基于矿区大比例尺地形图的简化研究

由于内容丰富、精度高,大比例尺地形图在社会生产中的发挥着越来越重要的作用。但是过多的地物使地形图显得冗杂,增加了使用的难度,降低了使用效率;因此大比例尺地形图在提供给各部门使用以前需要进行简化处理,消除图中冗杂的信息、完善数据间的拓扑关系,增强图的可读性及可利用性。本文以太行山某矿区地形图简化为例,介绍了大比例尺地形图的特点,同时浅析了大比例尺地形图的简化技术。结合实际生产进行了简化处理前后数据的对比,统计分析了处理前后数据的差异,本研究为同行之间开展类似研究提供了参考和依据。

Study on simplification of large scale topographic map based on mining area

Due to its rich content and high precision,large-scale topographic map plays an increasingly important role in social production.However,too many features make the topographic map appear miscellaneous,increase the difficulty of use,and reduce the efficiency of use;therefore,before the large-scale topographic map is provided to all departments for use,and enhance the readability and usability of the map.In this paper,the characteristics of large-scale topographic map and the simplification technology of large-scale topographic map are introduced,taking the simplification of a mining area topographic map in Taihang Mountain as an example.Combined with the actual production,the data before and after the simplified processing were compared,and the differences between the data before and after the processing were statistically analyzed.This study provides a reference and basis for similar research among peers.
