基于GIS的多源异构数据整合方法研究

摘要

Due to the objective existence and integration difficulties of multi -sourced heterogeneous data , there exist various issues for data management and sharing .Base on the GIS technology , this pager which provides a hybrid approach for data management and sharing mainly study on the following aspects:data classification , data directory creation , data reading , data extraction , data symboli-zation and output .%多源异构数据的客观存在性与数据无缝融合的困难性，使得空间信息数据和业务过程中其他文件的有效管理与共享存在很多问题。本文基于GIS技术从多源异构数据的分类，数据目录树与各类数据节点的创建，数据的读取，数据的提取，符号化与出图等方面进行了研究与实验，为多源异构数据的管理与共享提供了一种方法。
