摘要
全国矿业权实地核查是我国矿产资源领域的一次重要国情调查,其中的测量工作主要通过控制测量、收集资料、实地检测、图件编制等方法,将各个矿业权不同时期、不同形式、不同坐标系、不同比例尺的地理地形图、地质矿产图、工程平面图、井上井下对照图等资料,统一以1980西安坐标系为基础,进行成果的汇总整理,并按照一定比例尺制作成图,最终建立数据库系统。本文以河南省某县级市为例,分别采用CASS 6.1系统、MapGIS 6.7系统,以及本院自主研发的"空间数据处理3.0系统"3种不同方法,对坐标转换的结果进行分析比较,最后对坐标转换的工序进行了优化设计,具有一定的参考价值。
On-site verification of mining right is an important national situation investigation in the field of mineral resources in China.The surveying work is,through control surveying,data collection,on-site detection,map compilation and other methods,trying to summarize and arrange the data of geographic topographic maps,geology and mineral maps,engineering plane maps,surface-underground contrast plans in different periods,different forms,different coordinate systems and different scales based on 1980 Xian coordinate system,then mapping them into maps in a fixed scale,and finally building a database system.This paper took a county-level city in Henan province for example,used three methods,which were CASS6.1 system,MAPGIS6.7 system and space data process3.0 system developed by the institute members themselves.Then it analyzed and compared their coordinate conversion reaults.Finally,it optimally designed coordinate conversion procedure with reference value.
