New layer in the web editor to display the GCPs
When a project is processed by using the AutoGCP functionality (after 10th February 2021), there will be a new layer in the editor containing the GCPs and Check Points.
They will be superimposed on the 2D and 3D views: GCPs in purple and Check Points in yellow.
This new layer helps to know how accurate your project is just by having a quick look at the GCPs and Check Points locations.
- When sharing the project, the GCP layer will also be visible.
- If the GCP detection fails and no points are found, the GCP layer will not be visible at all.
- If the GCP detection only finds a few points, the GCP layer will only contain those points.
Before using the GCP functionality, remember that:
- Only squared and diagonal targets are supported
- Targets should not be smaller than 5 times the average GSD of the project.
- Black and white targets are supported. Other colors may work in some circumstances.
- GCPs must be placed at a distance of at least 12 m from each other.
- GCPs must have a projected coordinate system whose definition is included at https://epsg.io.
