OGC requests comment on extension that integrates OGC WCS Standard with JPEG 2000 and JPIP

OGC
Members of the Open Geospatial Consortium (OGC®) request comments on the OGC® Web Coverage Service 2.0 Interface Standard – JPEG2000/JPIP Coverage Encoding Extension – abbreviated as “JPEG2000/JPIP-Coverage”. This candidate OGC Best Practice extends version 2.0 of the OGC Web Coverage Service (WCS) Interface Standard to add support for requesting and returning coverage data formatted as JPEG 2000 (JP2), both as a static image and as a JPEG 2000 Interactive Protocol (JPIP) stream, encoded using either the classic JP2 format or the OGC GML in JPEG 2000 Encoding Standard.

The OGC WCS Standard provides an interface for requesting and returning various types of geospatial coverage information, such as satellite images, regular and irregular geospatial grids, point clouds, and meshes. JPEG 2000 (an ISO/IEC standard) is an image compression standard and coding system. JPIP, also an ISO/IEC standard, is a compression streamlining protocol that works with JPEG 2000 to produce an image using as little bandwidth as necessary. JPIP enables downloading of only the requested part of a picture, saving bandwidth, computer processing on client and server, and time. JPIP allows for the relatively quick viewing of a large image in low resolution, as well as a higher resolution part of the same image.

JPEG2000/JPIP-Coverages details can be found in the candidate OGC Best Practice  document titled OGC® Web Coverage Service 2.0 Interface Standard – JPEG2000/JPIP Coverage Encoding Extension.

This OGC candidate standard is available for review and comment athttp://www.opengeospatial.org/standards/requests/136.

The OGC is a not for profit international geospatial standards consortium of more than 500 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available standards. OGC’s open standards support interoperable solutions that “geo-enable” the Web, wireless and location-based services, and mainstream IT.
