地质大数据应用与地质信息化发展的思考

Thinking about the application of geological big data and geological information development

地质工作经过长期积累形成了的海量的地质资料与数据,具有重要的价值。地质数据具有多元(源)、异构、时空性、相关性、随机性、模糊性和非线性等特征,具有大数据特点,属于大数据范畴。由于地质调查工作和信息技术发展的融合,促进了地质大数据应用与地质信息化发展,地质信息化进入基于大数据分析与大数据应用的数据驱动新时代。本文分析了当前地质大数据技术及其应用,提出对地质大数据整合集成,对多来源、多模态、多时态数据的相关性分析、数据挖掘与关联建模,实现基于大数据的可视化与智能化。对地质大数据支持下的地质云平台构建、地质大数据应用服务系统和标准化建设的三要素,进行了探讨。

Massive geological information and data have formed by the long term accumulation of geological work,which has important value. It has the characteristics of big data and belongs to the category of big data, Geological data, which has many features such as multivariate （Multi-source）, heterogeneous, temporal,relevance, randomness, fuzziness and nonlinear. Integration of geological survey and information technology has promoted the development of application of big data and geological information, and geological information goes into a new era of data-driven which is based on big data analytic and big data application. This paper analyzes the current geological data technology and its applications, and proposes to integrate geological data integration, meanwhile it conducts correlation analysis, data mining and associated modeling about multi-source, muhi-modal and multi temporal state data. Finally, it implements the visualization and intelligent, based on big data. Besides, this paper also has discussed 3 elements supported by geological big data, which include geological cloud platform building, geological data application system and standardization of construction.
