Our goal is to process your data as quickly and efficiently as possible to ensure customer delight. We invest a significant amount of time and effort to process it successfully the first time, however, capturing these thousands of images can be tricky and we understand that. Therefore, we created the following guidelines that apply to both your flight and as-built plans to ensure your data is uploaded in a manner that allows us to extract the needed results. We promise these best practices will save you a lot of time and frustration.
Drone-Captured Visual (RGB) Image Requirements
- GSD: up to 1.0 cm per pixel
- Front-Overlap: min 70% (increase if terrain/building is complex)
- Side Overlap: min 60% (increase if terrain/building is complex)
- Flight Path: At least 2 flight lines should be outside the boundaries of the operation in all directions
- Gimbal Orientation: Nadir (-90 deg). Capture additional oblique photos for improved quality in case of complex terrains/buildings.
- Image Format: JPEG - Each image should contain the following metadata: GPS location, relative altitude and timestamp
- Image Quality: in focus, free from motion blur and with minimal glare
- At least 20 photos need to be uploaded
Ground Control Points (GCPs)
Ground control points are optional, but highly recommended. Even when using high-accuracy photos that have been geotagged using an RTK or PPK solution, we recommend placing at least one GCP for optimal accuracy.
