| Abstract: | In this essay, Tianjin was used as a study area, the GF-1 WFV was used as the remotely sensed data sources, and the image data, acquired during the critical growing periods of winter wheat in 2016, was combined with the ground survey data, using the technologies of RS, GIS, and etc. The decision tree classification method was used to extract the spatial distribution data of winter wheat in Tianjin City, and the classification accuracy is validated by the confusion matrix method. It can be used as reference for remote sensing survey of crop spatial distribution in other areas. |
