Study on China Digital Ocean Prototype System

Abstract

As the related theory and technology of digital earth has been evolved since the concept of "digital earth" put forward by U.S. Vice President Al Gore, and more and more attention has been paid to ocean exploration and usage around the world in recent years, China ocean administration, together with oceanographers, proposes the "Digital Ocean" program from the state ocean development strategy point and puts it in the HI-TECH Research and Development Programs. "Digital Ocean", which comes from digital earth, has no exact definition currently and will be a large complicated project because it refers to many other technologies and methods such as wideband network, satellite remote sensing imagery data acquisition, mass data store and compression, interoperability, scientific computing, distributed objects, and virtual reality, spatial data warehouse, metadata database and Web GIS etc. China Digital Ocean Prototype System (CDOPS) which is the kernel part of "Digital Ocean", is designed and constructed tentatively. It provides a visualization, presentation and spatial analysis platform for ocean three-dimensional monitoring data and information. Ocean administrations, professionals, military departments and common users will benefit from that system. In this paper, one kind of understanding of "Digital Ocean" in China is introduced firstly. And then the architecture of the CDPOS is put forward. In addition, the design and preliminary realization of the 9 sub-system functions are presented. At last, some key technology problems faced in constructing CDOPS are discussed.

Creating Informal Learning in Ocean Museums in China: A Case of Shenzhen Shekou Aquarium

“…According to Zhang et al (2011), there have been worldwide attempts to enhance ocean observation and data sharing, including the Integrated Ocean Observing System, Google Earth, and KML generators like Yasuko. One particular project, CDOPS (Liu et al, 2009), has caught the attention of the author, who wishes to invest a grant in it. The following is its framework of it: Figure 1.…”

“…The framework of CDOPS CDOPS, unlike China Digital Science and Technology Museum (CDSTM), is designed to facilitate genuine interactions instead of solely relying on online interactions (Dong et al, 2011). Liu et al (2009) described CDOPS as a system supported by technology that accepts the analysis, evaluation, and manipulation of ocean data through visual visualization. This technology is similar to Skyline's TerraSuite software.…”

Recent progress of marine geographic information system in China: A review for 2006–2010

“…Sun et al (2008) conducted a research on the basic principle and technical frame of 'Digital Ocean', and provided a solution to ocean information management. Liu et al (2009d) gave one kind of understanding of 'Digital Ocean' in China and put forward the architecture of the China Digital Ocean Prototype System (CDOPS). In addition, they presented the design and preliminary realization of nine sub-system functions.…”
