Scanned maps contribution to the aerial images interpretation allows to consider as possible the complete resolution of the geographical objects depicted in a scene. But as all symbolic documents, maps are submitted to unavoidable distortions during their conception process. We present a method to estimate and characterize these alterations in the road network case. An a priori model of the distortions is first built, based on the cartographic drawing rules. Then, a control of the map data is operated with a ground reference given by an aerial image. Finally, a prediction model is established from the results. It gives the roads aspects in the image with tolerance thresholds and alerts the operator when the map has a low reliability.
