In general, damaged-building detection with SAR data has been conducted based on change detection using temporal SAR data acquired in the same observation mode. However, it is not always possible to use SAR data obtained with the appropriate observation mode in unexpected events such as natural disasters. This study aims to detect earthquake-induced damaged buildings using temporal SAR data having different observation modes. We presented a contextual change analysis method to map damaged buildings based on novel textural features. This study was conducted using the bi-temporal Komapsat-5 data obtained in different polarization modes. Experimental results for the area severely damaged by the 2016 Kumamoto earthquake showed that the proposed textural analysis can improve detectability in building-damaged areas while maintaining low false alarm rates in agricultural areas. According to the grid-based accuracy analysis, the proposed method can successfully detect the damaged areas with a detection rate of about 72.5% and false alarms of about 6.8% even on challenging data sets.<\/jats:p>","DOI":"10.3390\/rs15020308","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T02:00:57Z","timestamp":1672884057000},"page":"308","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Detection of Damaged Buildings Using Temporal SAR Data with Different Observation Modes"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3733-8227","authenticated-orcid":false,"given":"Minhwa","family":"Kim","sequence":"first","affiliation":[{"name":"Energy and Mineral Resources Engineering, Sejong University, 209, Neungdong-ro, Gwangjin-gu, Seoul 05006, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0887-1348","authenticated-orcid":false,"given":"Sang-Eun","family":"Park","sequence":"additional","affiliation":[{"name":"Energy and Mineral Resources Engineering, Sejong University, 209, Neungdong-ro, Gwangjin-gu, Seoul 05006, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4527-1619","authenticated-orcid":false,"given":"Seung-Jae","family":"Lee","sequence":"additional","affiliation":[{"name":"Satellite Application Division, Korea Aerospace Research Institute, 169-84, Gwahak-ro, Yuseong-gu, Daejeon 34133, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Coburn, A., and Spence, R.
