Web Services

OSM-GB project has targeted providing a number of Web Services over the processed OSM data.


 * WMTS: Serving map tiles in PNG format.
 * WMS: The maps are available as a multi-layered WMS (Web Map Service).
 * WMS-C: This service provides WMS through a cached tile repository (Web Map Services - Cached).
 * WMS for Bugs: This is a another WMS set up for validity detection/quality improvement.
 * WFS: This service provides the raw vector data through OGC's WFS, encoded in a number of standards.
 * WFS for Bugs: The detected buggy features and their possible improvements are served as fully attributed vector layers too.

It is noticeable that WMS and WFS are designed to server tailor-made outputs for in-depth map analysis so they provide more flexibility and higher graphics quality on the cost of more processing time. On the other hand, Tile Service and WMS-C serve cached and/or pre-rendered maps, so they benefit from higher delivery speed on the cost of lower graphical quality and less flexibility for in-depth map study.

Serving Ordnance Survey's Open Data
As a part of the project and in order to facilitate the conflation between OSM and Ordnance Survey's Open Data, the project has expanded its Web Services to provide the Open Data via a OGC's WFS:


 * WFS for VMD: A multi-layered WFS that provides VectorMap District data.


 * WFS for Meridian2: Another multi-layered WFS that provides Meridian™ 2 data.

 * Astun Technology has kindly provided a cached WMS service over OSMGB data. Currently they provide the "all" layer of OSM-GB dataset in British National Grid. The WMS' URL is: http://dev.ads.astuntechnology.com/osmgb/osmgb/service
