摘要
地图投影是GIS知识体系的重要组成部分,每个GIS软件都会涉及到该部分知识。Map GIS软件中的投影变换相比国外以及其他的软件更具有针对性,更符合中国的国情。该文以"用户文件投影变换"功能的具体操作为例,介绍其在地质线路图、柱状图中的应用,辅助该功能在投影图及地形地质图中大量钻孔的投入示意图,讲解Map GIS软件在地质基础图件中的应用,就如何利用Map GIS软件增加工作精度节省工作时间进行讨论。
Map projection is an important part of GIS knowledge system.Each GIS software will involve this part of knowledge.Projection transformation software not only has more pertinence compared with other MapGIS softwares, but also more in line with national conditions in China.In this paper,setting specific operation of ＂user files pro-jection transformation＂ function as an example,its application in geological circuit diagram and histogram have been introduced.Combining with the auxiliary function of the large drilling in geological maps projection and terrain into diagram,the application of MapGIS software based on geological maps has been explained in detail.How to in-crease work precision and save work time by using MapGIS software have been discussed as well.
