| Abstract: | Acquiring accurate data of irrigated wheat land area and distribution timely can provide data support for water resource regu- lation and fighting against drought. This paper analyses the long - term wheat growing feature of Renmin Shengli Canal irrigation area using the data of HJ - 1 multi - temporal satellite, and studies the method of quick extraction of irrigated wheat land. The results show that distribution and area of irrigated wheat could be accurately extracted using the multi - temporal NDVI data of HJ satellite data be- fore winter and the accuracy is higher than 90%. |
