Method of Quickly Determining Essential Observation Numbers in the Teaching of Surveying Adjustment
The essential observation number is the premise of establishing the surveying adjustment function model.In order to quickly determine the number of essential observations of the geometric model and solve the difficulty of calculating the number of essential ob-servations for students in the course of surveying adjustment,for the seven geometric models commonly used in surveying work,combi-ning the layout characteristics of the control network and the initial calculation data under different observation conditions,a general calculation formula for determining the essential observation number is proposed,and the correctness of the formula under different ge-ometric model conditions is listed and verified.The formula is simple in structure,easy to understand,and universal.It expands the application field of essential observations,enriches the content of methods for determining essential observations,and promotes the fur-ther development of survey adjustment theory and methods.
