New System of Construction Survey

各种电子测速仪都可用于控制测量，因此，利用这些仪器提出了一些新的控制测量系统。控制测量最简单的方法是建立一系列单行四边形网，在其中只设置一半测站，观测角度和长度。数据采集器对于放样工程和细部测量以及控制测量是有用的。提出了一种特殊的数据采集器。该系统的设计目的是计算和记录根据预先指定的观测程序进行的测量数据。在上述测量工作中，小而薄的角反射器是有用的。自动化测量的进展需要考虑特殊的摄影测量方法。

Various kinds of erectronic tachymeters can be applied to control surveys, so some new systems of control surveys are presented by use of the above instruments. The most simple network for control survey is to construct a chain of single row quadrangles in which a instrument is set only a half of stations and angles and lengths are observed. A data collector is usefull for setting-out works and detail surveys, as well as control surveys. A special data c-llector is proposed. That is designedso as to compute and record the survey data which are obtained by carrying out according with a previously assigned observation program.Followings are also proposed. In these survey works above, small and thin corner reflector is usefull. Special photogrammetric method is to be considered for progression of automatic surveying.
