Extraction of Urbanized Area in Beijing Based on Skewness Texture

LI Xi et al(School of Remote Sensing and Information Engineering,Wuhan University,Wuhan,Hubei 430079)  
In Beijing,spectrum of some cropland is very similar to that of urbanized area,so it is hard to extract the urbanized area only by spectrum.Skewness texture was proposed to separate cropland from urbanized area.Assisted by spectrum and elevation data,the urbanized area was extracted efficiently.Accuracy assessment based on many samples showed that Skewness could improve the classification accuracy significantly.
