This paper presents the participation of the SIC to the EuroSDR contest (European Spatial Data Research; formerly known as OEEPE) about road extraction. After presenting the framework of the EuroSDR contest, our approach for road extraction is described. It consists of a line detector based on edge detection using a straightness constraint obtained from geometrical moment to filter out non-straight segments. Those segments are then filtered according to the NDVI (vegetation index) since roads are made of material different from vegetation. Resulting figures about the completeness, correctness and localization precision of the road segments are discussed for the EuroSDR data, and compared to the results of other challengers participating to the contest.
