基于GIS的泥石流灾害系统中数据集成方案

Data Integration in GIS-based Mud-rock Flow Disasters System

为增强泥石流灾害数据可视化管理系统的兼容性，分析了多源数据集成技术，讨论了泥石流灾害工程中多来源数据和多格式数据的问题，以及在应用系统中对多源数据集成处理的要求，提出以Super Map结合VC＋＋6．0在基于GIS的泥石流灾害工程应用中实现多源数据集成的一种解决方案，实现了系统中对多来源、多格式数据的集成功能，从而达到了系统能直接访问、处理不同来源空间数据的目标。

To promote the compatibility of the visible data management system of Mud-rock flow disaster and to realize the direct visit and processing of data from different sources, this article analyzes the integrated technology of multi-sourced data and discusses the problems of multi-formatted data and multi-source data in the project of Mud-rock flow disaster as well as the requirement for processing multi-sourced data in application system. In addition, it provides a solution by combining SuperMap and VC ＋ ＋ 6.0, based on the integrated multi-source data in the project of Mud-rock flow disaster. It also realizes the function of integrating multi-sourced and multi-formatted data, and thereby attain the aim of direct visit and processing space data from various sources.
