Position.
With supplementary surveying equipment, the point cloud can be tied into plan and elevation control.
CLEVERSCAN / KNOWLEDGE & PRACTICE
Georeferencing the manhole point cloud
Position and elevation reference with additional surveying
POSITION
Georeferencing the manhole point cloud
CleverScan generates the geometric point cloud of the structure. Supplementary surveying equipment is required for plan and elevation reference. If it is integrated from the outset, inspection, geometry and spatial referencing can be combined in one workflow.
Practice & application
- optical condition documentation plus surveying
- capture of manhole wall and invert
- dense point cloud as a planning basis
- hard-to-reach or non-drivable structures
- as-built documentation, maintenance and rehabilitation planning
- spatial referencing with supplementary surveying equipment

Note: operating conditions, surfaces, shading and positioning influence the quality of laser data capture. Performance data must therefore always be assessed in the context of the specific measurement task.
Q&A
Technical questions
Is the point cloud automatically georeferenced?
No. Absolute position and elevation references require additional surveying equipment and suitable control points.
