%X This paper presents a two-layer based enhanced map that can support navigationin urban environments. One layer is dedicated to describe the drivable road with a specialfocus on the accurate description of its bounds. This feature can support positioning andadvanced map-matching when compared with standard polyline-based maps. The otherlayer depicts building heights and locations, thus enabling the detection of non-line-of-sightsignals coming from GPS satellites not in direct view. Both the concept and the methodologyfor creating these enhanced maps are shown in the paper.
