地球科学数据共享

进入21世纪,随着计算机技术和网络技术的高速发展,使得人们利用网络获得各种数据成为现实,也使得地球科学数据共享成为可能。地球科学数据共享是时代的需求,为了实现地球科学数据跨系统、跨平台在不同硬件、软件平台下共享在数据层面上,必须制订地球科学数据共享的相关法规、政策,建立健全地球科学数据的采集标准、共享标准以及进行数据和用户分级;在技术层面上,需要选择适合地球科学数据特点的网络环境,以及开发处理海量异构数据的技术和元数据库,并需要确保数据的安全。

Study on the Geoscience's Data Sharing

Entering the 21st century, with the rapid development of computer technique and network technique, we can obtain any information through internet, and make geologic data sharing possibility. Human being needs share the geoscience's data in the contemporary era for researching and understand of something about the earth. Sharing the geologic data bothhard ware and software working on any system and platform. On the one hand, as for data aspect, we must not only establish the policy and rule for sharing, set up the criterion for collecting and sharing data, but classify the data and user. On the other hand, as for technique, we should select proper network setting; choose technique to deal with the different structure of the data, set up metadata for delivering data, and guarantee the data security.
