OWS-9 Innovations Thread

Thread Architect: Raj Singh, OGC

The OWS-9 Innovations Thread explored cutting edge topics, and those that require the most experimental, research-oriented approaches. The topics found in this thread represented either new areas of work for the Consortium (such as GPS and Mobile Applications), a desire for new approaches to existing technologies to solve new challenges (such as the WCS work), or some combination of the two.

This thread was segmented into four overarching topics:

  • Geospatial Mobile Applications: the goal was to further understand the requirements for developing standards-based geospatially-enabled mobile applications, and to advance, test and prototype the emerging GeoPackage format, a simple structure to support data downloaded and cached onto a then disconnected mobile device that can collect data in a disconnected environment and synchronize the new data to master databases upon reconnection to the Internet.
  • Web Mapping: Diverse competing and sometimes complementary raster data tiling schemes now exist in the marketplace, including WMTS, Tile Map Service (OSGeo), MBTiles, TileCache (MetaCarta), and various others. Participants shall evaluate these approaches and recommend alignment.
  • Coverage Access and Data Quality: A number of different data formats designed for specific-purpose use may be suitable for integration into an OGC Web Services environment. The thread participants looked at NITF, LIDAR, and DAP/OPeNDAP, and investigated their re-implementation in an OWS environment with a focus on the Web Coverage Service 2.0 standard.
  • GPS Study: Advances in GPS technology and new demands on the existing system have created the need for modernization efforts to implement the next generation of GPS. Testbed participants investigated and prototyped the capabilities of OGC standards to support GPS data product and message requirements to include definition of a new one-size-fits-all Variable Message Format (VMF) message capable of supporting all potential GPS ephemeris/data.
