“A data publisher for community collaboration around geo-spatial data”
The first instantiation of a GeoBliki is the EO-1 Sensor Web Enabled (SWE) Data Node
to be part of the Open Geo-Spatial Consortium OWS-4 interoperability demonstration in
December 2006 which will include more than 38 organizations. The focus is centered
on a Homeland Defense scenario featuring sensors/products discovery, chem/bio
detection, satellite tasking, flood/fire image processing using service chains…
A GeoBliki is an Open Source Ruby-on-Rails application that integrates many other
open source components including Community MapBuilder and supports many of the OGC
web services: WFS, SAS, WNS, SPS, WPS...
A GeoBliki is a sensor-data node publisher. Data can be published in various forms,
which can be made accessible to local or remote users for free or for a fee. Users
can register to existing subscriptions around areas of interest and be notified via
email/IM or GeoRSS feeds when new data, comments/annotations on the existing data
Local users can access the data blog and/or the geo-wiki. The blog gives a
chronological perspective of the data while the geo-wiki allows for hierarchical
views based on user-driven topics or specific geographic features of interest. Users
are encouraged to interact with the data and/or other users about the data. Chat and
forums are built-in. Map/data annotations will be coming very soon.
Remote users or aggregators can rely on OGC services to query the database, and even
task the EO-1 satellite using the Sensor Planning Service. Identity Management
becomes a must for those capabilities. Satellite tasking could be provided at no
cost for emergency response teams for instance while for a fee to other users. OGC
GeoDRM and license management capabilities will be quickly integrated to support
these various requirements.
It is envisioned, in a very near future, that GeoBliki data nodes will be part of
larger clusters of consumers and providers within a federated and distributed
architecture of trusted nodes using standard protocols to exchange geospatial data
and build new social communities.
