Retrieving Vegetation Cover by using BP Neural Network based on 'Beijing -1' Microsatellite data

摘要

This paper presents a BP neural network method to retrieve vegetation cover of the Drainage basin of Miyun Reservoir based on the new remote sensing data - "Beijing-1" microsatellite data. And the retrieval result was compared with the one retrieved by the traditional methods. The compared results showed that for vegetation cover retrieval in mountainous areas, neural network has the advantage of precise simulation of non-linear transmission over traditional methods, especially for mountainous vegetation cover retrieval which traditional methods usually fail.
