基于文件的矿图要素分类与分层研究

摘要

在充分调研我国矿图绘制技术和方案的基础上,讨论了矿图的种类、性质、特点及其相互关系,剖析了当前绘制技术和方案中存在的问题和弊端.以图形数据冗余最小、要素表达一致、绘制精度一致、图形更新同步且与GIS数据融入为目标,提出了基于文件的矿图绘制方案.对矿图要素的分类与分层表示,以矿图为目标的图层优化组合进行了研究.%The Classes, properties and features of mine maps are discussed and the problems and the drawbacks are analyzed based on the plenty of investigation for the mine mapping technology and scheme.For minimizing the redundancy of map data and ensuring the consistency of presentation for map elements and mapping precision, the mapping technology based on file was proposed. The presentation of classifica tion and stratification for mine map elements and the optimal combination of map layers were researched.
