A DroneMetrex executive says data capture with the company’s TopoDrone-100 for the railway mapping project took only two hours and the data met all the client’s requirements.

DroneMetrex announced it successfully performed a high-precision railway mapping project in Australia with its TopoDrone 100 unmanned aircraft system.

The mapping project was aimed, in the first instance, at creating a 3-D “real world” for obscurity analysis when approaching an intersection from a train driver’s perspective as well as from a vehicle driver’s perspective. Second, highly accurate mapping was performed for future civil works involving repair as well as upgrading of the existing railway.

Traditionally such projects presuppose aerial photography, LiDAR and corridor mapping from large manned aircrafts, which wasn’t economically justified in this particular case because of the project area’s small size. At the same time, conventional ground surveying techniques weren’t applicable, as they would require the railway to temporarily close to observe all health and safety standards.
