OBJECTIVE

“To provide the European Commission with a package of recommendations on policy and management measures to address coastal erosion in the EU.

These recommendations should be based on a thorough assessment of the state of coastline and of the response options available at each level of administration.”

EUROSION

Project funded by theEuropean Commission

From Data to Information

Costs and access restrictions

Most existing datasets are “copyrighted”: you do not buy information itself, but a right

to use it (“license”)

Dissemination of end-products is restricted (sometimes, end-products have to be “degraded”)

Quality “label” are not commonly adopted : uncertainty about the products

Costs and access restrictions

26% acquisition of licensed data (e.g. Elevation)

17% update of existing data (e.g. Coastal Erosion)

33% production of missing data (e.g. Hydrodynamics)

24% Format conversion, integration, and quality control

EUROSION database = 2 Millions Euros

Higher investment costs

Delayed implementation

What Is Open Geodata?

What Is “Open Geodata”?

Terminology is key to understanding principles and defining policy.

What are we talking about when we use the term ‘open geodata’?Are all stakeholders using the term equally?

Open data?1. Data Must Be Complete2. Data Must Be Primary3. Data Must Be Timely4. Data Must Be Accessible5. Data Must Be Machine processable 6. Access Must Be Non-Discriminatory7. Data Formats Must Be Non-Proprietary8. Data Must Be License-free9. Compliance must be reviewable. 10. The work shall be available as a whole and at no more than a reasonable reproduction cost

Or simply• Data without any restrictions in the use and provided for

free

What is Open Geodata?

Geodata: data referring to a location on earth

Geodata is open if any user is free to use, reuse, and redistribute it

Energy atlas Gleisdorf: solar energy and biomass potential

ThermografischeopnameOp maandagavond 26 januari2009 heeftAerodata in opdrachtvan de gemeente eenthermografischeopnamevan Delft gemaakt. Het was die avondhelder weer, zonderwind, de gemiddeldedagtemperatuur (weerstationRotterdam) was 1,1°C, met eenminimum van –2,2°C. Door beeldbewerkingvan de camera-opnamen is de warmte-uitstralingomgezet naar 6 overzichtelijkekleuren van donkerblauwtot rood. Dezekleuren zijngeenabsolute maat, maar er is uitgegaanvan de gemiddeldewarmte-uitstralingin Delft. De opname is zogedetailleerddatduidelijk is welkdeelvan het dak de meestewarmte-uitstralingheeft, of waar zich eenschoorsteenbevindt.

Ordnance Survey Open GeodataEconomic Value Study (June 2013)

Economic Assessmentnet increase in GDP of £13 to £28.5 million in 2016, from:

net productivity gains (£8 – £18.2 million) additional real tax revenues (£4.4 – £8.3 million).

increase in real GNP in the range £10.2 – £24.1 million by 2016“… an improved level of productivity in the economy, and higher overall levels of output, directly attributable to making OS OpenData free at the point of delivery.”

Financial Benefits from Open Basic DataNet returns for the public sector

“Once the initiative has been completely phased in, in 2020, there are expected savings for the public sector of about DKK 250 million per year (34 million euro ) as a result of lower administration costs.”

MetroGIS Free & Open Data

Making Public GIS Data Free and Open: Benefits and Challenges

by MetroGIS Data Producers Work Group, April 2013 MetroGIS: local geographic information systems initiative serving the seven-county Minneapolis-St. Paul (Minnesota) metropolitan area

MetroGIS - Benefits

Benefits for Public AgenciesCost savings (more efficient organizational operation).Revenue enhancement (more efficient means to collect taxes or revenue from regulatory enforcement).More efficient delivery of services to the public & efficient means of conducting agency businessImproved analytical and decision making capabilities.Enhanced ability to communicate and quantify the work of agencies to the public and policy makers.

MetroGIS – Intangible Benefits

Improves the function of a democratic society 

ensures the transparency of government and public processenables an informed & participatory citizenry and accountable governmentfosters building of relationships between organizations, public and privateimproved emergency planning preparation = increased public safety

MetroGIS – Intangible BenefitsFacilitates wider data use and enhances value

•speeds development of data-based services, tools, and applications •promotes innovation and entrepreneurship•promotes and facilitates planning, development and maintenance of physical infrastructure•promotes and facilitates understanding and preservation of natural environment•helps increase quality of the data for all, by reporting potential errors

MetroGIS – Intangible BenefitsCreates opportunities to realize cost savings

•reduces or eliminates duplication of effort for data development

•data partnerships result in cost savings on acquisition and maintenance of data

•allows organizations to more effectively deploy their resources = reduced cost

MetroGIS – Intangible BenefitsOffer improved analysis and decision making  

organizations can leverage shared data to drive core business decisionspromotes more consistent cross-jurisdictional and cross-organizational analysis and decision makingpromotes use of data from authoritative government sourcesmakes results available to a wider audience = increased confidence in the analysis and data used

MetroGIS – ChallengesChallenges to Making Data Available to Public

•Impacts on ability to engage in cost recovery for data development•Creates liability issues due to errors, omissions, and misuse•Results in a loss of control over data•Fails to provide clear, direct (financial) benefit to data providers

MetroGIS - Conclusions Agencies make a considerable investment of public funds

in GIS Data. The main challenge is to ensure that this investment produces the greatest benefit to the most people.

Public capacity to leverage this investment is growing due to advances in computing & GIS technology, and the technical capabilities of the general public (e.g. crowdsourcing, ‘location aware’ devices, etc.).

Free and open data access is a key factor in leveraging this investment.

Open and free access to data requires knowledge of the broader benefits and a commitment from the County to actively address the challenges.

MetroGIS Conclusions Challenges can be overcome, but require organization-

wide commitment. Replacing revenue collected from sale of GIS data is a

challenge to address. Counties that desire benefits for their citizens,

businesses, schools, and other institutions through free and open access to data must make decisions regarding how to fund this loss of agency revenue.

Government GIS data should be available to everyone, not just those who can afford it or for projects with sufficient ROI to justify it.
