A project to revitalise the Isle of Man’s capital town Douglas is benefiting from detailed 3D survey data captured by the mobile laser mapping system StreetMapper. The vehicle based laser scanning system was used to survey an area of central Douglas incorporating the beachfront promenade. The millimetre accurate measurements collected by the StreetMapper system will be used to support ambitious regeneration plans including the relaying of lines for the historic Douglas Bay Horse Tramway, revised seafront parking and a project to enhance the appearance of both the footpath and roadway in the popular resort.
‘I truly believe that StreetMapper has revolutionised surveying on the island,’ commented Alan Donnelly, Assistant Borough Engineer at Douglas Borough Council. ‘It’s quick; collecting vast amounts of data in a fraction of the time it would take using traditional surveying techniques, and the data is accurate and easy to use.’ He continued, ‘The data captured by StreetMapper will allow us to clearly communicate regeneration plans, illustrating potential schemes to stakeholders in order to secure funding and approval and liasing with businesses and residents.’
The StreetMapper system completed the survey along Douglas seafront in a matter of hours without any real disruption to other road users and during normal working hours. The system captured millions of individual measurements documenting existing infrastructure and assets on the highway and footpath and recording detailed mapping of building facades and other structures.
StreetMapper, which is a joint development between UK based 3D Laser Mapping and German based guidance and navigation specialist IGI, has been specifically designed for the rapid 3D mapping of highways, runways, railways, infrastructure and buildings. Using vehicle-mounted lasers offering a 360-degree field of view StreetMapper enables high precision mapping to a range of 300 metres, a capacity of 300,000 measurements per second per sensor and recorded accuracies in independent real world projects of better than 10 millimetres.
