Multi-project upload

Requirements:
Before initiating a multi-project upload, ensure your selected files meet the following criteria:
- RTK Data Only: Multi-upload is supported exclusively for projects containing RTK data.
- Same Processing Settings: Multi-project upload is not supported if the selected projects have different:
- Processing options
- Coordinate Reference Systems (CRS)
- Target upload locations
- No GCPs and Marks: Projects containing manually added Ground Control Points (GCPs) or Marks are not supported for multi-project uploading.

Project Re-upload
You can upload a project multiple times using different processing configurations without overwriting or deleting previous processing results in PIX4Dcloud. Each upload creates an independent processing version, allowing you to compare results generated with different settings.
How to Re-upload the PIX4Dcatch Project

Note: In PIX4Dcatch, projects can be uploaded in the background, allowing you to continue capturing a new project without waiting for the current upload to finish. Uploads continue even if you close the app, provided your device allows background activity and has an internet connection.
You will receive a notification on your device when an upload completes successfully or if an error occurs during the upload, keeping you informed of the upload status.
