Since the remote sensing data of MODIS has some advantages of short detection period, wide coverage and open access, it is suitable for large-scale, dynamic agricultural remote sensing monitoring. According to the application requirements of winter wheat acreage extracting in Huang- Huai region, this article analyzes the features of MODIS data and phenological characteristics of crops. Three kinds of MODIS data and five remote sensing indices are used in winter wheat acreage monitoring. The results show that the five-day synthetic MODIS data product has a better extraction accuracy, and the indices of NDVI and NDWI are better for crop monitoring in early phase of winter wheat.
