Ground Control Points (GCPs) can be included in a PIX4Dcatch project to reach cm-grade absolute accuracy. With GCPs in the area of the scan, processing with PIX4Dmatic, PIX4Dmapper, or PIX4Dcloud Advanced allows for the inclusion of those GCPs.
There are 3 ways to include GCPs in a PIX4Dcatch project.

Include GCPs using PIX4Dmatic
- Export the project files from PIX4Dcatch. How to export PIX4Dcatch projects (iOS/Android) for more information.
- Create a New Project in PIX4Dmatic with the data.
- Import and mark the GCPs. Refer to Tie Points (GCPs, MTPs, and CPs) - PIX4Dmatic for more information.
- Process locally in PIX4Dmatic and eventually upload the results to PIX4Dsurvey or PIX4Dcloud, if needed. How to import a PIX4Dmatic project into PIX4Dsurvey, or How to upload or replace results to PIX4Dcloud for more information.
Include GCPs using PIX4Dmapper
- Export the images from PIX4Dcatch. How to export PIX4Dcatch projects (iOS/Android) for more information.
- Create a New project in PIX4Dmapper importing the images taken with PIX4Dcatch.
- Import and mark the GCPs: How to import and mark ground control points (GCPs).
- Process locally in PIX4Dmapper and eventually upload the results to PIX4Dcloud, if needed. Alternatively, upload the project files for processing on PIX4Dcloud.
Include GCPs using PIX4Dcloud Advanced
This method can only be used if some requirements are met. Please, consult the full requirements list here.
- Export the images from PIX4Dcatch. How to export PIX4Dcatch projects (iOS/Android) for more information.
- Create a New dataset on PIX4Dcloud importing the images taken with PIX4Dcatch.
- Follow the guided procedure to include the GCPs. For more information: AutoGCPs detection functionality.
