基于多源数据的水稻种植面积提取
Extraction of Paddy Planting Area Based on Multi-source Remote Sensing Data
摘要
Abstract
Introducing analysis method of paddy extraction in critical growth period and variation vectors, with paddy in Haian County of Jiangsu Province as the study subject, taking MODIS data and environment small satellite data as main data source, the law of paddy phenophase period in 2009 was analyzed, and based on these, some appropriate medium resolution data were selected to carry out change vector analysis.The results showed that the method can effectively reflect the change law of paddy pixel, and choosing the time phase based on the analysis of critical phenophase is able to improve the accuracy of extracting the planting area of rice.关键词
