> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < CONTENTS Project overview Phase 1 Phase 2 Phase 3 Technical overview and progress Timescales for completion of Phase 1 Next stages – Phases 2 & 3

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < OVERVIEW: PHASE 1 Identify all known sources of marine infrastructure Determine the desired common CRS Identify inconsistencies in data Create infrastructure database and mapping Metadata assessment Determine rules governing feature deconfliction Identify base reference attributes Conduct feature deconfliction for pilot site OUTPUT => Phase 1 report and pilot area sample data MEDIN review

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < OVERVIEW: PHASE 2 Future expected programme of work: New data upload Attribute mappings Metadata creation Deconfliction of data Quality check of outputs Deliver output database of all feature types Phase 2 review of outputs OUTPUT => One definitive marine infrastructure dataset sourced from multiple suppliers, with best available geometry and attributes

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < OVERVIEW: PHASE 3 Review of project outputs for Phase 2 by nominated MEDIN representatives Agree Responsible Authority / Delegated Responsible Authority Establish long term data management and maintenance strategy method and frequency of update data delivery and formats ratify various requirements of IPR holders in licensing data Develop delivery mechanism of harmonised data to MEDIN and other 3 rd party parties Publicise!

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < PHASE 1 PROGRESS Identify and assess all known sources of marine infrastructure Common Data Access Ltd (UKDEAL) / UKHO / S-57 Pipelines / surface and subsurface infrastructure / wells Currency / attributes / coverage / scale / geometry / precision Dataset IPR assessment Unknown in some cases Determine the output CRS Geodetic WGS 1984 Identify inconsistencies in data Geometry Attributes

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < PHASE 1 PROGRESS cont. Metadata assessment Gaps in metadata Formats Standards – MEDIN profile Create infrastructure database, conceptual mapping, tools DB table structure (Oracle) Plug-in tools – upload / dictionary / mapping Conceptual mapping Identify base reference attributes e.g. Installation => Category of Installation Determine rules governing feature deconfliction Best available geometries Best available attributes For each dataset

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < PHASE 1 PROGRESS cont. Data processing CRS transformation Topologise data (links, nodes and seeds) Add, re-populate and cleanse attributes Import data to database (Oracle) Attribute mappings Using SeaZone developed tools Mapping of all features, attributes and attribute values into central data dictionary

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < PHASE 1 PROGRESS (pilot site) Deconfliction of features – pilot site Removes all duplicate feature types SeaZone developed plug-in tools Topologised data (links, nodes and seeds) Deconflict Seeds - Keeps only the best available feature Merge Seeds - Merges attributes onto preferred geometry

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < Deconfliction of features (using Deconflict Seeds tool) BEFORE: Duplicate pipeline features from different sources Deconflict AFTER: Single best available geometry for pipeline feature Land area

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < Deconfliction of features and attribution harmonisation (using Merge Seeds tool) BEFORE: Duplicate pipeline features from different sources with varying attributes Merge AFTER: Single best available geometry with best available attributes Feature attribute harmonisation

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < PHASE 1: Following completion of pilot site deconfliction: Quality checking of outputs Geometries Attributes Metadata Deliver output database of GIS feature types ESRI v9.1 PGD format Supporting metadata and statistics

> BETTER DATA, BETTER SCIENCE, IMPROVED DECISIONS < NEXT STAGES Timescales: Deconfliction of pilot area Completion – by mid September 2010 Project report and pilot site data sample Distributed – before end September 2010 Project partners review Phase 1 outputs Mid September – Beginning October 2010 Project Partners review meeting – beginning of Oct 2010 Agreement on costs and timescales for Phase 2 Agree expected programme of work for Phase 2
