A dataset can be divided into subprojects either automatically using the Split into Subprojects option or manually.
In order to split a project into subprojects:
1. Click Project > Split into Subprojects...
2. (optional) On the Split the Project into Subprojects pop-up, change the Maximum Number of Images to the desired value and/or the Suffix of the Subproject's Name. For more information about the setting options: Menu Project.
3. Click OK.
One-flight Areal Project
Estimate the distance between the flight lines. It is recommended to divide the dataset in flight lines that have the smallest distance between them, so as to maximize the overlap between the subprojects.
Several-flight Aerial Project
Fly the different flights so that there is common area covered by as many flights as possible. Each flight can be one subproject.
Split the project into subprojects in such a way so that different subprojects share common images. This will ensure that there is overlap between the subprojects, which will facilitate merging.
