The digitization of railway infrastructure is reaching new heights. While traditional mapping accurately documents the geometric state of tracks, integrating multispectral data opens up unprecedented possibilities for preventive maintenance. At the heart of this evolution, combining visual and thermal orthophotos stands out as a major driver for operational efficiency.
Merging the Visible and the Invisible
On a railway infrastructure, many assets essential to traffic regularity are difficult to monitor with the naked eye. This is particularly true for track switch heaters—critical systems designed to ensure smooth track operations during freezing periods.
By integrating thermal orthoimages into a digital workspace (Workspace), it becomes possible to make the invisible visible. The swipe tool allows users to overlay a standard orthophoto with a thermal orthophoto of the exact same area. With just a swipe of the mouse, technical teams can pinpoint the precise location of the heaters and verify their correct configuration on the ground.
Tracking History to Better Anticipate
Beyond instant inspection, the true value lies in temporal tracking. By comparing two thermal orthophotos captured at different dates on the same section of track, the swipe tool immediately highlights network evolutions.
This comparative analysis allows for the instant detection of:
- Unexpectedly deactivated track switch heaters.
- Faulty or underperforming equipment.
- Priority zones requiring technical intervention.
Having access to this visual and thermal history provides complete traceability of asset conditions. For infrastructure managers, it ensures a shift from reactive, forced maintenance to a mastered preventive strategy—guaranteeing network availability and safety all year round.
Securing Long-Term Infrastructure Through Chronological Tracking
Static digital twins are a thing of the past. The future of infrastructure maintenance relies on chronological, thermal, and dynamic tracking. By mastering the swipe tool in the Altametris Suite Workspace application, industrial players can secure the long-term viability of their infrastructure, protect field teams, and focus their maintenance efforts where operational efficiency and time savings are maximized.
