Digital data

This guidance contains information about using digital data in your registration application, including mapping, formats and labelling.

Submitting digital data

Please note that the digital data must accurately represent the legal position of the title to be registered.

Where a voluntary registration application is being submitted which uses digital data as an alternative to paper based plans the application must include a .pdf to assist with the mapping of the subjects. Under these circumstances, failure to provide the .pdf will result in rejection of the application.

Where an application uses paper based plans / deeds to define the extent, but digital data is also being submitted, it would be beneficial if a .pdf of the layout is also submitted to use as a visual representation. However, failure to provide a .pdf under such circumstances will not result in the application being rejected.

Where digital data is being submitted as part of an application, it should be sent by email to digital.data@ros.gov.uk. It should be noted in the further information section of the application form that digital data is being submitted by email, and the file reference should be provided.

Base mapping

Registers of Scotland (RoS) use Ordnance Survey (OS) MasterMap topography layer to produce the cadastral map.

About the cadastral map
The cadastral map shows the registered rights, title and interests in land for Scotland.

The layer is the Ordnance Survey's most detailed, current and comprehensive map dataset of Great Britain. All data must be created from this layer whether the data is digitised from paper maps or supplied directly from computer aided design (CAD) or geographical information systems (GIS).

It is essential that data supplied to RoS is created using OS MasterMap topography layer as its basis. In the case of boundaries which are not defined on OS MasterMap, the boundary must be digitised relative to any surrounding OS features. Use of other maps will result in misaligned data and provide insufficient detail to identify boundaries.

Data formats

  • GIS data should be supplied to RoS using the following essential criteria.
  • The preferred option for all spatial data is Esri shape file format. When submitting shape file data, the following files must be included: *.prj, *.dbf, *.shp, *.shx.
  • All data must be spatially referenced and projected to the correct datum and projection. All shape files must be submitted with a .prj file defining this projection and coordinate system. The correct datum and projection to use are cited below (http://epsg.io/27700).
  • Datum: OSGB1936
    Projection: OSGB 1936 / British National Grid
    Geodetic CRS: OSGB 1936
    Ellipsoid: Airy 1830
    Prime meridian: Greenwich
  • All spatial data must be topologically correct (no gaps or overlaps).
  • The shape file must be of polygon geometry type and consist of one or more polygon features.
  • The shape file attribute table (.dbf) should individually identify and correspond to the deed plan.
  • The shape file must contain a single entry in the .dbf for each polygon. No multipart features will be accepted.
  • The data should be created using Ordnance Survey MasterMap topography layer as your base map. While it is not necessary to submit a separate feature or shape file depicting your base map it can be very useful to RoS in resolving temporal base map conflicts.
  • Other data formats can only be accepted if the criteria listed above can be confirmed.

Data description/labelling

All data submitted to RoS must include the following information. There are no specific file-naming standards, however, the file name should be descriptive in terms of site name or site location.

Delivery date: the date the data is delivered to RoS

Revision date: the date of revision (where applicable)

Subsequent delivery date: date of delivery after revisions

Reference number: the RoS reference number: cadastral number, application number or report number are all acceptable.

Summary: a summary of the contents of the data

Software version: the name and version of the software used to create the data

Contact: submitting organisation or individual names and contact information

File information: list of files submitted

Delivery date: 26/06/2015
Revision date: 27/06/2015
