraine plateau of the Dobrzyń Lake District was chosen for research. After the UAV survey an orthophotomosaic and a digital terrain model (DEM) using Agisoft Photoscan 1.4.5 software were made. Photogrammetric analyses allowed the selection of six sites for soil profiles investigations. The obtained results confirm the need to use in the research of denudation transformations algorithms that take into account the parameters of the terrain in connection with the analysis of spatial variability of colour variations of surface soil horizons. UAV photogrammetry is therefore a comprehensive tool giving great opportunities to develop this type of research.
