全站仪大比例尺数字化地形测量精度研究

摘要

Taking the school topographic survey in Lvliang Coal Industry School as an example,through the comprehensive application of total station and CASS7. 0 mapping software,elaborated the main principles and steps of digital topographic mapping,including measuring area situa-tion,mapping control survey,scattered collection and CASS7. 0 mapping,finally put forward the effective measures to improve the accuracy of digital mapping.%以吕梁市煤炭工业学校校内地形测量为例，通过全站仪与CASS7.0成图软件的综合应用，阐释了数字化地形测图的主要原理及步骤，包括测区概况、图根控制测量、碎步采集和CASS7.0成图，最后提出了提高数字化测图精度的有效措施。
