补充资料：几何水准测量
水准测量又名“几何水准测量”，是用水准仪和水准尺测定地面上两点间高差的方法。在地面两点间安置水准仪，观测竖立在两点上的水准标尺，按尺上读数推算两点间的高差。通常由水准原点或任一已知高程点出发，沿选定的水准路线逐站测定各点的高程。由于不同高程的水准面不平行，沿不同路线测得的两点间高差将有差异，所以在整理国家水准测量成果时，须按所采用的正常高系统加以必要的改正，以求得正确的高程。我国国家水准测量依精度不同分为一、二、三、四等。一、二等水准测量称为“精密水准测量”，是国家高程控制的全面基础，可为研究地壳形变等提供数据。三、四等水准测量直接为地形测图和各种工程建设提供所必需的高程控制。
