Inventory is performed through photogrammetry (partly by air and partly by rail) and laser scanning. The collected information provides height models as well as 3D models of the track and its surroundings.
Our maintenance inspection provides, for example, distance measurements of assets along the track such as signs and vegetation. Every asset is assigned an ID number connected to an SQL database as well as a map.
The inspection provides a protocol for assets that may be potentially disruptive or dangerous to transport.
Our measurements provide information about assets such as banks, dikes, lines, wells, posts and fences for example. Tunnel contour measurements can provide information about mouths and ports, normal sections, deviant sections and reinforcements.
As everything is rendered in 3D, the client can decide which measurements they need to be delivered, for example perpendicular from the centre of the tracks or measurements of height, width or other specified coordinates.
Our photographic documentation of tunnels and mountain passes gives detailed information regarding the status of tracks and/or surroundings, such as reinforcements, frost isolations, views of passes and crests.
Besides charting, risk analysis can be performed regarding, for example, cracks, mud zones, water and vegetation in tunnels and on crests. We can also locate all dangerous trees along the track that could cause disruption to lines.
The presentation of data is clearly and quickly implemented in a dedicated 3D program DPM Inspection. Data from multiple sources are integrated in a single environment and thanks to obtained synergies, the information infrastructure is more complex and accessible.
The obtained data can also be used for:
