GPS静态测量与四等水准测量高程精度对比分析
Comparative and Analysis Elevation Precision of the Static Measurement of GPS and Fourth Leveling Surveying
摘要
Abstract
The current GPS technology gradually become mature and has been widely used in engineering construction, the GPS plane precision is accurate but elevation precision can＇t meet some engineering requirements, high standard of accuracy engineering is mostly set by the leveling surveying. The elevation of GPS measurement and the leveling surveying based on a project is analyzed. By comparing both observation data, the conclusion is got that GPS fitting elevation can instead of the leveling surveying in flat small range.关键词
