20.500.12556/RUL-114452 Extraction of visible boundaries for cadastral mapping based on UAV imagery In order to transcend the challenge of accelerating the establishment of cadastres and to efficiently maintain them once established, innovative, and automated cadastral mapping techniques are needed. The focus of the research is on the use of high-resolution optical sensors on unmanned aerial vehicle (UAV) platforms. More specifically, this study investigates the potential of UAV-based cadastral mapping, where the ENVI feature extraction (FX) module has been used for data processing. The paper describes the workflow, which encompasses image pre-processing, automatic extraction of visible boundaries on the UAV imagery, and data post-processing. It shows that this approach should be applied when the UAV orthoimage is resampled to a larger ground sample distance (GSD). In addition, the findings show that it is important to filter the extracted boundary maps to improve the results. The results of the accuracy assessment showed that almost 80% of the extracted visible boundaries were correct. Based on the automatic extraction method, the proposed workflow has the potential to accelerate and facilitate the creation of cadastral maps, especially for developing countries. In developed countries, the extracted visible boundaries might be used for the revision of existing cadastral maps. However, in both cases, the extracted visible boundaries must be validated by landowners and other beneficiaries. cadastre land parcel land plot land cadastre cadastral boundaries cadastral maps UAV image processing image segmentation feature extraction object extraction kataster zemljiška parcela katastrska meja UAV obdelava podob ekstrakcija objektov true false true Angleški jezik Slovenski jezik Članek v reviji 2020-02-28 14:34:25 2020-02-28 14:37:46 2022-08-26 03:50:39 0000-00-00 00:00:00 2019 0 0 20 str. iss. 13, art. 1510 Vol. 11 8 maj 2019 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 528.44 2072-4292 10.3390/rs11131510 8835681 32345133 remotesensing-11-01510-v2_(1).pdf remotesensing-11-01510-v2_(1).pdf 1 9827848DE9006DB491BFD400D9497071 f2c27887589ffab38d9d28e7155e1ccd1d6de36e8343844276b5e32bbc61fbad 38f9c719-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=126650 https://www.mdpi.com/2072-4292/11/13/1510 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=126651 Fakulteta za gradbeništvo in geodezijo 0 0 0
