The flowchart below shows the process followed whenever a real-world object represented as an OS MasterMap area
feature appears, changes or is removed from the landscape. The rules are described in more detail in the following

Creation of area features due to real-world change
When a new real-world object represented as an area feature – such as a pond, a building or a land parcel – comes

of OS MasterMap data will be informed of new features in their holding via change-only data update.
