4 Keys to Good Maps & Models
Photogrammetry – the art and science of taking measurements from pictures – is an essential part of a wide variety of enterprise drone operations. Whether you’re modeling cell phone towers, monitoring progress on a construction site, or inspecting large solar arrays for potential efficiency loss or fire hazards, being able to use drone imagery to create 2D and 3D representations of reality has wide-ranging benefits. But, sophisticated as the technology is, the end product is largely dependent on properly captured data and a well educated pilot.
In this guide, we’ll share four best practices for Drone Photogrammetry:
- Why pixel size matters and what impact Ground Sample Distance has on the quality of data captured
- What role overlap plays in producing a better quality image
- What elements to consider to ensure the target area is rendered accurately
- How Ground Control Points contribute to high absolute accuracy
