3D Mapping is a recent development in survey technology. It uses a 3D scanner to measure and digitise real-world objects and structures.
Currently, there are various types of 3D scanners each based on different technologies such as photogammetry, Simultaneous Localisation And Mapping (SLAM), and static laser scanning. Each of them, takes a different approach to 3D mapping and has their own limitations, advantages and costs.
Regardless, the resulting product would be a 3D digital model of the object or structure of interest. This model can then be used for a wide variety of applications such as architectural/ engineering design, as-built, conservation, inspection, Building Information Modelling (BIM), volumetric/ dimensional analysis, and even Virtual Reality (VR) simulation.
Why is it important?
As technology progresses, the demands of clients evolve as well. Building designs become more complex and integrated, and the ability to design and communicate in three dimensions becomes ever more crucial. Thus, it is essential to have a surveyor equipped to capture the data you require.
