Evaluation of selected methods for extracting digital terrain models from satellite born digital surface models in urban areas [PDF]

, 2011
For the generation of 3D city models from satellite stereo imagery beyond the generation of digital surface models (DSM) from stereo data the next crucial step is the separation of urban 3D objects from ground.

Observing sea levels in the China seas from satellite altimetry

, 2018
Due to the threat of global warming, extensive studies of the natural and anthropogenic causes of sea level change have been performed. The use of satellite altimetry contributes enormously to such studies, especially where in situ observations are rare.
