摘要
Abstract
The elevation systems in measurement and their transformation relationship were introduced, and the GNSS level models were also introduced briefly. The precision of GNSS leveling surface fitting in mountain area was analyzed through examples, and the GNSS level accuracy and peripheral point accuracy were assessed, and some valuable conclusions were obtained.关键词
