Historic Environment data – inherently spatial
But we don’t always know where the data is • Retained by the data creator• Lost• Deposited in an archive – if so which archive
o Is it accessioned?o Is it catalogued?
• Or how to use the data with other datasets o Lack of standards in contento Accuracy and format across projects
• Further hindered by accessibility o Copyright o Intellectual Property Rightso Data hoarding
….but not easily accessible
INSPIRE sets down the general rules for establishing an infrastructure for spatial information in Europe for the purposes of Community environmental policies and policies or activities which may have an impact on the environment
• Data should be collected once and maintained at the level where this can be done most effectively
• The ability to combine seamlessly spatial data from different sources and share it between many users and applications
• Spatial data should be collected at one level of government (the Profession) and shared between all levels
• Spatial data needed for good Governance should be available on conditions that are not restricting its extensive re-use • It should be easy to discover which spatial data is available, to evaluate its fitness for purpose, and to know which conditions apply for its use.

Annex I1. Coordinate reference systems2. Geographical grid systems3. Geographical names4. Administrative units5. Addresses6. Cadastral parcels7. Transport networks8. Hydrography9. Protected sites - *
Annex II1. Elevation2. Land cover3. Ortho-imagery4. Geology
Annex III 1. Statistical units 2. Buildings 3. Soil 4. Land use 5. Human health and safety 6. Utility and governmental services 7. Environmental monitoring facilities - * 8. Production and industrial facilities - * 9. Agricultural and aquaculture facilities - * 10. Population distribution – demography 11. Area management/restriction/regulation zones & reporting units - * 12. Natural risk zones 13. Atmospheric conditions - * 14. Meteorological geographical features - * 15. Oceanographic geographical features 16. Sea regions 17. Bio-geographical regions - * 18. Habitats and biotopes - * 19. Species distribution - * 20. Energy Resources - * 21. Mineral resources - *
-* heavy weighting towards the natural environment
Annex I Protected Sites and the wider Historic Environment
A Protected Site is defined as an
“Area designated or managed within a framework ofinternational, Community and Member States' legislation to achieve specific conservation objectives” [Directive 2007/2/EC].
“..a Protected Site is an area of land and/or sea especially dedicated to the protection and maintenance of biological diversity, and of natural and associated cultural resources, and managed through legal or other effectivemeans.” [International Union for the Conservation of Nature]
The INSPIRE Directive – Protected Sites

Social, Economic and Environmental Benefits
The INSPIRE Directive
• Requires that existing data held by member states is compliant with INSPIRE standards
• It does not require the creation of new datasets but it does state that when new datasets are created they must comply with INSPIRE standards
• INSPIRE requires Metadata for the creation and maintenance of searchable catalogues to identify what data is available, who holds it and any access constraints.
• INSPIRE requires data publishers to setup network servicesView Services (WMS) Transformation servicesData harmonisation – consistent schemaDownload services (WFS and ATOM feed)
• INSPIRE outlines charging for public access to services
• Monitoring and reporting on INSPIRE compliance
• INSPIRE is about Public Sector data – it does not address data created by the private sector
Publication in Portals
Compiled by data curatorPublished on Scottish SDI
Harvested to UK data.gov.uk portal
(and copied to MEDIN portal for marine data)
And in turn to the INSPIRE geo-portal
Separate metadata records for Resource discovery (datasets)View: Web Map Services Download: Web Feature Services
Data search and retrieval only as good as the Indexing of terms
What is needed is a dedicated portal for heritage datasets ?

There is a wealth of spatial data created through fieldwork, analysis and designation
The value of the data is not realised beyond the individual project- too often locked into publication and grey literature reports or catalogued in an archive
There is a need for a thematic approach to mapping: A Spatial Data infrastructure for Heritage
A thematic Spatial Data Infrastructure … work in progress?
Access Mechanism
Framework GI / Thematic GI
Component GI Services
Interoperability Standards CIDOC – CRM, Europeana EDM
Portals, Metadata, View and Download services
Need to agree on datasets and specifications
Policies / Legal Framework INSPIRE but no sectorial framework
Coordinating body No coordinated approach
Anyone who creates spatial data relating to heritageResources
Guidance exists, piecemeal implementation
Research & Development Ariadne, Arena, Europeana?
If OpenStreetmap can do it…why can’t we?
