Geospatial Crowd-Sourcing using OGC Standards
The presentation highlighted a Cloud-based (deployed on Microsoft Azure) "geo-synchronization" platform for crowd-sourced data production. The platform was demonstrated by synchronizing geospatial services from ESRI's ArcGIS Server working with SQL Server 2008 and an Oracle-based CubeWerx server. The geo-synchronization platform was developed in collaboration with US Government customers and uses emerging and established standards from OGC. What's that mean? The basic idea of a geo-synchronization service is simple - updates to a geospatial layer are published by one data source, reviewed by another and followed by others. When you hook up OGC WFS, geoRSS feeds and a geo-synch service for the task you get a federation of geospatial services and layers that can be maintained by many people working together - kinda cool and very useful.
Talking about the presentation Nuke from our office says, "If you look at the geospatial community a key emerging area are widely-used geospatial services like ArcGIS Server that offer new angles on data production. What's the angle? ArcGIS Server and other products implement Open Geospatial Consortium (OGC) WFS Transactions - a standard way to share non-imagery content. The CarbonCloud Sync platform is designed to coordinate data operations by users and synchronize these operations across different services, platforms and vendors." Other Key Points included -
- Smart synchronizing of different vendors, schemas, spatial structures
- Flexible approach to configure editing by user roles, data layers and federated services
- Standards-based architecture saves integration time and money, add new sources dynamically
- Support both base plant and crowdsourced data production at same time - with validation
The presentation was part of the FedUC that brought together government and industry professionals to explore the vision and reality of GIS (Geographic Information Systems) for the nation.
