Rural Payments Agency usage of Ordnance Survey data
- 1. Rural Payments Agency (RPA) usage of Ordnance Survey data Rupert Waite – RPA Geographic Information Services Peat Allan – Ordnance Survey
- 5. Change Intelligence - Re-active versus Pro-active Inspection (Physical, Remote Sensed) Customer (RLE1) Scheme (Lit/RD/FC) RLR MasterMap (one-off data refresh) MasterMap (Change Only Update) Points of interest data Aerial Photography (imagery analysis) Systematic “Pro-active” Updating BAU “Re-active” Updating Remote Sensing (imagery analysis on non-controlled)
- 6. RPA’s Route-map for Proactive Land Change Detection. Geo-Processes Routine/Cyclical Data Quality checks Pro-active Detection Improved Controls More current & accurate GI Source Data Requirement Engage with data suppliers, OS and Defra over currency Enhanced Tools System development & software Implement Data exchange to and from OS Action Outcome New business Processes Improved RLR accuracy Accurate SPS payments COU processes for Mastermap & Aerial Photography Improved MI on compliance Work Stream 1 Work Stream 2 Work Stream 3
- 7. Conceptual Design – Systematic “Proactive” Updating Sources of information Mastermap COU RPA collected data RLR Update Multi-step process to apply COU, to thematic dynamic thematic layers. Geo Information Data Integration – Geo processes Points of Interest data Aerial Photography COU Remote Sensing
- 9. What kind of OS Mastermap change will RPA see through COU? Current RLR The application of this change to the RLR would result in a reduction in field size from 3.11ha to 2.71ha for the field SP0653 0973 NB: This field has been claimed this year at 2.81ha New building and fence added 18/06/2008 RLR & COU

Notas do Editor
- OS MasterMap is a database in that each feature is captured as a record in the data, and is given a unique identifier known as a TOID ® . This means that any feature is easily and consistently accessed and identified, making any changes to the data easier to apply. It also means the TOID can be used as a link (or key) to other data – for example, Ineligible features for SPS. With these unique identifiers (database keys), the data is ‘database ready’ – that is, can be loaded into a database system. That, in turn, means the data can be stored once in an enterprise’s information systems and shared by many applications in the organisation – eliminating the problems that would otherwise exist in ensuring data is uniformly consistent.
- Photogrammetry is the science of measuring objects from photographs
