We create accurate and highly detailed models efficiently with terrestrial laser scanning of the target area’s current situation. We also collect data with the help of a backpack-mounted laser scanner and other mobile platforms. Read more about Mobile Mapping.

A laser scanner will always produce a point cloud from which a 3D-model can be created should such be required. Both the point cloud and the 3D-model are georeferenced and to scale, making it possible to collect accurate measurements from within them. Point clouds are well suited to visualization and further processing, and can be delivered in LAS, PTS, or XYZ formats. The point clouds may contain intensity values or color values to create a more realistic visualization, if desired.

The point cloud is used to create a 3D-model, with the desired detail and BIM levels. This can be anything from large, rough constructions such as tunnel contours to small details like wall / façade decorations. Metadata can be attached to the digital objects, such as pipe type, manufacturer, feature code, post number, infrastructure type, and much, much more.

This makes the data very well suited for further processing in a BIM, CAD or GIS environment such as Revit, AutoCad or ArcGIS. Many modern tools provide the possibility of working with the information within this type of 3D-models, as well as using point clouds for visualization.

A 3D-model like this is often an invaluable tool when adapting new projects to an existing area. The architects get to work on an accurate Revit-model, thus allowing new solutions to seamlessly integrate into the old.

Terrestrial laser scanning has a higher accuracy than mobile laser scanning, and is used when there’s a need for higher accuracy and point density. Terrestrial laser scanning can also be combined with other measuring methods where necessary; for example with drone data, land measurement data, or data from the Pegausus:Backpack.

Scan Survey uses both a Leica P50 and a P20 laser scanners both of which send and receive up to one million points a second. This gives a three-dimensional representation of everything the laser hits, allowing for immense data collection over a short time period. Scan Survey has extensive experience with terrestrial laser scanning.

We have helped architects in scanning large buildings and industrial sites, universities, tight attics, and the facades of listed buildings. Designers have received models of long tunnels, large train stations, quays, city streets, dark culverts, and old irrigated hydroelectric plants.

We have performed geometric controls of long piles, as well as those of large concrete tunnels, rough buildings, and bridges on behalf of construction clients. Landscape architects have received our help with the visualization and measurement of parks and forests to ensure that new interventions merge perfectly with the vegetation.
