3D laser surveying delivers extremely precise results in a short time, both in preparation for construction work and for the three-dimensional recording of an existing building stock. Especially over large distances or with old buildings such as those in Munich, this architectural surveying technology is considerably superior to manual measurement. With the help of photo panoramas, an accurate overview of the surroundings can be created and planned buildings can be visualised in their setting, so that preparatory construction measures can also be taken more quickly.

With a population of over a million, the city of Munich is characterised above all by its numerous buildings, which often makes complex topographic and boundary surveys difficult. Nevertheless, the statutory distances must be observed.
If required, three-dimensional laser scanning can also be optimised with drones and supports you in meeting documentation obligations, for example by entering buildings in the cadastral map.
Coupling the laser scanners and cameras with drones makes aerial land surveying far more cost-effective and flexible than with other airborne means.
Depending on the object to be surveyed, specific laser scanner measuring methods are used. When the Earth’s surface or the building structure of entire Munich districts is surveyed with 3D laser scanning, the pulse measurement method is suitable. Here, the lasers can measure distances of 1,000 metres with millimetre accuracy.
In this way, the laser scan captures, for example, important infrastructure information for urban planners or identifies suitable locations for solar power plants. For smaller objects, the phase comparison method helps to determine the exact dimensions. Compared with the frequently used pulse measurement method, the laser measuring device records ten to fifty times as many measuring points per second and also works considerably faster.
Applications for 3D laser scanning in Munich
Surveys frequently have to be carried out in the field of risk management. The structural stability of taller buildings and bridges can also be checked with a 3D laser scanner, as even the smallest subsidence or changes in alignment are detected. Based on the results of laser-based architectural surveying, long-term protective measures or evacuations can therefore be initiated.
Furthermore, terrestrial surveys can be used to determine the flood risk. Modelling with the CAD program provides an accurate overview of the areas at risk at certain flood levels. The precise visualisation can also be used to determine the necessary locations for flood embankments or for establishing natural floodplains.
For existing buildings on which renewable energy systems are to be installed, 3D laser scanning can be used to calculate the exact facade survey and to factor in shadows cast by trees or buildings from the point cloud.
This is because terrain surveying by photogrammetry or laser enables true-to-scale visualisation, which captures more than just the structure of the ground.
In this way, the three-dimensional laser scan, with the help of the point cloud and the millimetre-accurate facade survey, makes it possible to achieve the highest potential through the size and arrangement of the solar thermal and photovoltaic modules.
