Research On Integrating Raster With Vector Methods Of Updating The Basic Land Use Map Based On 3S Technology

Integrating raster with vector methods of updating the basic land-use map based on 3S technology is becoming one of the most important developing direction in 3S application field; land-use and cover change field over the world. In this paper, I establish a set of updating the basic land-use map technology and flow after I go deep into studying the methods of updating the basic land-use map based on 3S technology. It is very important point that I bring forward some methods of change information automatic detected founding on land-use map unit, cross correlation analysis with multispectral image and object-oriented classification aiming at difference data and difficult identifying change information problems. And then, I compile the programme and practise validating to examine technics flow. Test proves it is keeping ahead, in reason, science and nicety. It has been successful applied in task of The Ministry of Land and Resources P.R.C and taken some benefit.
