HD Maps and Usage of Laser Scanned Data as a Potential Map Layer

Intelligent mobility around us evolves every day. But this evolution can be only as progressive as the data it is based on. First part of this paper is focused on an overview of high-definition (HD) maps and their adoption for use in various sectors of society. The HD maps consist of separate geospatial representations, for instance - road networks, buildings, technical infrastructure, soil structures or landscape profile. To be more specific HD maps are maps which are overlaid with additional information - in a form of description or graphic representation in 2D or 3D space. Unlike conventional maps, accuracy of HD maps ranges from centimeters to millimeters, and this is a fundamental difference between conventional maps. We present the scope of usage of HD maps and known limits. Practical part of this paper focuses on usage of laser scanning technology to create detailed scan of potholes. This type of data could serve as a potential HD maps layer.
