[OpenLayers-Users] how to transform meters to degrees for radius paramater of st_dwithin function

[Phil Scadden]

My way of doing it. Make two points, one the centre of the circle for 
within and one x meters away. Create projection objects for both 4326 
and your webmap meter projection. If the webmap projection is not 
900913, then remember to include the projection definition script. 
Transform the points to 4326, substract and send that. I dont know 
st_dwithin (I use the above when a DWITHIN filter on WFS) but also check 
whether it expects lat/lon or lon/lat order.
