GML in JPEG 2000 Interoperability Experiment

This Encoding Interoperability Experiment (IE) will implement a number of prototype GMLJP2 codecs based on the specification described in the OGC Discussion Paper "GML in JPEG 2000 for Geographic Imagery". The purpose of the IE will be to confirm that the specification will support the requirements of geospatially related imagery over the Internet, and to improve the specification if it does not support these requirements.

The IE will attempt to address some of the following experiments around the use of GML in JPEG 2000 for Geospatial Imagery:
  1. Experiment #1: Minimal Instance (no schema) - Image Import/Export
  2. Experiment #2: Minimal Instance (no schema) - Read metadata
  3. Experiment #3: Application Schema - Coverage Range
  4. Experiment #4: Application Schema - Coverage Range - Image Copy
  5. Experiment #5: Application Schema - Annotated Image
  6. Experiment #6: Application Schema - Embedded CRS
  7. Experiment #7: Application Schema - Embedded Units of Measure Definition
  8. Experiment #8: Application Schema - Bundled GML features
  9. Experiment #9: Application Schema - Multi-image Case

The primary focus of this IE will be on the GML in JPEG 2000 specification, although some standards based on other OGC specifications will be invoked in order to access data or other services. The compete list of specifications that may be involved include:
  • GML in JPEG 2000 for Geospatial Imagery (GMLJP2)
  • Geography Markup Language (GML)
  • Web Feature Service (WFS)
  • Web Coverage Service (WCS)

The following documentation will comprise the deliverables for the project:
  • GMLJP2 Encoding Interoperability Experiment Report
  • Other reports may be generated as issues arise.

A demonstration of all functioning components will be made towards the end of the IE.
