Improving the accuracy of mapping a disaster area at different time is an essential step to analyze the relationship between human activity and environment. The goals of this study were to test the performance of different processing procedures and examine the effect of adding normalized difference vegetation index (NDVI) as an additional classification feature for mapping land cover changes due to a disaster. Using Landsat ETM+ and OLI images of the Bento Rodrigues mine tailing disaster area, we created two datasets, one with six bands, and the other one with six bands plus the NDVI. We used support vector machine (SVM) and decision tree (DT) algorithms to build classifier models and validated models performance using 10-fold cross-validation, resulting in accuracies higher than 90%. The processed results indicated that the accuracy could reach or exceed 80%, and the support vector machine had a better performance than the decision tree. We also calculated each land cover type\u2019s sensitivity (true positive rate) and found that Agriculture, Forest and Mine sites had higher values but Bareland and Water had lower values. Then, we visualized land cover maps in 2000 and 2017 and found out the Mine sites areas have been expanded about twice of the size, but Forest decreased 12.43%. Our findings showed that it is feasible to create a training data pool and use machine learning algorithms to classify a different year\u2019s Landsat products and NDVI can improve the vegetation covered land classification. Furthermore, this approach can provide a venue to analyze land pattern change in a disaster area over time.<\/jats:p>","DOI":"10.3390\/rs11212548","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T05:18:26Z","timestamp":1572499106000},"page":"2548","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Spatial\u2013Temporal Analysis of Land Cover Change at the Bento Rodrigues Dam Disaster Area Using Machine Learning Techniques"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2764-5031","authenticated-orcid":false,"given":"Dong","family":"Luo","sequence":"first","affiliation":[{"name":"Department of Geography and Geospatial Sciences, Kansas State University, Manhattan, KS 66506, USA"}]},{"given":"Douglas G.","family":"Goodin","sequence":"additional","affiliation":[{"name":"Department of Geography and Geospatial Sciences, Kansas State University, Manhattan, KS 66506, USA"}]},{"given":"Marcellus M.","family":"Caldas","sequence":"additional","affiliation":[{"name":"Department of Geography and Geospatial Sciences, Kansas State University, Manhattan, KS 66506, USA"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1016\/j.landusepol.2017.10.026","article-title":"Changes in land use and land cover as a result of the failure of a mining tailings dam in Mariana, MG, Brazil","volume":"70","author":"Aires","year":"2018","journal-title":"Land Use Policy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"425","DOI":"10.1007\/s10346-013-0391-7","article-title":"Landslide susceptibility mapping using GIS-based multi-criteria decision analysis, support vector machines, and logistic regression","volume":"11","author":"Kavzoglu","year":"2014","journal-title":"Landslides"},{"key":"ref_3","first-page":"1","article-title":"Landslide susceptibility mapping based on GIS and support vector machine models for the Qianyang County, China","volume":"75","author":"Chen","year":"2016","journal-title":"Environ.
