Abstract：The wide variety of marine environmental objects and multi-resolution scientific data bring challenges to the current approaches of data storage and processing. This paper proposes a unified architecture of marine environmental field data storage and organization for tiled map. The diversified multi-resolution field data can be organized into multiple blocks with the unified dimensions after stratification and partitioning. These blocks can be stored and managed in the architecture by index encoding. Its application to the service platform for marine environmental forecasting information shows that the proposed method supports efficiently the heterogeneous data integration, temporal-spatial statistical analysis and visualization.
