| Abstract: | Because of the diverse coast data, not only data models and formats but also data datums are different. So it is the basis for coast management and ship landing decision to eliminate these variances and to found unified expression of sea-land terrain model. In the paper, based on researches both at home and abroad, the main problems of sea-land data in tegration are analyzed, and then key techniques of unified expression of sea-land terrain are discussed, which lay the tech- nique basis for sea-land terrain model. |
