27 February 2018: The Open Geospatial Consortium (OGC) seeks public comment on the GML in JPEG 2000 (GMLJP2) version 2.1 Candidate Encoding Standard.
The GMLJP2 Candidate Encoding Standard defines how the Geography Markup Language (GML) is used within JPEG 2000 images and other gridded coverage data for adding geospatial content to imagery, such as the geographic coordinates of the image, annotations, or references to features.
This 2.1 revision adds support for referenceable grid coverages via the recently published OGC Coverage Implementation Schema (CIS) extension GMLCOVRGRID, which provides additional capabilities for this standard such as support for a wide range of sensor models described with the OGC SensorML 2.0 standard or with GML-based application profiles.
Sensor models envisioned for use with this standard include mathematical descriptions of imaging systems located on satellite and airborne platforms. A full example closely based on the Community Sensor Model for frame cameras is available on-line.
The standard will appeal to:
- Developers intending to implement geospatially enabled JPEG 2000 encoders and readers;
- Developers of both WFS and WCS who wish to provide support for JPEG 2000 formats and;
- Developers who wish to use GML to give imagery a geospatial context.
The candidate GMLJP2 v2.1 Encoding Standard is available for review and comment at OGC portal. Comments are due by 29 March 2018 and should be submitted via the method outlined at on-line.
