The membership of the Open
Geospatial Consortium, Inc. (OGC®) is requesting comments from the
public on the candidate OpenGIS® Web Map Tiling Service (WMTS)
Interface Standard.
The candidate WMTS Interface Standard is much like the OGC"s popular
Web Map Server (WMS) Interface Standard, but it enables better server
performance in applications that involve many simultaneous requests.
To improve performance, instead of creating a new image for each
request, it returns small pre-generated images (e.g., PNG or JPEG) or
reuses identical previous requests that follow a discrete set of tile
matrices. This pronciple is used in most of the modern mapping APIs.
This proposed standard provides support for multiple
architectural patterns - KVP (Key Value Pairs),
REST
and SOAP.
The 30 day public comment period for this document begins February 27,
2009. Comments are due by March 29, 2009. After the OGC"s WMS
Standards Working Group has addressed comments received in response to
the WMTS RFC the draft documents will be submitted to the OGC
Technical Committee and Planning Committee for their review and
possible approval as an adopted OGC Standard.
The WMTS RFC can be downloaded from
