WAYLAND, Mass.--(BUSINESS WIRE)--Feb. 19, 2003--The Open GIS
Consortium, Inc. (OGC) announces a Request for Comment (RFC) on the
proposed Web Map Context Documents Implementation Specification. This
proposed specification describes a standardized approach to enable the
capture and maintenance of the context - or state information - of a
Web Map Server (WMS) request so that this information can be reused
easily in the future user session. Those interested in this RFC are
invited to comment on the document, which is located at
www.opengis.org/info/techno/rfc16info.htm. Comments must be submitted
to OGC no later than 21 March 2003.
The "context" aspect of this RFC refers to a process to capture
and manage information transacted in WMS based requests and responses.
Information typically includes: window size and placement, bounding
box (in a common Earth coordinate reference system), URLs and other
details that could be used by another client to access the same
servers and recreate the same representation of overlaid map layers,
or to support generation of a similar map representation based on
modified parameters from the original request.
This RFC is the result of Web Services work accomplished over the
past few years as part of OGC's Interoperability Program of fast paced
testbeds and pilot projects. This program has led to a foundation of
web-based interoperability involving not only map display but also
more sophisticated geoprocessing functions, as well as location based
services, sensor and camera geolocation, web catalogs of spatial data
and spatial web services, and other capabilities.
The Canada Centre for Remote Sensing, Ionic Software (Belgium),
and US National Aeronautics and Space Administration submitted this
specification to OGC as a Request For Comment (RFC).
OGC is an international industry consortium of more than 240
companies, government agencies and universities participating in a
consensus process to develop publicly available interface
specifications. OpenGIS(R) Specifications support interoperable
solutions that "geo-enable" the Web, wireless and location-based
services, and mainstream IT. The specifications empower technology
developers to make complex spatial information and services accessible
and useful with all kinds of applications. Visit the OGC website at
