[OpenLayers-Users] SphericalMercator and SRS aliases epsg:900913, epsg:3857, epsg:3785, epsg:102113

[Andreas Hocevar]

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?

Regards,
Andreas.
