基于EPS的测编一体化测图方法研究

Research on Integrated Mapping Method Based on EPS

介绍了EPS软件垂直摄影三维测图模块的功能,探究了从测图到编绘数据处理的一般作业流程;以某项目为例,将事先准备好的DOM和DEM数据导入EPS软件生成垂直摄影模型,然后加载垂直摄影模型和超大影像图,以二维和三维视图窗口为参考完成了地形图要素的采集与数据检查。实验结果证明:基于EPS的垂直三维测编一体化测图作业方法能够实现裸眼测图,可以直接输出符合基础地理标准规范的地形图,并且能节约大量的时间,在一定程度上摆脱了立体测图硬件设备的束缚,实现了随时随地测图和便捷化测图。

This paper introduces the function of vertical photography 3D mapping module of EPS software,and probes into the general operation flow from mapping to compilation and data processing.Taking a project as an example,the prepared DOM and DEM data were imported into EPS software to generate a vertical photography model,and then the vertical photography model and super-large image map were loaded.The 2D and 3D view windows were used as reference to complete the collection and data inspection of topographic map elements.The experimental results show that the integrated mapping operation method of vertical 3D mapping and compilation based on EPS can realize naked eye mapping,can directly output topographic maps conforming to the basic geographic standards and specifications,and can save a lot of time.To a certain extent,it can get rid of the shackles of stereoscopic mapping hardware equipment,and realize mapping anytime,anywhere and convenient mapping.
