基于MapGIS和明码文件的数据集成

Data integration based on MapGIS and ASCII code files

基于MapGIS的数据集成包括数据转换、数据标准化、数据融合及相关研究,综合现有研究认为,数据转换的研究非常深入,在数据标准化和数据融合等方面还有提升空间。本次研究中,以复杂且使用广泛的地质图为例改进数据标准化方法,实现了一次完成数千个地质体规范标注和填色;分析常用数据融合的不同方法的适用条件,补充完善后建立数据融合技术流程;编写明码文件实现小煤柱的批量制作。研究结果表明,改进数据标准化方法、建立数据融合技术流程及充分利用明码文件,能使数据集成的效率大幅提高并拓宽解决问题思路。

Data integration based on MapGIS includes data conversion,data normalization,data fusion,and related research.A synthesis of existing research suggests that data conversion has been intensively studied,while there is a lack in studies of data normalization and data fusion.This study improved the data normalization method based on the complex and extensively applied geological maps,achieving the normalized annotation and color filling for thousands of geobodies at one time.A technical process for data fusion was established by analyzing the applicable conditions of various commonly used methods for data fusion and making some supplementation.Besides,ASCII code files were prepared for mapping small coal pillars in batches.The results of this study show that improving the data normalization method,establishing the technical process for data fusion,and making full use of ASCII code files can significantly enhance the efficiency of data integration and broaden the mind for problem solving.
