Abstract  

Orthophoto imagery has been widely used in the remote sensing study.However,due to the use of incomplete terrain model,phenomena such as surface features dislocation and block inevitably occurred in the traditional orthophoto has seriously affected the quality of the project and mapping accuracy.This study discussed the principle of using DBM (Digital Building Models) and DEM (Digital Elevation Model) for the true orthorectified imagery and the key technologies of workmanship in producing the true orthorectified remote sensing image.In theory,the True Orthoimage map,produced by DSM and DBM,detected and compensated by block area,could completely solve all of problems of traditional Orthoimage map.It is the best choose of detecting changes,collecting surface features and producing three-dimensional landscape.The advantage is obvious.But,relative to Simple treatments of traditional Orthoimage map,notable feature of Ortho-corrected map is enormous amount of data operations.On the other hand,difficulties and costs to get DBM/DSM is still expensive,so the using of the True Orthoimage map is limited in city.

Key words:  True orthocorrection      DBM      DEM      Visibility analysis
