Plotting and Scaling
It is the responsibility of the plans settler to map the cadastral unit onto the cadastral map using the latest available Ordnance Map (OS) base map. The extent to be registered will be based on the information submitted with the application for registration.
When the boundaries of the plot shown on the deed plan (or described in the full bounding description) in the application for registration agree with the map features shown on the OS map, then these map features will be followed by the plans settler - see Further Guidance on Vector perfect Mapping.
When the boundaries of the plot shown on the deed plan (or described in the full bounding description) in the application for registration do not agree with the map features on the OS map, or no such features are shown on the current version of the OS map, then the plans settler is responsible for accurately transferring the detail from the deed plan to the cadastral map. This process is known as plotting and scaling.
There are various tools and resources available to the plans settlers to help them transfer detail from a deed plan onto the cadastral map.
1 Core Mapping Skills modules
Within PAL, plans settlers can access modules that specifically cover the key elements of plotting and scaling. These modules can be revisited at any time to support settlers in their day-to-day job:
Scale & measure
Framework of control
Map polygons on the Plan Creator
2 Training booklet
Although this booklet was created some years ago when the DMS was the main mapping tool, the basic principles of plotting and scaling remain the same.
3 Plan Creator Georeferencer
In certain circumstances, the Georeferencer within Plan Creator can be used to help transfer detail from deed plans to the cadastral map. See the Georeferencer Guidance section for information on how and when to use this mapping tool.
