Divide Region
Function Description
Divide Region divides the Split Data in the Split Data set area, and assigns the attributes specified by Split Data to the split face objects in the Split Data area.
Application scenario
It Is used to change the Land Use type. For example, ten years ago, the Land Use type was paddy field. Ten years later, for some reason, half of the paddy field area becomes dry land. At present, the paddy field of ten years ago can be divided through the Divide Region function as long as the Region Dataset of dry land is available. It is divided into paddy field and dry land, and the attribute of dry land is assigned to the partitioned paddy field in the partition area.
