Abstract: This paper probes into the method for updating land use map at a scale of 1∶10000 based on hyper-spectral and high resolution Images. Firstly, under the control of land use types from former land use database, a land use/land cover map is acquired by spectral matching classification method using OMIS-I Airborne Imaging Spectrometer Data in Yixing. Secondly, changed areas are detected by image math operation between class map and former land use map. Thirdly, using image merged by hyper-spectral and SPOT-5 pan band data as base map, leading by former land use database at a scale of 1∶10000，vector data among dubious area are updated in a mutual computer-aid mode. Then, in order to validate the dubious changed areas，a field investigation is done with the help of GPS. Finally, land use database is updated when the data are amended indoors according to investigated results.
