Abstract: In order to store energy, most of pumped storage power stations are located in mountainous areas with high elevation difference, usually with high vegetation coverage and less human activities. As hydropower design tends to be three-dimensional, the demand for real terrain is very urgent, and traditional measurement methods are difficult to obtain high-precision terrain data, especially in initial design phase of hydropower station. This paper describes how to use the LiDAR in the topographic surveying and mapping to provide 3D terrain for the subsequent three-dimensional design.

Key words: LiDAR, pumped storage hydropower station, topographic mapping, 3D terrain modeling
