For the reason that biodiversity loss is one of the major ecological problems in the EU, it is necessary to establish efficient workflows for the registration and monitoring of woody vegetation landscape features. In the paper, we propose and evaluate a methodology for automated detection of changes in woody vegetation landscape features from a digital orthophoto (DOP). We demonstrate its ability to capture most of the actual changes in the field and thereby provide valuable support for more efficient maintenance of landscape feature layers, which is important for the shaping of future environmental policies. While the most reliable source for vegetation cover mapping is a combination of LiDAR and high-resolution imagery, it can be prohibitively expensive for continuous updates. The DOP from cyclic aerial photography presents an alternative source of up-to-date information for tracking woody vegetation landscape features in-between LiDAR recordings. The proposed methodology uses a segmentation neural network, which is trained with the latest DOP against the last known ground truth as the target. The output is a layer of detected changes, which are validated by the user before being used to update the woody vegetation landscape feature layer. The methodology was tested using the data of a typical traditional Central European cultural landscape, Gori\u010dko, in north-eastern Slovenia. The achieved F1 of per-pixel segmentation was 83.5% and 77.1% for two- and five-year differences between the LiDAR-based reference and the DOP, respectively. The validation of the proposed changes at a minimum area threshold of 100 m2 and a minimum area percentage threshold of 20% showed that the model achieved recall close to 90%.<\/jats:p>","DOI":"10.3390\/rs15112766","type":"journal-article","created":{"date-parts":[[2023,5,27]],"date-time":"2023-05-27T16:17:33Z","timestamp":1685204253000},"page":"2766","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Detection and Monitoring of Woody Vegetation Landscape Features Using Periodic Aerial Photography"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4468-0290","authenticated-orcid":false,"given":"Damjan","family":"Strnad","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, 2000 Maribor, Slovenia"}]},{"given":"\u0160tefan","family":"Horvat","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, 2000 Maribor, Slovenia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2160-0529","authenticated-orcid":false,"given":"Domen","family":"Mongus","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, 2000 Maribor, Slovenia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4419-5295","authenticated-orcid":false,"given":"Danijel","family":"Ivajn\u0161i\u010d","sequence":"additional","affiliation":[{"name":"Faculty of Natural Sciences and Mathematics, University of Maribor, 2000 Maribor, Slovenia"},{"name":"Faculty of Arts, University of Maribor, 2000 Maribor, Slovenia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6210-0889","authenticated-orcid":false,"given":"\u0160tefan","family":"Kohek","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, 2000 Maribor, Slovenia"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,26]]},"reference":[{"key":"ref_1","unstructured":"Kokalj, Z., Stan\u010di\u010d, L., Noumonvi, K.D., and Andrej, K.
