Adding geospatial content to images

February 28th, 2018, Published in Articles: PositionIT

The Open Geospatial Consortium (OGC) seeks public comment on the GML in JPEG 2000 (GMLJP2) version 2.1 Candidate Encoding Standard. The 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. The 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 at The candidate encoding standard is available for review and comment at, with comments due by 29 March 2018.
