<br><font size=2 face="sans-serif">Hi,</font>
<br><font size=2 face="sans-serif">We are maiking the modification in order
to use epsg:3857 instead of 900913.</font>
<br><font size=2 face="sans-serif">We read this section: SphericalMercator
and EPSG aliases in</font>
<br><font size=2 face="sans-serif">http://trac.osgeo.org/openlayers/wiki/SphericalMercator</font>
<br>
<br><font size=2 face="sans-serif">We don't understand this part</font>
<br><font size=3 face="Times New Roman">// set transformation functions
from/to alias projection </font>
<br><font size=3 face="Times New Roman">OpenLayers.Projection.addTransform("EPSG:4326",
"EPSG:3857", OpenLayers.Layer.SphericalMercator.projectForward);
</font>
<br><font size=3 face="Times New Roman">OpenLayers.Projection.addTransform("EPSG:3857",
"EPSG:4326", OpenLayers.Layer.SphericalMercator.projectInverse);
</font><font size=2 face="sans-serif"><br>
</font>
<br><font size=2 face="sans-serif">Why is this for and when should we use
it? Do we need to do that for several epsg code?</font>
<br>
<br><font size=2 face="sans-serif">thanks for your help,</font>
