大数据环境下数字填图数据集成服务技术

应用数字填图技术形成了大量地质填图图幅数据，这些数据空间结构化和非结构化特征并存，如何在网络环境下提供高效的数据服务是急需解决的一个难题。大数据技术的发展为数字填图、数据集成服务提供了一种新的途径。通过对数字填图数据特征的分析，在研究地质调查信息网格大数据处理框架的基础上，提出了结构化和非结构化数据相结合的有序化组织管理、发布与服务方法，并对关键技术进行了研究与试验，取得了良好的效果。

Data integration and services of digital geological mapping based on big data

A large number of geological mapping data have been formed from application of digital geological mapping technology. They include spatial data and unstructured data. The problem as to how to provide effective network data-services is an issue that should be resolved urgently. The technology of big data provides a new method for data integration and services. In this paper, the authors selectively analyzed the characteristics of the data formed from digital geological mapping, and investigated the data processing framework of big data based on Geological Survey Information Grid. On such a basis, a method for data management, publishing and service was proposed, in which spatial data and unstructured data are integrated effectively. Experimental results show the feasibility of this method.
