Drone Mapping Tips & Tricks

Natural ground control points increase drone mapping accuracy

Accurate mapping is the cornerstone of numerous fields, from urban planning and environmental management to disaster response and infrastructure development. At the heart of achieving precision in mapping lies the strategic placement of ground control points (GCPs), which serve as reference markers for aligning aerial (including drone) or satellite imagery with real-world coordinates. While traditional

How to share insights from drone mapping data

As humans we like to simplify reality. To take complex systems or ideas and break them down into digestible, communicable chunks. It’s why we classify the Earth as ‘land’ and ‘water’. But the Earth is infinitely complex, as is the drone data that we capture about it. So how can we decomplicate things and make
