StreetMapper maps Sweden’s roads


The laser surveying project is being managed by WSP, who is using 3D Laser Mapping's StreetMapper system to create detailed 3D models of the highway network across Sweden.

StreetMapper is a joint development between 3D Laser Mapping and German guidance and navigation specialist IGI. After successfully trialling the system last year, WSP is now using it in a live project to map 350 km of highway network.

The system uses a series of vehicle mounted lasers combined with an on-board positioning system to capture highly detailed and accurate measurements of the road surface, roadside assets and associated features.

StreetMapper uses laser scanning technology to capture highly accurate measurements at speeds of up to 70 km/h. Each scanner has a range of 150 metres, an 80-degree field of view and can capture up to 10,000 measurements per second. When combined with an on board GPS and Inertial Navigation System (INS), StreetMapper can achieve positional accuracies of up to 3 centimetres.

The StreetMapper 3D models will be delivered by WSP to the Swedish Road Administration to support road construction projects.
