1:1万地形图高程注记点采集方法研究

The Research of 1 : 10000 Topographic Map Altitude Lettering Points Collection Method

通过对水准仪散点法、GPS-RTK高程和内业全数字摄影测量工作站三种高程注记点的采集方法进行系统的研究,力求找到既保证满足成图精度要求,又减少劳动强度,提高工作效率,并符合现实情况的一种准确、高效、经济的采集方法,为我省新一轮基础测绘顺利完成提供科学依据。

This paper researches the three altitude lettering points collection methods which are Level casual point method, GPS-RTK height, and indoor total digital photogrammetry working statiors Try to find an accurate, efficient, economy, and realistic collection method which ensures accuracy to meet the map and reduce labor intensity, improve work efficiency. The scientific basis is provided for the successful completion of a new round of basic mapping of our province.
