Dimensional control surveys utilize surface independent geomatic technology which allows them to be conducted in or on non-level environments surfaces and moving or vibrating structures. As the instruments used to conduct these surveys do not need to be level they are essential in the off-shore industry where many platforms are not fixed and are subject to continuous or intermittent movement. This type of survey is utilized in a wide range of applications such as 3D capture, topographical surveys, alignment surveys, replacement pipe-work, mining surveys, structural steel surveys, drill rig alignments, ship repair and building, laser scanning and 3D modeling.
