Land Registry s Digital Mapping Project A Driver for Change Dr Paddy Prendergast FIS Department of Spatial Information Sciences Dublin Institute of Technology, IRELAND An Opportunity for Change Existing Land Registry data model for mapping and folio information designed in 1890 s Irish Institution of Surveyors seminar in 1998 identified some procedures causing difficulty but Land Registry were not receptive to change at that time Digital Mapping Project is acting as a driver initiating change and beginning to shift attitudes in Land Registry towards accepting change 1
Protecting the Investment PRIVATE SURVEYORS Reform of of surveying procedures LAND REGISTRY Reform of of mapping procedures Reform of of Quality Assurance Procedures ~ 12 M Digital Cadastral Database (DCDB) Use of current procedures will quickly degrade new DCDB Improve quality of data input to incrementally improve DCDB Risk Management Paper Based Cadastre Digital Cadastral Database Increased risk due to more transparent nature of DCDB Need to employ risk minimisation / distribution techniques 2
Public Private Partnership PRIVATE SURVEYORS LAND REGISTRY Government policy encourages PPPs Dept. of Finance, 2001 European PPP model is to appoint publicly authorised surveyors under licence to act as Agents of the State DCDB Quality Improvement Stage 3 adopting improved ITM coords into DCDB Stage 4 -? Stage 5 -? Stage 2 - difference between cadastral boundary and orthophoto 3
Risk Distribution Licensed geodetic surveyor surveys property using agreed methodology to a defined standard using NRTK ITM coordinates produced are better quality than digitised coordinates in DCDB Licensed geodetic surveyor certifies (personal) new coordinates Land Registry acceptance of new information and update of DCDB transfers risk associated with this boundary information to licensed geodetic surveyors professional indemnity insurance Benefits of PPP Approach LICENSED GEODETIC SURVEYORS Clarity on standards for boundary surveys No fitting new survey data to DCDB information Better information on boundary features More professional service for clients LAND REGISTRY Process to rectify inaccuracies in DCDB Incrementally improve information quality in DCDB at no extra cost to State No duplication of data input to DCDB Distribute risk to licensed surveyors PII 4
Scenario 1 Which is the legal boundary in new DCDB? Land Registry s digitised property boundary (red line) Ordnance Survey topographic feature (black line) Scale off OS detail similar to current situation Multiple alternative solutions possible for each scenario Need to examine each alternative to identify best theoretical solution but also practical Publish guidelines and all (LR, OSi and licensed surveyors) apply the same solutions Scenario 2 Take ITM coordinates from DCDB and set out on ground, but these DCDB coordinates encroach into adjacent property, so which is correct? DCDB coordinates are the current legal position, so move boundary on ground to fit them? Boundaries on the ground have not changed for years (> 12 years), so coordinates registered are incorrect, and need to be updated? New procedure required to permit survey of new coordinates, get both adjacent property owners to accept them, and replace coordinates in DCDB 5
Panel for Boundary Issues LR IIS SCS OSi Mortgagers Law Society Panel needed to prepare now Predict what problems might arise with operation of DCDB and develop solutions Publish concrete guidelines to resolve particular problems Use Counties as they come on-line to test and refine solutions Dynamically address more and more boundary problems Summary Digital Mapping Project represents a golden opportunity to build a DCDB for future Time is short - DCDB goes live in early 2006 - need to prepare quickly - urgently establish panel to recommend best solutions for future Land Registry should examine the potential offered by a Public Private Partnership with professional geodetic surveyors Challenge to build capacity of personnel in Land Registry and geodetic surveyors to get licences 6
