Application And Research Of Integration Between Multi-source Remote Sensing Image Data And GIS

Based on multi-source monitoring information in Taihu Lake,supported by RS(Remote Sensing) and GIS(Geographical Information System) technology.A water environment monitoring information management system is developed and the system framework is expounded,components and functions of system is comparatively particular introduced.The technology and integration of RS and GIS are discussed for their inherent meaning and relationship to each other.The 'combine top' models for the integration of RS and GIS are presentedJn GIS environment,the monitoring information in water environment is managed.The analyse methods which based on RS and GIS integration technology are presented for dynamic monitoring water environment in Taihu Lake.The method of RS grey image data with practical monitoring data can totally appraise the water quality in quickly and effectively.The development process and composition and function of GIS are introduced and summarized,advantages of the GIS technology used in space analysis and water environment data management are well illuminated.Multi-source RS image disposal and data fusion are summarized,also analyse image fusion technology used in monitoring water environment.RS monitoring can provide big area of water quality information,the characteristic of RS is timing and prompt and permanence.The information which provided by RS is not assimilate with general monitoring water quality.GIS dispose space data is the efficiency tools,it can dispose and analyse the RS which provide a great deal of space information in quickness.this predominate work efficiency and economy benefit.The integration of RS and GIS shall enhance monitor and analyze water environment,combining with research actuality of RS and GIS,research progress of the integration of RS and GIS used in water environment,the possibility and necessity of the integration of RS and GIS are testified.A preliminary attempt and explore of monitoring water quality,the technology and integration of RS between GIS,it can be useful reference for the domain of research work.
