Processing images with different spectral signature (RGB, NIRGB, etc) in one project can be useful, for example, in the following cases:
- Generating different orthomosaics (one orthomosaic per dataset) that are perfectly overlaid because they are generated from the same DSM.
- When processing different types of imagery together, all input bands contribute with a specific weight to the keypoint extraction. Thus more 3D points can be extracted than when processing each dataset separately. This leads to a more precise DSM, in turn leading to better orthomosaics.

Band configuration - Grouped Images
Pix4Dmapper reads the EXIF data from the images in order to retrieve an EXIF ID that is used to associate each image to a camera model from Pix4Dmapper's database. The following cases can be encountered:
- Images with different EXIF ID detected with correct band information
- Images with different EXIF ID detected with incorrect band information
- Images with the same EXIF ID detected with incorrect band information
Images with different EXIF ID detected with correct band information
1. Create a new project. For step by step instructions about how to create a new project: Step 2. Creating a Project.
2. In the New Project Wizard, add all the images. Images with different EXIF ID that are associated to different camera models with the correct band information are already grouped correctly.
3. Process the project. For more information about how to process a project: Step 4. Processing.
Images with different EXIF ID detected with incorrect band information
1. In this case, in order to group the images correctly and to set the correct band configuration, follow: How to merge Images with different Spectral Signatures (RGB, NIRGB, etc).
