摘要
以某测区精密水准测量为例,论述了水准测量的布网方案、外业观测及内业数据处理等内容,通过图表对平差结果进行精度分析,得出影响精密水准测量的主要原因以及提高水准测量精度的方法措施。
Taking a precise leveling survey area,for example,discusses the distribution network level measurement,field observation and data processing etc,Chart of results through the adjustment accuracy analysis,the main reason of precise leveling and improving the standard of measurement accuracy measures.
