In order to manipulate the marine data for statistically,a Raster-based Spatiotemporal Hierarchical Data Model(RSHDM) was designed for the nature of marine phenomena or marine fishery management.Based on the data model a spatiotemporal data warehouse for marine fishery management has been developed.Our practice shows that the RSHDM can provide aggregation data for fishery management at each level.
