| Abstract: | A new method and technical flow to extract urban built-up area with remote sensing technology were detailed based on two different periods of Landsat remote sensing images which cover three cities of Suzhou,Wuxi and Changzhou.The two bands of TM3 and TM2 were transplanted into Normalized Difference Built-up Index(NDBI),and combined with NDBI,to extract urban construction land.The scope of the three cities'built-up area was gained with the method of built-up area definition which is suitable for remote sensi... |
