A collection is a task used to define a permanent group of features to be used as a source of input data or calculation base in other tasks.
When several tasks (for example, ground surface tasks of the existing situation and different subsurface tasks) are used as indata to other tasks, it is smart to combine these in a collection task. The collection can be used as indata or calculation base in multiple tasks.
If there are changes in the indata tasks of the collection (for example, there has been a renewed ground surface due to new survey), the collection task is automatically updated and you need only recalculate the proceeding tasks that have the collection task as indata.
