The Application Research About LUCC By RS, GIS And GPS Technology

At present incorporated integration of "3S" technology (Global Positioning System, Remote Sensing, Geographical Information System) which take as obtaining, storing and managing, updating, analyzing and using of space information. RS,GIS,GPS being as foundation of incorporated integration of "3S" technology, come into being a new integrate technology by using relation part technology of them and other high technology.(1) Supported under RS and GIS , through remote sensing image digital processing, distill land uses information. Building up datebase of LUCC supporting at Geographical Information System, and overlay, colligation. Finally discuss frame of land uses information.(2)Integration of "3S" technology not only obtain and analysis spatial data in time and reliability, but also offer a computer information system through RS obtaining information, using GPS orientation, supplement and GIS dealing with information of programming and supervise of soil resource. Using integration of "3S" technology can supervise and study land uses mode and land uses degree. Analyzing character of space-time of LUCC.(3)As remote sensing image having characteristic of strong facticity, great information, amplitude area, great acreage, strong generalizing, easy finding out general picture. Apply studying change of land uses can improve precision of surveying and level of cartography.(4)Airbore remote sensing possess strong phenomena. It is very necessary for analyzing that can supply repetition date at short time. Using multi-temporal information, contrasting analysis differ of season and year, it can enrich standard of land uses sort.
