| Abstract: | Based on the experience and achievement of theChina Digital Ocean,the classification plan for Marine data elements is made,which can be classified into five,including marine point elements,marine line elements,marine polygon elements,marine grid elements and marine dynamic elements.With the technology of features and object-oriented method,a spatial-temporal data model is proposed,which can be applied in large information system engineering like Digital Ocean,discusses the application of spatial data model,... |
