Research On Urban Large-scale Topographical Maps Updating By Using Of High Resolution QuickBird Remote Sensing Images

The QuickBird images is the highest resolution images in commercial circle in the world ( the resolution of QuickBird reached to 0.61 m ) at present .The application of QuickBird is very wide ,as the main section of city basic spatial information , this paper carried out several studies from QuickBird images processing , the building of multi-scale images database to urban large-scale topographical maps updating as follows:1 The research focus on the theory and method of QuickBird remote sensing images geo-correction ,on the technical procedure and method of QuickBird images ortho-correction based on DEM data so as to improve images correction precision , image correction precisions of QuickBird under two model combined with corresponding tests are compared and analyzed .2 The multi-scale images database of high resolution QuickBird images is builded by using of ortho-images ,and the remote sensing images browsed system of Fu Xin city based on Mapobjets (Its' abbreviation is MO) is setted up . The system has the characteristics of fast browsed ( can browse quickly total Fu Xin city ) and integrated ( the vector data images data and toponym etc. attribution data are integrated ) ect. So the system is widely applied in city planning communication planning the management and monitor of land using the investigation of city afforest coverage and the evaluation of city environment areas etc.3 The paper give out a complete technical procedure and method of urban large-scale topographical maps updating based on QuickBird ortho-images , and the corresponding tests are given too , and obtained credible precision .All in all , build up images database which is the main part of city basic spatial information data utilizing QuickBird ortho-images , people canachieve high work efficiency, save work time, get more veritable products, and obtain high precision etc. while using QuickBird high-resolution remote sensing images which Ortho-rectified to renew urban large-scale topographical maps , It is an effective method to update large-scale topographical maps by using of QuickBird high-resolution remote sensing images at present.
