Three-Dimensional Integrated System for Multi-Source Heterogeneous Data

Abstract

With the increasing standards and requirements of earthquake emergency response, higher requirements are put forward for data organization, management and display. Because different types of data have different storage management and processing methods, and data processing and data display have different requirements for the same data organization structure, as well as the poor correlation among heterogeneous data, how to construct a comprehensive three-dimensional integrated system for multi-source heterogeneous geospatial data in the era of big data. It is a challenge for seismologists to provide quick support and guarantee for earthquake emergency response and decision-making. In this paper, the organization, integration and display of multi-source heterogeneous data are studied, and a three-dimensional integrated system of multi-source heterogeneous geospatial data is built to serve earthquake emergency. The system realizes efficient organization, fast query, display and download of multi-source heterogeneous seismic data.
