However, current methods using traditional surveys cannot meet the demand for the rapid development of urban land management. There is an urgent need to develop new methods to overcome the shortcomings of conventional methods. To address the issue, this study used the random forest (RF), support vector machine (SVM), and artificial neural network (ANN) models to build machine-leaning methods for urban land-use classification. Taking Hangzhou as an example, these machine-leaning methods could all successfully classify the essential urban land use into 6 Level I classes and 13 Level II classes based on the semantic features extracted from Sentinel-2A images, multi-source features of types of points of interest (POIs), land surface temperature, night lights, and building height. The validation accuracy of the RF model for the Level I and Level II land use was 79.88% and 71.89%, respectively, performing better compared to SVM (78.40% and 68.64%) and ANN models (71.30% and 63.02%). However, the variations of the user accuracy among the methods depended on the urban land-use level. For the Level I land-use classification, the user accuracy was high, except for the transportation land by all methods. In general, the RF and SVM models performed better than the ANN model. For the Level II land-use classification, the user accuracy of different models was quite distinct. With the RF model, the user accuracy of educational and medical land was above 80%. Moreover, with the SVM model, the user accuracy of the business office and educational land classification was above 75%. However, the user accuracy of the ANN model on the Level II land-use classification was poor. Our results showed that the RF model performs best, followed by SVM model, and ANN model was relatively poor in the essential urban land-use classification. The results proved that the use of machine-learning methods can quickly extract land-use types with high accuracy, and provided a better method choice for urban land-use information acquisition.<\/jats:p>","DOI":"10.3390\/rs12172817","type":"journal-article","created":{"date-parts":[[2020,8,31]],"date-time":"2020-08-31T08:11:19Z","timestamp":1598861479000},"page":"2817","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Comparison of Machine-Learning Methods for Urban Land-Use Mapping in Hangzhou City, China"],"prefix":"10.3390","volume":"12","author":[{"given":"Wanliu","family":"Mao","sequence":"first","affiliation":[{"name":"Department of Land Management, Zhejiang University, Hangzhou 310058, China"},{"name":"Zhejiang Academy of Surveying and Mapping, Zhejiang 311100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Debin","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Land Management, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Hou","sequence":"additional","affiliation":[{"name":"Department of Land Management, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xue","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Land Management, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7533-3294","authenticated-orcid":false,"given":"Wenze","family":"Yue","sequence":"additional","affiliation":[{"name":"Department of Land Management, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,31]]},"reference":[{"key":"ref_1","first-page":"59","article-title":"Comparison of Machine Learning Methods for Land Use\/Land Cover Classification in the Complicated Terrain Regions","volume":"34","author":"Gu","year":"2019","journal-title":"Remote Sens.
