Remote sensing plays an important role in detecting changes in land cover caused by these tropical storms. Remote sensing techniques have been widely used in different phases of disaster risk management because they can deliver information rapidly to the concerned parties. Although remote sensing technology is already available, an examination of appropriate methods based on the type of disaster is still missing. Our goal is to compare the suitability of three different conventional classification methods for fast and easy change detection analysis using high-spatial-resolution and high-temporal-resolution remote sensing imagery to identify areas with windthrow and landslides caused by typhoons. In August 2016, four typhoons hit Hokkaido, the northern island of Japan, creating large areas of windthrow and landslides. We compared the normalized difference vegetation index (NDVI) filtering method, the spectral angle mapper (SAM) method, and the support vector machine (SVM) method to identify windthrow and landslides in two different study areas in southwestern Hokkaido. These methodologies were evaluated using PlanetScope data with a resolution of 3 m\/px and validated with reference data based on Worldview2 data with a very high resolution of 0.46 m\/px. The results showed that all three methods, when applied to high-spatial-resolution imagery, can deliver sufficient results for windthrow and landslide detection. In particular, the SAM method performed better at windthrow detection, and the NDVI filtering method performed better at landslide detection.<\/jats:p>","DOI":"10.3390\/rs12193242","type":"journal-article","created":{"date-parts":[[2020,10,6]],"date-time":"2020-10-06T10:46:17Z","timestamp":1601981177000},"page":"3242","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Comparison of Conventional Change Detection Methodologies Using High-Resolution Imagery to Find Forest Damage Caused by Typhoons"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1749-4858","authenticated-orcid":false,"given":"Flavio","family":"Furukawa","sequence":"first","affiliation":[{"name":"Graduate School of Agriculture, Hokkaido University, Sapporo, Hokkaido 060-8587, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junko","family":"Morimoto","sequence":"additional","affiliation":[{"name":"Graduate School of Agriculture, Hokkaido University, Sapporo, Hokkaido 060-8587, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuhiko","family":"Yoshimura","sequence":"additional","affiliation":[{"name":"Graduate School of Agriculture, Hokkaido University, Sapporo, Hokkaido 060-8587, Japan"},{"name":"Department of Environmental and Symbiotic Science, Rakuno Gakuen University, Ebetsu 069-8501, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masami","family":"Kaneko","sequence":"additional","affiliation":[{"name":"Department of Environmental and Symbiotic Science, Rakuno Gakuen University, Ebetsu 069-8501, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1007\/BF02488116","article-title":"Gap dynamics in climaxFagus crenata forests","volume":"102","author":"Yamamoto","year":"1989","journal-title":"Bot.
