中文摘要：

地质学属于数据密集型科学,并与地球科学面临的问题息息相关。已经收集的和将要收集的大量数字国土相关数据,由于科学研究的需要,正在不断加以检验和扩充。大数据时代背景下,中国国土资源数字化、信息化的战略行动具有深远意义,大数据的相关技术应用为实现地质工作的现代化和信息化提供了有效的支撑。重点介绍大数据背景下的＂地质云＂构建理念与方法,以及大数据在地学领域的应用。大数据为非结构化、半结构化的地质数据带来了新的处理方法与理念。地质云的构建旨在探索以需求带动的地质核心数据的应用,挖掘非结构化数据的新数据信息,以支撑国土资源管理决策。

英文摘要：

Geology belongs to the data-intensive scientific. A lot of digital data related to the geological and terrain have been collected and will be update, due to the need of scientific research, to better applied to serve the human activity, the data are more and more examined and expanded constantly, the data＇s number is increasing. The informatization strategy of the land resources in China has profound significance. This paper focuses on the establishment of the ＂geological cloud＂ under the back ground of the big data and the application of the big data to geological field. Big data technology brings new methods and ideas for unstructured, semi-structured geological data. The establishment of geological cloud purpose to explore the application of the core data of geological, find the new information by data mining from the unstructured data, for decision support in land and resources administration.
