OneGeology Launch – 33rd IGC, Oslo

20081815

Geological Map Publishing 1815 - 2008

• Time Line– 1815 first paper geological map– ~ 1990 digital cartography

• Most geological data exchange based on local databases which were originally designed to support cartography

• Proprietary software formats

• No standards, so difficult to merge data sets from different agencies

– 1994 web mapping emerges– 2005 first geological interoperable

web services test bed

Web services?

Que?

A software system that supports interoperable, machine-to-machine interaction (eg, exchanging data between computers) over a network

• data broadcast to the internet using standard internet protocols, and open source, non-proprietary data standards

• accessed by a service URL and standard requests• eg, http://www.ga.gov.au/wms/getmap?dataset=national&request=getCapabilities

OGC Web ServicesWeb Map Service vs Web Feature Service

WMS• an image (typically gif or png) of the map data• display coloured or symbolised legends• display or overlay map layers in a web browser• designed for generating and viewing maps online• point-and-click query function for simple attribute data• not designed to download the data for complex analysis• standard format for serving and requesting images of

maps, but no standard attribute structure within the data• fast delivery, simple data

OGC Web ServicesWeb Map Service vs Web Feature Service

WFS• all of the data behind the map

- may include complex, hierarchical attribute data- may include coordinates of point/line/polygon shapes- ASCII (text) format delivery for vector data

• can perform complex queries on complex data• not designed for rendering complex map shapes;

slow delivery to a map window compared to WMS images• can download the data to your desktop application• attribute structure and content governed by standard data

transfer models (eg, GeoSciML)

The OneGeology Portal

OneGeology is more than a digital map…..

• Free access to globally distributed geological data through a single internet portal

• Geological data are in a single standardised format from any OneGeology participant

• Data conforms to generic ISO and OGC standards - WMS (Web Map Service)- WFS (Web Feature Service)- GML (Geography Markup Language)

• Uses GeoSciML for WFS - a standard data transfer model and encoding for geological attribute data

OneGeology – levels of participation

• OneGeology - Level 1 - WMS; easy to set up using the cookbook provided- basic map attributes (eg, using a shapefile)- no standard attribute structure, except for a general request for attributes describing lithology and age

• OneGeology - Level 2- WFS; data transfer using GeoSciML- compliance to standard data structures and vocabularies- more complex IM and software infrastructure required

Demands of WFS delivery can expose limitations in existing information systems

Interaction and Integration of Earth Science data

• Similar international initiatives to OneGeology in other domains

– topography, water, marine and climate domains– same technology framework as OneGeology

- GML, WMS, WFS, Catalog Services, etc– OneGeology will integrate with these domains

OneGeology – where to from here?

• More sophisticated uses of Web Map Services and GeoSciML Web Feature Services

• Examples from the GeoSciML Testbed #3

- also demonstrated at 33rd IGC, Oslo

GeoSciML data in commercial applications

• ArcGIS- ESRI- and GA-developed import tool

• Oracle• GeoModeller• GSI3D• BRGM Borehole viewer

So why is OneGeology good forGA and Australia?

Because OneGeology is the same model for geoscience data delivery that we are aiming for in Australia.

We now have an operating infrastructure model that we can copy for our own.

Geological data types for an Australian Geoscience Portal

• Geological maps - GeoSciML

• Field sites - GeoSciML, O&M

• Drill holes - GeoSciML, O&M

• Mineral deposits - data model currently being tested

• Geochemistry - data model currently under development

• Geochronology - data model currently under development

• Geophysics - web coverage services (WCS) and other technologies

• Tenements - model to be developed

In conclusion…

Web services for geological data have arrived- no longer a pipe dream

• OneGeology and the GeoSciML Testbed are showcasing how WMS and WFS can be used to deliver distributed geological data in standard formats using standard protocols

• Now is the time for the Australian geological surveys to build our own ‘OneGeology’ and showcase our vast array of government geological data to the world
