Challenge
More than 12 km of canal and pipework, with confined interior stretches and exposed exterior stretches, without losing geometric continuity between the two.
Case study · Canal de Isabel II
3D laser scanning of the Santillana Canal.
More than 12 km of drinking water conduits on the Santillana Canal, in Colmenar Viejo (Madrid), scanned with a Leica BLK360 for Canal de Isabel II, the regional water utility of Madrid: the interior canal stretch and the exterior pipe run, in a single continuous 3D base.
A Canal de Isabel II asset in Colmenar Viejo.
The Santillana Canal supplies drinking water to part of the Madrid region. It is a long, narrow asset where everything depends on continuity: alignment, sections, gradients and ancillary elements have to fit together from end to end. Measuring it by hand, point by point, leaves gaps; scanning it in 3D captures the whole thing continuously, across stretches that run enclosed (with water flowing) and stretches of pipe in the open.
Work carried out
3D laser scanning with a Leica BLK360 inside the canal and along the exterior pipe route, with survey control to georeference the whole.
Result
A continuous point cloud of the entire alignment, ready for inspection, maintenance and technical documentation at Canal de Isabel II.
A technical base for Canal de Isabel II.
From the capture we produced the deliverables the utility's technical team needs to work against the real state of the canal.
Asset data
- Continuous point cloud of the interior canal and the exterior pipework.
- Documentation of the alignment, sections and relevant elements.
- A base for drawings, measurements or GIS/BIM integration.
What the client gets from it
- Remote review of the existing state of the canal.
- Less uncertainty before intervening in confined stretches.
- Better coordination between the utility's technical teams.
- A digital archive of the asset for future maintenance phases.
Technology used on this case.
Depending on scope, this kind of project combines terrestrial capture, drone, survey control, point cloud, GIS and web visualisation.
