Propeller

Propeller develops drone mapping and 3D site analytics software for construction, mining and earthworks teams. Founded in 2014 in Sydney, Australia, the company builds tools that allow site operators to map, measure and manage worksites using aerial imagery processed into survey-grade 3D models.

Its main product, the Propeller platform, is a cloud-based system that turns drone-captured imagery into 3D maps for real-time site measurement and management. According to the company, the platform powers more than 50,000 worksites across 120 countries. Alongside the software, Propeller supplies AeroPoints, smart ground control points used to achieve accuracy in drone surveying, and DirtMate, hardware for real-time machine guidance on earthworks and construction sites.

The company's technical work spans aerial imagery processing, cloud-based processing, survey-grade 3D mapping, real-time machine guidance and geospatial analytics. Its stated focus is on making survey workflows simpler and faster for people on the ground, and on challenging established practices in surveying and construction.
