Abstract In recent years, the ecological problem of abandoned quarry is increasingly noticed by national government. Ecological restoration of abandoned quarry has been an important zone of urban ecological construction in China. The regional topographic survey is the basis of ecological restoration.Imaging total station measurement as a new topographic survey technique developed in recent years has been widely used in the topographic survey of abandoned quarry. Based on the introduction of measurement principle of imaging total station made in Topcon Corporation in Japan, the entire process of topographic survey and post-mapping was practiced in an instance. Practice has proved that the imaging total station measurement technology have advantages with simple operation, high speed, and high precision. In particular, the non-prism measurement without a prism light reflection greatly improved the efficiency of the topographic survey, and protect the safety of the surveyors at the same time. This method can be applied to topographic survey in tough area where the conventional measurement is difficult to achieve.
