Digital ocean prototype system is a key part of the China digital ocean information basic framework and the basic integration platform for China ocean information management and application. The purpose of marine environment data warehouse is to provide comprehensive and multiple marine information services. This paper proposed distributed marine environment data warehouse construction, and gives...
The marine environmental data has a strong temporal-spatial characteristic. The ocean is always changing. In terms of time scale, marine environmental information is characterized by its climatology-scale variation features (i.e. year, season) and weather-scale variation features (i.e. day, hour). The multi-time scale and time-varying characteristics of marine environmental data products bring foreword...
Marine current is a typical spatio-temporal process. Through numerical simulation and model calculation, a large amount of 3D data fields of marine phenomenon is obtained, spatio-temporal model can effectively store, organize, manage and improve the spatial and temporal semantics of geographic objects. It can more accurately reproduce history, track changes, and predict the future. Temporal database...
Based on the study of output data characteristics of storm surge forecast model and existing scientific data visualization methods of these data, this paper carries on a preliminary study on the WebGis-based storage and visualization of these data, and designs and implements a storm surge disaster visualization web application system based on sphere. This system provides a more intuitionistic method...
Nowadays, there are increasing amount of data fields of tide and tidal current gained from ocean dynamical environment real-time stereo monitoring platform, model calculation and numerical simulation. Collaborative visualization of these data fields on the internet is becoming increasingly important for the utility of data. In this paper, we summarize the characters of tide and tidal current data...
As a macro complex systematic engineering, the Digital Ocean project is an ongoing task in china. The mission of the Digital Ocean is to build an interactive network information system based on a three-dimensional globe. The Digital Ocean can help provide integrated information on historical, current and future states of ocean and coastal zone. This paper addresses the architecture of Digital Ocean,...
