At frst (4.1), a brief introduction is given about basic operational elements and accessories of UAS. Then, recent camera/sensor technologies allowing various survey solutions are going to be discussed. Once these hardware components are presented, the detailed workflow of a basic UAV-based mapping procedure is described (4.2). A further discussion focuses not only on the analytical or planning phases but also on providing useful information on the operational and processing parts as well (4.3). Then, there comes image acquisition and project planning (4.4). The photogrammetry-based image processing requires detailed expertise and attention; Sect. 4.5 maybe helpful to avoid potential mistakes. The last section (4.6) summarizes some aspects of the use of LiDAR technologies in UAV-based surveys.}, year = {2018}, pages = {91-126}, orcid-numbers = {Bertalan, László/0000-0002-5963-2710; Lénárt, Csaba/0000-0002-1483-8723} } @article{MTMT:30331410, title = {Természeti és antropogén tényezők szerepe az Alsó-Tisza menti partfal-instabilitások kialakulásában = Natural and Anthropogenic Factors Generating Riverbank Instabilities along the Lower Tisza River}, url = {https://m2.mtmt.hu/api/publication/30331410}, author = {Kis, Éva and Lóczy, Dénes}, doi = {10.32643/fk.142.4.5}, journal-iso = {FÖLDRAJZI KÖZLEMÉNYEK}, journal = {FÖLDRAJZI KÖZLEMÉNYEK}, volume = {142}, unique-id = {30331410}, issn = {0015-5411}, year = {2018}, pages = {328-343}, orcid-numbers = {Lóczy, Dénes/0000-0002-2542-6775} } @article{MTMT:30315457, title = {Issues of Meander Development: Land Degradation or Ecological Value?

Nowadays, land managers, stakeholders, and scientists are discussing how this process affects the surrounding landscapes. Usually, due to a land mismanagement of agroforestry activities or urbanization plans, river regulations are designed to reduce anthropogenic impacts such as bank erosion, but many of these regulations resulted in a degradation of habitat diversity. Regardless, there is a lack of information about the possible positive effects of meandering from the ecological point of view. Therefore, the main aim of this study was to investigate a 2.12 km long meandering sub-reach of Sajo River, Hungary, in order to evaluate whether the process of meander development can be evaluated as a land degradation processes or whether it can enhance ecological conservation and sustainability. To achieve this goal, an archive of aerial imagery and UAV (Unmanned Aerial Vehicle)-surveys was used to provide a consistent database for a landscape metrics-based analysis to reveal changes in landscape ecological dynamics. Moreover, an ornithological survey was also carried out to assess the composition and diversity of the avifauna. The forest cover was developed in a remarkable pattern, finding a linear relationship between its rate and channel sinuosity. An increase in forest areas did not enhance the rate of landscape diversity since only its distribution became more compact. Eroding riverbanks provided important nesting sites for colonies of protected and regionally declining migratory bird species such as the sand martin. We revealed that almost 70 years were enough to gain a new habitat system along the river as the linear channel formed to a meandering and more natural state.}, keywords = {DIVERSITY; BANK EROSION; LANDSCAPE METRICS; UAV; Sajo River}, year = {2018}, eissn = {2073-4441}, orcid-numbers = {Bertalan, László/0000-0002-5963-2710; Novák, Tibor József/0000-0002-5514-9035; Szabó, Szilárd/0000-0002-2670-7384} } @article{MTMT:3391744, title = {Water Related Disaster Management Supported by Drone Applications}, url = {https://m2.mtmt.hu/api/publication/3391744}, author = {Restás, Ágoston}, doi = {10.4236/wjet.2018.62B010}, journal-iso = {WORLD J ENG TECH}, journal = {WORLD JOURNAL OF ENGINEERING AND TECHNOLOGY}, volume = {6}, unique-id = {3391744}, issn = {2331-4222}, year = {2018}, eissn = {2331-4249}, pages = {116-126}, orcid-numbers = {Restás, Ágoston/0000-0003-4886-0117} } @inproceedings{MTMT:30434827, title = {A creek's hydrological model's generates in HEC-RAS}, url = {https://m2.mtmt.hu/api/publication/30434827}, author = {Nagy, Bálint}, booktitle = {Student V4 Geoscience Conference and Scientific Meeting GISÁČEK}, unique-id = {30434827}, year = {2017}, pages = {81-87} } @inproceedings{MTMT:30434796, title = {Az árvízi védekezés támogatása hidrológiai modellezéssel egy kisvízfolyás példáján}, url = {https://m2.mtmt.hu/api/publication/30434796}, author = {Nagy, Bálint}, booktitle = {Az elmélet és a gyakorlat találkozása a térinformatikában VIII. = Theory meets practice in GIS}, unique-id = {30434796}, year = {2017}, pages = {245-252} } @inproceedings{MTMT:3073698, title = {Ártéri domborzatfelmérés és elöntésszimuláció: gyorsan, hatékonyan és pontosan – a helyi árvízi védekezés érdekében}, url = {https://m2.mtmt.hu/api/publication/3073698}, author = {Kohán, Balázs and Deák, Márton and Mészáros, János and Nagy, Balázs and Szabó, Judit Alexandra and Szalai, Zoltán}, booktitle = {Az elmélet és a gyakorlat találkozása a térinformatikában VII. = Theory meets practice in GIS}, unique-id = {3073698}, year = {2016}, pages = {229-235}, orcid-numbers = {Kohán, Balázs/0000-0001-5111-0224; Mészáros, János/0000-0003-2604-3052; Szalai, Zoltán/0000-0001-5267-411X} } @article{MTMT:3125037, title = {UAS photogrammetry and object-based image analysis (GEOBIA): erosion monitoring at the Kazár badland, Hungary}, url = {https://m2.mtmt.hu/api/publication/3125037}, author = {Bertalan, László and Túri, Zoltán and Szabó, Gergely}, doi = {10.21120/LE/10/3-4/10}, journal-iso = {ACTA GEOGR DEBRECINA LANDSCAPE}, journal = {ACTA GEOGRAPHICA DEBRECINA LANDSCAPE AND ENVIRONMENT SERIES}, volume = {10}, unique-id = {3125037}, issn = {1789-4921}, abstract = {A remarkable badland valley is situated near Kazár, NE- Hungary, where rhyolite tuff outcrops as greyish white cliffs and white barren patches.

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.
