Hello Arnd,
An option named "sphericalmercatoralias" is indeed very specific to
sphericalmercator.
Maybe, an option named "projection" is not specific
Hi,
what would people think about the following:
layer.projection -> the SRS to use in OpenLayers internally
layer.params.SRS (or layer.params.CRS etc.) -> the SRS to send to the server
Currently, we overwrite params.SRS/CRS/... with layer.projection. Nobody says
we have to.
Opinions?

Hello Arnd,
An option named "sphericalmercatoralias" is indeed very specific to
sphericalmercator.
Maybe, an option named "projection" is not specific enough. Users could
think that such an option would somehow magically allow reprojecting the
overlay projection to the map projection. Things woul

Hmm,
I didn't test my code properly, (layers without option sphericalmercator
stopped working). The following code should do better (Version >= 1.3 not
yet tested):
// override OpenLayers.WMS.getFullRequestString class member function
OpenLayers.Layer.WMS.prototype.getFullRequestString = functi
I agree with Phil, their should be built-in support for spherical mercator
aliases after all. The (now) documented work-around does not work if you
need to overlay multiple layers from providers that each support a different
alias.
The idea that Phil published seems to be the best solution I've s

good idea. AGS uses 102113 and I use an override to manage this
projection issue. eg
Ext.override(OpenLayers.Layer.WMS, {

Hi Anne,
the best way for documentation fixes/additions is to create a patch (svn diff
or unified diff) on the rst document (available in svn) and create a Trac
ticket with the patch attached. TIA.

Hello Bart,
My 2 cents:
In my opinion it is quite difficult for users to discover:
- OpenStreetMap, Google, Bing, Yahoo etc. use a projection called
'SphericalMercator'
- 'SphericalMercator' in OpenLayers uses code 'epsg:900913'
- there exist multiple aliases for 'epsg:900913' and some services
Hi Anne,
check the example (first couple of lines in comments):
http://trac.openlayers.org/browser/trunk/openlayers/examples/web-mercator.js?rev=10384
So that's up to the application to provide (at least for now). But I can
also see that's not really easy for end-users.
What do other people thi
Hello Bart,
I am not sure if

takes care of the side effect that Control.Measure and MousePosition are
no longer working properly after resetting the projection code?

Hello list,
OpenStreetMap and also some popular commercial mapservices (google,
bing, yahoo) are using the so called sphericalmercator projection.
OpenLayers has built-in support for this type of layer, inherited from
OpenLayers.Layer.SphericalMercator.
