In August, the temporary joint venture formed by COTESA, Edef and Telespazio was awarded a job that is part of the project ‘Madrid Urban Mapping Update on Scales of 1:1,000, 1:5,000 and 1:20,000’ to be completed between 2017 and 2018 by the capital’s city hall.
With the use of innovative mobile mapping technology, the layout of all the city’s tunnels will be included for the first time ever and with a very high level of precision in order to offer useful information of great value for emergency services, mobility and underpass conservation.
This is the first time the City of Madrid is doing this type of mapping and it will include some 200 km of tunnels from which precise data on signage, facilities, topography, equipment, road surfaces, gauges and walls will be collected.
COTESA is beginning the work with a vehicle equipped with a system that includes a three-dimensional scanner with LiDAR technology (a laser with geology, seismology and atmospheric physics applications), 360º photographs, a global satellite navigation system, odometers (calculate the total distance covered) and inertial systems to obtain information with centimetric precision on underground roads.
The results of this preliminary work taking georeferenced images will make it possible for municipal technicians to measure and consult the 3D point cloud obtained for analysis and maintenance, control, stocktaking and decision making, among other tasks.
It’s a pioneer initiative in Madrid which may be replicated in any city in order to have more accurate municipal information on service infrastructures, assets and roads.
