Capture of Land Terriers for Local Authority Estates Department

Nov. 2016

We were approached by a client to digitise their paper-based legacy Land Terrier records, allowing them to proceed with the current and future records with a spatial element within the Uniform Estates system.

The paper-based deeds, in some cases going back over 100 years, had already been scanned and supplied in a PDF form but without usable positional information.  We were tasked with digitising the deed terriers marked on the scans, to cross check and identify anomalies with the current Land Registry data and raise any clear discrepancies between the entries.

All records were databased and included the following basic information:

  • Feature ID
  • Deed Number
  • Land Registry Reference where possible
  • Scan Sheet Reference
  • Anomaly Reference
  • Anomaly Details
  • Anomaly Action

The database information supplied was only limited by the clients requirements.  Normally we would utilise LLPG/AddressBase UPRN information during the terrier creation process.

All the land terriers were digitised as Polygons, with queries shown as Point or Line entries. Within the database all anomalies were given unique reference numbers with details describing the query and a notation for the action taken. These anomalies would then allow the council to query the land terrier with their legal department, and to investigate with Land Registry if required.  Any queries which could not be processed, were clearly identified with screenshots, scan sheet identifiers and provided as additional documentation, therefore all errors/queries were identified.  This included circumstances where Deed numbers were not legible, land terriers were shown without a Deed number, etc.

The generated files were then issued for testing as single and multi-part polygons in ESRI SHP format with the attribute data in Microsoft Access.  Of course we could have supplied the data in a variety of data formats according to the client's needs.

Throughout the process we captured the information into SQL Server using AutoCAD Map 3D.  The client was able to check project progress at any time by logging into our password protected Eye-TERRIER project site based on MapGuide.

From here the customer could view:

  • Polygons captured
  • Anomalies (points and lines)
  • Database information
  • Miscellaneous statistics such as
    • number of polygons captured 
    • % of area captured
    • Number of anomalies
