Mine surveying software built for the entire mine.

Propeller CAD supports preliminary earthworks concepts such as haul roads, ramps, and pads on real survey terrain. Use it to explore options before specialist review and detailed engineering. It is not a tool for production blast design, tailings-dam engineering, or geotechnical certification.⁠

Yes. Our Composite Builder lets you merge multiple smaller surveys into a single, comprehensive site map. This keeps your view of the mine up to date without needing to fly the entire site every time you want to track progress. You can read more here.

Yes. Propeller mobile puts the platform in your pocket. It gives field teams, superintendents, and foremen a reliable source of high-precision data right on the worksite. This allows them to track location and perform critical grade checks from the cab or the pit floor.

Yes. You can upload your own LiDAR point clouds or we can process and classify raw LiDAR scans for you. This is ideal for capturing existing ground through vegetation before clearing begins.

We believe in connecting your entire team. Because every site is different, we work with you to build a plan that fits your specific sensor, data, and usage needs. This ensures everyone from the office to the field has access to the same map. 

Propeller is designed to be intuitive, but we don’t leave you hanging. Our team of customer success engineers, GIS specialists, and hardware experts will set you up for success from day one.

We accept data from all major drones, sensors, and GPS systems. While we are hardware agnostic, we can also recommend specific drones that fit your accuracy and workflow requirements.

Absolutely. You can manage access using our people and teams structure. This allows you to limit permissions for contractors or external stakeholders while giving your internal team full access.

Yes. Propeller is not a data silo. You can download data in numerous file formats such as .DXF, .XML, or .TTM for seamless use in third party software like Vulcan, Deswik, or CAD.

Drones capture hundreds of millions of data points across a site in a single flight, compared to hundreds or low thousands from a ground crew. Combined with PPK or RTK positioning and ground control like AeroPoints, drone surveys deliver centimeter-level accuracy across entire pits — and they do it in hours instead of days, without putting surveyors near highwalls or active equipment.

Traditional GNSS surveying samples discrete points on the ground, then interpolates between them. A surveyor walks the site with a rover and records readings. Drone mine surveying captures the entire surface as a dense 3D model, so volumes, slopes, and changes are measured from continuous data instead of sampled points. The result is faster turnaround, far better stockpile and reconciliation accuracy, and the ability to inspect hazardous areas without sending people in.

Drones don’t replace formal geotechnical engineering review, but they remove the need to put crews next to high-risk faces for routine inspections. Propeller lets you capture vertical face imagery, monitor tailings storage facility fill rates with heat maps, and visualize slope angles and water accumulation remotely. The result is more frequent, auditable inspections with less personnel exposure.

Drone surveys give you precise pre-blast surface models for accurate blast volume estimates and drill pattern design. Post-blast, the same workflow measures muckpile shape, fragmentation, and material movement. Comparing pre- and post-blast surfaces closes the loop between blast design and actual outcome, which feeds better designs the next time around.
