Study on Post Processing Technology of Extracting Data of Soil and Water Conservation Measures by Applying High Resolving Power Satellite Images

The post processing method of remote sensing classified images is of important influence to extracting precision of the data of different types of soil and water conservation measures during the process of data extraction by applying high resoling power satellite images.It verifies the precision of area with various measures by using 2.5 m satellite image data of spatial resolution,in the light of the data extraction of soil and water conservation measures in the gullied rolling loess area and using different parameters of clustering process.It is better to select parameter value of 6×6 pixels of the minimum spot while using Spot 5 high resolving power satellite image for remote sensing classification of soil and water conservation measures based on integrated consideration of spatial and image characteristics of soil and water conservation measures.
