[MapQuery] WMS layered on Bing, OSM, etc.

[Steven M. Ottens]

Hi Paul,

Since OSM and BING are both in Spherical Mercator projection and 
MapQuery (nor the browser) can reproject images, the WMS has to be in 
spherical mercator as well. It is possible to combine oms, bing and WMS, 
if they are in spherical mercator, see: 
http://mapquery.org/demo/widgets/mqLayerManager.html
If you zoom in you will see the Population_Density WMS appear, and you 
can click on 'Add Bing aerial' to add the Bing layer.

Your WMS:

             {

                type:'wms',

                label:'Parcels',

                url:'http://gis.orchardparkny.org/cgi-bin/opopen.540',

                layers:'parcel_poly_2008_4326'

             }

Looks like an unprojected WGS84 (EPSG:4326) layer. This will not fit, 
you could use a reprojecting tilecache like MapProxy to convert from 
that WMS to Spherical Mercator or (even better) add support for 
Spherical Mercator to your WMS and use that.
