| Abstract: | This paper studies a method of updating county-level land use database by taking Yanshi city for example. Changeable information is retrieved in the interaction process with the assistance of specialists after having the modified land use database overlapped and contrasted by the DOM of SPOT-5. Then, a detailed investigation is carried out to check the information. Finally, maps of detailed investigation are vectorized and connected with corresponding attribute data, and the topology relations are rebuilt,thus completing the updating of the database. |
