It was nearly 20 years ago that the landuse map was made

which is inconsistent with the facts gradually and needs to be updated to provide accurate landuse information for the rapid development of the region. Having the advantage of the high resolution and spatial view

the SPOT5 image is taken as the suitable remote sensing data for updating the landuse map. Based the experimental study in Jiu Yuan district of Baotou city

we put forward a practical technology and method to realize the 1∶10000 landuse map updating. From the view of the users

we use the landuse map (DLG) and topography (DRG) to produce orthophotoquad image

and extract the landuse changing information from the overlaid maps composed by landuse map and the SPOT5 image. The uncertain information is further investigated by field work. The experiment show that the updating technology based on the SPOT5 image is more efficiency

economical and practical than the TM image based technology which were used before.
