Our geospatial team is available whether you’re on site, in the office, or remote. Choose from over 5,000 published coordinate reference systems, or upload your own.

High-precision LiDAR made simple

Propeller makes LiDAR practical for your work site. Capture true ground conditions before clearing or earthwork, then offload processing, QA/QC, and classification to Propeller. Get ready-to-use terrain models, point clouds, and orthomosaic that fit seamlessly with your photogrammetry data.

With Propeller LiDAR you can

Quickly process complex LiDAR datasets without specialized software
Penetrate vegetation to capture true ground conditions
Integrate LiDAR outputs with photogrammetry for a complete site view
Work at any site size and in any local coordinate reference system

“I think the datasets speak for themselves. It’s nothing that you have to bring anyone onboard with. It’s data that’s intrinsically and obviously valuable.”

– Matt Eklund, GPS Program Manager at Sukut

FAQs

PPK drone mapping is a post-processing kinematic workflow that improves the accuracy of drone surveys by combining aerial imagery with precise ground control.

Unlike real-time kinematics (RTK), PPK performs corrections after the flight, making it more reliable and accurate, especially for large or complex sites.

Use recommended drones with AeroPoints, follow the PPK workflow, and validate your data with Propeller’s geospatial data processing.

PPK drone surveying captures images with precise GPS data from AeroPoints and the drone, then applies post-processing kinematic corrections to produce survey-grade 3D maps.

PPK ensures precise, repeatable results for planning, reporting, and compliance, even on sites with vegetation, rough terrain, or complex features.

Using Propeller’s PPK workflow and recommended equipment, surveys can reach 1/10ft (3cm) accuracy.

RTK-enabled drones and AeroPoints are required for full PPK integration and high-precision survey results.
