Abstract:Crop area extraction by using remote sensing images has been widely used in the extraction of crop planting area, but the extraction efficiency is low and the accuracy can not meet the production requirements. Accompanying with the advent of high-resolution sensors, the fusion of multi platform remote sensing data is conducive to improve the accuracy of classification and dynamic monitoring. In this paper, taking the extraction of grain planting area in Juxian county, Rizhao city as an example, multi temporal and multi-source heterogeneous data have been integrated, grain planting area by using deep learning algorithm has been extracted, the complementary effect of multi-source data has been deeply excavated, and a method of extracting crop planting area by integrating multi temporal and multi-source geographic information has been puts forward. It will lay a foundation for the rapid and efficient extraction of crop planting area.
