This article is dedicated to the extraction of 3D information using the matching between SAR and optical features. An external knowledge of a building map is provided. The proposed method to recover the building height is based on score optimization and works in two steps. First the ground height is retrieved allowing the suppression of many of the corner / wall reflectors. Then, an elevation is searched for each building. Some results are given on a test area.
