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: 2.0 ± 0.5cm per pixel
- Front-Overlap: min 75%
- Side Overlap: min 70%
- 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.
If you would like to take advantage of our digital thread feature for object fusing you will need a very high absolute accuracy for each inspection that can only be achieved with the use of GCPs or a combination of PPK/RTK and GCPs. For more information on how to achieve this level of accuracy we have a support article to help here.

Blocks cannot be used for this data product, since one homogeneous output has to be produced
