Details: The MapPlace Lite WMS Viewer with Web Map Service (WMS) requests is available at: http://webmap.em.gov.bc.ca/mapplacewms/wmsviewer.htm. This Open Geospatial Consortium Inc. (OGC) compliant application will access most of the geospatial data that MapPlace.ca offers, such as BC Geology, Mineral Occurrences, Assessment Reports, Mineral Tenure, without the use of the MapGuide Viewer. The URL address for the WMS service, which can be used in other WMS compliant viewers, is: http://webmap.em.gov.bc.ca/liteview6.5/servlet/MapGuideLiteView.
To obtain information about the MapPlace WMS and the layers of data available, users may use the GetCapabilities request in order to generate and download an XML document containing WMS and Layer specifications. Detailed Layer information, including projections and scale dependencies can be viewed with the GetCapabilities URL request: http://webmap.em.gov.bc.ca/liteview6.5/servlet/MapGuideLiteView?VERSION=1.1.1&Request=GetCapabilities. This Capabilities document can be opened with Internet Explorer or you can view this XML Version. Some of the layers are scale dependant, such as the geology layers which are set to display below 1:1.5M scale. Layers are available as single layers and as groups of layers. The BC Geology Layer group includes several scale-dependant layers, such as Terranes, rock types, labels, contacts and faults, mineral occurrences and assessment reports. The Base Map Layer group includes the BC border, map grids, UTM grid, rivers and lakes. The BC Administrative Layer group includes mineral titles, parks, mining regions, cummunities and cities. Visible Layers will be displayed in the order listed. Thus move the layer to the bottom of the list if not visible. Use Get Map to refresh the layers.

The MapPlace Lite WMS Viewer does not allow adding multiple servers and may not handle requests from some map servers.
The Land Information BC OGC Web Map Service http://openmaps.gov.bc.ca provides these layer groups:
We have had some success using our server with other viewers, such as Manifold and ArcExplorer Webservices. However use of the Identity tool to get feature attributes in these viewers appears problematic. There may be some differences between the different viewers which will make the info tools fail.
To produce a map or to request specific map layers from the MapPlace WMS, a user or developer will have to form a parameterized URL. The URL must contain VERSION, REQUEST, SRS, BBOX, WIDTH, HEIGHT, LAYERS, STYLES and FORMAT. The details and specifics of how the URL parameters function are available on-line: http://www.opengeospatial.org. An example of a GetMap URL request:
http://webmap.em.gov.bc.ca/liteview6.5/servlet/MapGuideLiteView?REQUEST=GetMap&VERSION=1.1.1&BBOX=-121.4781,50.604,
-121.1083,50.789&WIDTH=900&HEIGHT=450&STYLES=&SRS=EPSG:4326&LAYERS=BCGS_OGC_GEOLOGY.MWF&FORMAT=image/png.
More detailed specifications can be found in the MapGuide LitevView Developers Guide at http://usa.autodesk.com/adsk/servlet/item?siteID=123112&id=3164777.
We would like to acknowledge Pacific Alliance Technologies for setting up our WMS service and Colin Ferster, our co-op student, for fine tuning the application, including layer configuration and button additions.
