What? Consultation and Implementation of- Spatial Data Infrastructures- Metadata

Why? To leverage your spatial data

How: Open Source Software- Open Standards- Agile management


INSPIRE 2011 SDI Workshop Edinburgh, UK 4/25

ESDIN is an eContentplus Best Practice Network project• Run time from September 2008 to March 2011 & ongoing• coordinated by EuroGeographics

Key goal: help member states, candidate countries and EFTA States prepare their data for INSPIRE Annex 1 spatial data themes and improve access:

1. Coordinate Reference Systems

2. Administrative Boundaries

3. Cadastral Parcels

4. Hydrography

5. Transport Networks

6. Geographical Names

CartographicEnhancement

Transform local schemas to common INSPIRE data specification framework.

Integrate INSPIRE data into compatible collaborative dataset(s).

Ensure cross-border consistency across neighbouring data.

Reduce data complexity, for effective use at alternate scales.

Modify and enhance data for mapping

purposes.


Outcomes:● Greater understanding of the technical

consequences of INSPIRE for key content stakeholders, eg, the European NMCAs

● Greater understanding of the business consequences of INSPIRE

● Wider access to geospatial digital content, eg, to the European academic sector

● Core components of the ESDI established● Operational services covering 6 INSPIRE Annex 1 themes● Test environment


Specifically the Project will (1):

Provide data for INSPIRE Annex 1 themes at a range of scales.

● "Range of scales" are realized through "varying Level of Detail"

Assess the suitability of this information as a basis for linking to other themes.

● The result are plans for a European Location Framework forming the foundation for LinkedData

http://www.linkeddata.org/


Specifically the Project will (2):

Put in place services capable of transforming and providing access to data.

● The project has successfully supported several (but not enough) NMCAs in setting up services

Develop a quality model.● Quality of originating data, processing steps,

generalization as basis for fitness of use in different domains.

WP7: Extend ExM to incorporate large scale data:

is important for large numbers of users• Transformation and generalisation services required!

WP9: NMCA Data maintenance and business processes

• Improve geospatial maintenance at the European level

– Edge-matching methodologies

– Stable Unique Identifiers

– Near real-time Change-only Updates for power users (subscription model)

Publication service integrated with production

Production with manual transformation for publication service

Service oriented productionwith semi automatic

Architecture – Addressing Stability

Publication data available through INSPIRE view and Download Servicesplus additional"mass market" formats andinterfaces.

Replication of publicationdata adapted to NMCAs processes.

Centraldata cacheallows for optimized scalabilityand availability of pan-European data

Proposed Integrated Architecture

EuroGeographicsArchitecture integrated with INSPIRE conceptual model


INSPIRE SDI Challenges● Distributed Work Teams● Availability of production quality

WFS services (eg no GML 3.2.1)● Licencing Policies● Time and manpower constraints of

participating NMCAs● Involvement of stakeholders


Adopting new Project Methodology● Introducing Scrum in WP 11 Development

● Clear definition of roles● Product Manager: focus on maximising ROI● Team: daily stand-up meetings improve focus● Scrum Master: Removes impediments

● High acceptance by development teams and management (after some positive experience)!

http://en.wikipedia.org/wiki/Scrum_(development)


Scrum Outline● Create ad hoc focused distributed teams● Maintain Product Backlog● Define Sprint Goal● Create Sprint Backlog● Iterate ● Report● Amend

ESDIN: Practical Outcomes● European Location Framework● Ready to serve as reference for LinkedData● ESDIN Architecture and Data Viewer (dev)

● Access Security using Shibboleth● Best Practice: How to get things done the

INSPIRE way● Outreach through seminars, articles, etc.

Conclusion –Prospects for the European Location Framework

• Using ESDIN best practice and tools will– Improve process efficiencies– Enable interoperability– Support users processes with

consistent, reliable reference data

• Coordination of INSPIRE data is needed

• An emergent community supports the ELF
