Why OGC?

• Open Geospatial Consortium• www.opengeospatial.org

• ~80% of all data collected or produced by the human race ~80% of all data collected or produced by the human race is geospatially referencedis geospatially referenced

• “Helping the World to Communicate Geographically”• Any type of geospatial data• Anything that goes on a map

• A Few Current OGC Standards• Web Map Server (WMS)• Web Feature Server (WFS)• Web Coverage Server (WCS)• Catalog Service for Web (CSW)

• Commercialization of these standards• ESRI (www.esri.com)


OGC-OGF Common Objective

• Promote international standardization with the goal of providing distributed data processing capabilities for geospatial data users in a way that is:• TransparentTransparent -- the users do not have to be aware of the

exact data and computing resources they are using or the details about doing so,

• InteroperableInteroperable -- the data and computing resources can come from different sites, and

• ScalableScalable -- the same user model can service small computing tasks that can be done locally, as well as large computing tasks that require massive remote platforms.


Basic Terms of the MOU

• Renewable one-year periods• Automatically renewed unless one party provided

written notification three months in advance of non-renewal

• OGC and OGF exchange memberships for key collaboration members• Key collaboration members have full access to

both organization’s documents• OGC has members-only web site areas


Potential OGC-OGF Joint Projects 1

• Integrate OGC's Web Processing Service (WPS) with a range of "back-end" processing environments• WPS embodies a simple model• User sends data, retrieves results, or leaves on

server• Wide range of implementations possible

• Web 2.0, basic web services, local/national grid infrastructures



• Integration of WPS with workflow management tools• Multiple WPS calls may necessary to produce the

desired data products• Workloads managed by scripting languages,

compiled code, or by workflow management engines

• Swift• Simple API for Grid Applications (SAGA)• Workflow engines

DAGMan, Pegasus, Kepler, Taverna, and Triana, just to name a few



• Integration of OGC Federated Catalogues and Data Repositories with grid data movement tools• HTTP as the transport is certainly possible• Byte-IO, GridFTP, others possible• Need for secure, third-party transfers?


The Real Goal of this Workshop

• The MOU items are a point of departure

• Get motivated people together

• Identify what people really need to do

• Get efforts snowballing between meetings

• Engage key stakeholders and potential adopters from the get-go
