Second, the data checking and correction process, to understand the various sources of measurement error, its three main areas: equipment error (determined by the instrument itself, is an objective source of error), observation error (due to the technical level personnel a result of belonging to a subjective source of error), external influence error (subject, such as temperature, atmospheric refraction effects of external factors such as these factors are also constantly changing and difficult to control, belonging to a variable source of error).
其次,在对数据的检查和矫正的过程中,明白了各种测量误差的来源,其主要有三个方面:仪器误差(仪器本身所决定,属客观误差来源)、观测误差(由于人员的技术水平而造成,属于主观误差来源)、外界影响误差(受到如温度、大气折射等外界因素的影响而这些因素又时时处于变动中而难以控制,属于可变动误差来源)。
