摘要
本文作者在实施"长沙市地质资料信息服务集群化和产业化资料收集与标准化工作"项目过程中,针对工勘资料中普遍存在的地质钻孔坐标空间参照不统一的问题,在分门别类分析各类坐标空间参照系特点的基础上,结合对国内已有成果的研究,摸索出一套利用Map GIS软件作为实施平台,采集多源空间坐标数据并统一转换到西安80坐标系的有效方法。
During the process of implementing the project, the author found that the coordinate spatial reference system about drills isn't generally same in a great many of reports about prospecting and surveying. After analyzing on all kinds of projected coordinate system and combining with many internal achievements, the author worked out a set of working method---using MAPGIS software as the executing platform, for uniformly transforming the multi-source spatial coordinate system data into the Xi'an 80 coordinate system.
