The document discusses the role of Ireland's National Mapping Agency (OSi) in maintaining national mapping infrastructure and providing location data. OSi collects mapping data through fieldwork and aircraft, manages large geospatial databases, and provides mapping products and services to government, businesses and citizens. It outlines OSi's plans to develop a new spatial database called Prime 2 to meet current and future demands for authoritative geospatial data.
OSi Local Gov User Group Presentation
- 1. An update from your National Mapping Agency Hugh Mangan Head of Marketing & Business Development
- 2. OSi’s Role in National Mapping Maintain and develop the underlying physical infrastructure of the State which is needed to support mapping applications. We create consistent and homogenous, maintained digital databases. We provide similar information across the entire country, which enables government, businesses and individuals, the ability to create policies, operations and expectations of a countrywide nature.
- 3. Location Matters to Government Important part of State infrastructure adding value to key national projects: Knowing where something is protects its value & makes possible the integration of data from different government departments for effective planning and decision making.
- 4. Location Matters to Citizens Q: Which of the following would have a negative impact when making decisions about where to live? % Potential for Flooding 69 High levels of traffic 66 Unfinished housing or ghost 62 estates nearby Industrial sites 62 Lack of amenities 59 Poor transport links 57 High rise buildings in close proximity 55 Poor shopping provisions 52 Hazards (e.g. rivers etc.) 50 (Base: All Adults 16+ – 500)
- 5. How does our data add value to you? Location as the common link • Better Planning: Water, Sewage, Planning Applications, Roads, Housing, Heritage, Engineering works etc. • Better Citizen Services: Powerful tool for demonstrating and analysing the physical evidence of issues. • Better Resource Optimisation: common referencing framework for all. • Better Decisions: Rapid access to up-to- date information across organisation & public. •Slide 5

- 19. Archaeology - Hill of Ward “Birthplace” of Halloween • Research by Dr Steve Davis UCD • Despite the presence of an important 'royal' site at the hill's summit, the known archaeology of the area immediately surrounding the hill is sparse. Only two extra sites have been previously recorded • It was anticipated that analysis of LiDAR coverage from the area might bring to light previously unidentified low- profile archaeological features and so enhance the archaeological understanding of landscape in the vicinity of the hill itself. – More archaeology then previously thought. – Previous interpretations of the site itself are both corroborated and questioned

- 22. What next from OSi?
- 23. The industry is changing …. fast Practically overnight, access to terabytes of geographical information, much of it in three dimensions, has changed the way people work, live and entertain themselves. Paper Digital PC /Server Web Any Device
- 24. Industry Change New services, leading to millions of users. GIS GIS App Global Researcher Professional User Users DIY with Serviced Desktop / Web Cloud Solution New Raw Data Solution Server Services SasS Audiences Serviced Solutions New New New applications, Requirements Software delivered in new ways Changing Industry New New Data Skills IT, Web, Mobile Open & Interoperable Data Development Skills Open & Raw GIS Ready GIS + Interoperable GIS + Data Data GIS Software Data Business Development
- 25. Prime 2 A new spatial database to meet current and future demands • Industry standard spatial data storage model that allows digital spatial information to be stored and managed effectively in relation to the OSi authoritative digital reference mapping. • A database of real world features derived initially from multiple current sources. • Seamless, scale independent, object based spatial data management infrastructure. • The most significant revision to OSi’s data management and product generation process in over 30 years. • Completed and available by June 2013.
- 26. Why? Industry Requirement for.. • Open and Robust Data Model – To be used across a variety of systems Rigorously based on • Consistency industry standards: – Logical, Thematic, Temporal, Attribution • Data model > OGC Simple Feature Model • Integrated • Metadata > ISO 19115 – Coping with many types of spatial data • Roads > GDF standard • 3D > ISO CityGML Level • Representative 2 – Models the world in a more intuitive • Supply > GML data & and logical way OGC compliant web services
- 27. Prime 2 Enables… • Link objects using persistent ID (GUIDs) • Use Form and Function classifications • Build Relationships buildings / way • A metadata rich storage model from which a multitude of products can be automatically generated. • Full networks connectivity (roads, water) – Road centre line GDF1 & GDF2 – Distinguish road surface, paved areas, grass verges • New supply possibilities – Develop schemas to suit your needs • Manage change only data
- 29. Benefits • Achieve higher data quality levels • Implement new products and services • Allow for more effectively management of data • Metadata is captured not only at the dataset level or the individual object level, but down to the individual attribute level. • Allows the user to “graft” their own data on to the new model • Meeting the challenge of “Shared Services” – Water Charges – Household Charges – Septic Tanks – Lighting
- 30. MapGenie Overview • Award winning web based mapping services that allow users to connect directly to OSi’s national map database online • Data can be used in standard Geographical Information System (GIS) software, or it can be used in web or mobile applications. • Standards based with open format • Designed to deliver rapid, easy access to map data and aerial imagery
- 32. New Services • Buildings Polygons – with GeoDir address points, and DSM, DTM height data • GeoDirectory Points Service • GeoDirectory Address Service • National Gazetteer Address Service • Grayscale Basemaps • Discovery Service • 25cms Ortho Cities • 25 cms Ortho Towns • Pre-publication 1m res Orthos • Irish Language Service
- 33. How we identify change
- 34. Model for future? OSi acts as a trusted custodian for spatial data, stores it centrally and serves it back to Local Authorities or centralised Local Authority applications. •Slide 34
- 35. Where to next for OSi?
- 36. Public Sector Reform • Merger Process on-going • Working Group Report June 2012 • Cabinet decision thereafter
- 37. What can OSi do - Reduce, Move, Create 1. Continue to reduce our operating costs so we can reduce licence costs 2. Move as many services and deliveries online – so we increase efficiencies 3. Move up the GI value chain (enhanced web services) 4. Create the environment within which the benefits of authoritative, maintained and consistent spatial asset is fully recognised.
- 38. OSi manages national coverage large-scale topographic data, which is a national asset and resource delivering value for money to the State, private enterprise and citizens.
Editor's Notes
- #3: So what?Maintain & develop the underlying physical infrastructure which is needed to support mapping applications.Technical support to the Chief Boundary Surveyor in performance of his or her duties in delimiting statutory boundaries.Provision of national geodetic infrastructure to enable standardised positioning (Mapping / Height / Measure).Provision of authoritative Geographic Information (GI) reference data.Participation in national programmes (INSPIRE / EPA Land Cover group).Developing a geographic information framework to enable the integration of public sector spatial information (Prime 2).
- #4: So What?Location affects every part of our lives, OSi are the State body ensuring the value of location to made available to citizens and government alike.
- #6: So What?Can you see the value that is provided by OSi dataFingal “permeable distance calculation”vs “straight line distance”Transport – wont send a full bin lorry up a steep inclineMobile workers – collection more accurate data in the field.
- #10: Nearly all Local Authority services are tied to a location.Water ServicesEnvironmental ServicesWaste ServicesFire ServicesHousing PlanningRoadsHeritageRates
- #27: Background to this initiative
- #29: Click on a road segment (the “Way Area” layer) – it highlights on the map and a pop-up appears on the map listing the attributes associated with that road segment. At the bottom of the pop-up are links to related data – in this case, the highlighted road segment has related Building Points and Building Areas
