Drone Survey Requirements
To generate an accurate high-resolution orthophoto, a minimum of 75% front overlap and 65% side overlap is recommended. This ensures that the Structure from Motion algorithms have enough common tie points between disparate photos to reconstruct the camera graph.
Pro Tip for Map Accuracy
Always capture nadir (camera pointing straight down 90 degrees) images for standard maps, but include oblique images at 70-80 degrees if you intend to generate a 3D Mesh or Point Cloud. The side profiles help reconstruct buildings correctly.
Next Steps
Once you have your dataset, zip your JPEGs and upload them directly to our secure upload portal. Our A100 GPU cluster will process the files automatically.
