Agenda

• Geospatial Big Data

• Open Geospatial Consortium

• OGC’s and Big Data

• Conclusions


OGC ®

Geospatial Big Data

• Geospatial Data has always been Big Data

• Big Data Analytics for geospatial data is available to allow

users to analyze massive volumes of geospatial data

• ESA/ESRIN "Big Data from Space" event addressed

challenges posed by policies for dissemination, data

search, sharing, transfer, mining, analysis, fusion and

visualization

• The European EarthServer project provides access to

100+ terabytes of multi-source, multi-dimensional spatio-

temporal data using standards from OGC and W3C to

provide "Big Earth Data Analytics”

• GEO/GEOSS


OGC ®

Geospatial Big Data

• The next flood of Big Data comes from mobile devices.

– Human as a sensor

– Mobile and static sensors

– Social “sensors”

• GIS moves into the cloud

– Bring “processing to the data”

• We download the earth too many times

– Accessing the Cloud using OGC Services

• WPS

• WCPS - WCS

• …

• Big processing of streaming spatial data


OGC ®

Geospatial Big Data

• Web processing Services

– The Web Processing Service (WPS) Interface Standard provides

rules for standardizing how inputs and outputs (requests and

responses) for geospatial processing services.

• The standard also defines how a client can request the execution of a

process, and how the output from the process is handled.

• The data required by the WPS can be delivered across a network or

they can be available at the server.

– TerraDue used WPS to develop a Cloud Service that allows the

dynamic deployment of algorithms on a Hadoop framework

• EC iMarine FP7

Standards are

like parachutes:

they work best

when they're

open.

OGC

• The Open GIS

Consortium (OGC)

– Not-for-profit, international

consortium of 467 industry,

government, and university

members

• Founded in 1994

• Work is based on

collaboration and

consensus!

OGC Mission

Our core mission is to deliver interface specifications that are openly available for global use, and which are used by Geospatial data producers and software transparently to the users.

OGC and Big Data

• Big Data DWG

– Interim co-chairs are Peter Baumann and John Herring, Oracle

– An open forum for work on Big Data interoperability, access, and

analytics.

– Encourage collaborative development among disparate participants,

and will ensure appropriate liaisons to other Big Data working

groups (inside and outside OGC), such as the Web Coverage

Service (WCS) SWG, RDA, and ISO. The group plans to

consolidate findings on this public wiki to inform OGC and the

greater public and allow for feedback.
