What is EDINA?


is a National Data Centre

Based at

Supported by http://pafciu17.dev.openstreetmap.org/?module=map&center=-3.18,55.935&zoom=17&width=400&height=400type=cycle

What do we do?


http://www.flickr.com/photos/steverhode/3183290111/sizes/l/in/photostream/

Ensure continuous access to resources

Preservation initiatives to ensure long term access to scholarly content

Repository services for open access and other licensed material

What do we do?


Authentication

GeoService

Geo – Digimap Collections


Geo – Accessing the data


Digimap provides access to data in several ways..............

Online mapping now with annotation...........

Download the data for use on your desktop

Geo – Digimap Openstream


Stream OS Opendata directly into:

• Web apps• Google Earth• Desktop GIS

• Preview the boundary

Places are not always just a point.What shape represents a place?Unlock API available for you to use.3 gazetteers:

• Geonames• OS Open (50k gazetteer)• OS Closed (MasterMap)• Natural Earth (soon)

What about the data?


Diagram kindly supplied by Snowflake Software

Making data available is great, but it should be in a usable format.

Where are we going?



Location Based Service – everything goes mobile…….TouchMap Lite app that streams OS Digimap OpenStream to a mobile. Not a native app.

Augmented Reality – Look at the blog for a comparison of AR browsers.

HTML 5 – making use of html 5 in particular Canvas.

What standards do we use

Just some of the standards that we publish to or use in Geo-services at EDINA

Service Standards

Digimap WMS

Digimap for Schools WMS

Openstream WMS

UKB/Open Boundaries WMS

GoGeo CSW for metadata harvesting and publishingOAI for metadata harvestingISO 19139 encoded metadata

ShareGeo OAI-PMH – for metadata harvesting

GeoDoc Xforms (user interface for forms)Xslt (XML schema transformation)eXist (xml based database management)


Standards

http://www.flickr.com/photos/epublicist/3546059144/

- Consensus approach

- Standard design by the

community for the

community

- Promotes

interoperability

- “Plug and play” when

combined

Why standards work?


Standards give you something to work towards and test against.

Not quite a recipe to follow but you know what you should end up with

Allow others to easily consume your service

Should allow different components to fit together – “plug and play”

OSGeo


OSGeo projects represent software that:

• Complies with OGC standards where possible• Is tried and tested• Is stable• Is well documented• Has a community of support around it

http://www.opengeospatial.org/standards

A project has to progress through incubation which helps achieve the criteria listed above and should install confidence in those that use the software.

Digimap case study


So, how does this work in practice?

Some figures

2010

– logins: 220,000

– Screen Maps: 6,000,000

– Print maps: 150,000

– Data downloads: 87,000

– 400,000 tiles of data (ex mastermap)

– 635,000km2 Mastermap

– 16,000,000km2 ITN

45, 000 active registered Digimap users

450 million objects in spatial databases

1.5 Tb of accessible data

Operates within tight SLA’s

We may not be a commercial outfit but our services aren’t small

Advantages


From our users point of view:• Services more functionally rich• Improved resilience

• Fall-over and machine redundancy can be offset by virtualisation and open source software stacks

From our funders point of view:• Improved service delivery with lower recurring costs• More flexibility and ability to innovate

Open standards have a definite role, vital for chaining open source products but…

• They are not an end in themselves• Not always as mature (or static) as might wish and can

evolve in short time periods

Things to think about…..


Support, documentation, development

Pick the right tool for the job – open or proprietary. Hybrid systems workSolutions should provide a flexible framework that can grow and evolve

Work towards standards, this will make services interoperable and should allow for flexible development

Proprietary vendors should integrate their product to fit your architecture

Open Source, Geo and Health Workshop

Tuesday 9th August

Napier University, Edinburgh

Free Workshop

Open Interoperability Standards

Open Source Software & Open Interoperability Standards at EDINA

• Many of EDINA’s systems implement Open Geospatial Consortium OpenGIS® interoperability standards

• While we do not offer public WFS/WMS services, we do use:• WMS, WFS, SLD, GLS, KML, GML…• Through various mapping / data download clients

• Our subscription services protected by Shibboleth authentication (implementing SAML to provide single sign-on and attribute exchange) and are free at the point of use

Hybrid Stack


We use a mix of open source and proprietary software.

Why?

Well, we believe it provides us with the best solution that fits our requirements.

Cartographic output better handled by

GoLoader and GoPublisher are great for handling Mastermap

Migrating away from this but tied to it for GoPublisher.
