UAS PHOTOGRAMMETRY AND OBJECT-BASED IMAGE ANALYSIS (GEOBIA): EROSION MONITORING AT THE KAZÁR BADLAND, HUNGARY
A remarkable badland valley is situated near Kazár, NE-Hungary, where rhyolite tuff outcrops as greyish white cliffs and white barren patches. The landform is shaped by gully and rill erosion processes. We performed a preliminary state UAS survey and created a digital surface model and ortophotogr...

| description | A remarkable badland valley is situated near Kazár, NE-Hungary, where rhyolite tuff outcrops as greyish
white cliffs and white barren patches. The landform is shaped by gully and rill erosion processes. We
performed a preliminary state UAS survey and created a digital surface model and ortophotograph. The
flight was operated with manual control in order to perform a more optimal coverage of the aerial images.
The overhanging forests induced overexposed photographs due to the higher contrast with the bare
tuff surface. The multiresolution segmentation method allowed us to classify the ortophotograph and
separate the tuff surface and the vegetation. The applied methods and final datasets in combination with
the subsequent surveys will be used for detecting the recent erosional processes of the Kazár badland. |
