Hi,
To test if the "epsg" file of MS4W is used just make some client to read a map in any supported projection (reprojected from the native) and then delete the definitions from the file. You can do it on-a-fly.
Did you already make a test with the dataset and mapfile which I pointed for you, if I remember right? They work for me here in Finland with those EPSG:97036 settings and with MS4W and I do not see any fundamental reason why they could not be made to work also for you.

I’m not a programmer so don’t have the skills to look at the code and see in what cases it would give the “Invalid SRS” error from the WMS server?

So adding it to the EPSG file does not work? If that’s the case then the sting may be incorrect.

I can get the re-projection to work just fine, but not with a ESPG code that is not already defined in the Proj espg file. For example I can go from my custom coordinate system to 3857, but I cannot serve it out using my custom code.
I think what is different about your example and mine is that in your’s case you have the EPSG code that already exists and in my case I am trying to use a new espg number that does not previously exists.
Thanks,

List your map projection and the reprojection as above and try that.

Thanks for the reply! It looks like I have everything setup right but seems like MapServer is not reading my espg file in the proj folder. Here’s the espg definition and here’s my mapfile. Or maybe it is something with the extent being requested with the SRS but everything looks right. I’m just trying to display the output image in a web browser to validate it is working.

Hi Brian, I have successfully done this as you outline below.
I checked my WMS and they reference c:\ms4w\proj\nad.
In that folder I edited the epsg file
I added the following line to the end of the file:
# ESRI Web Mercator
<102113> +proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=6378137 +b=6378137 +units=m +no_defs
Now I can serve my WMS out as Web Mercator for ArcGIS Online.

Subject: [mapserver-users] WMS Server and Custom ESPG code
I am trying to use MapServer 6.2.1 as a WMS server with a custom projection and espg code, but I keep getting this error message. msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS must be valid for all requested layers.
Is this supported? I have followed these steps.
1) Defined the custom projection with a new espg code in \ms4w\proj\nad\epsg
2) In the mapfile, I added the reference to the Proj (CONFIG "PROJ_LIB" "E:/ms4w/proj/nad")
3) Defined the new espg in the Web, Projection, Layer objects of the mapfile.
4) Verified the mapfile works using the shp2img utility
Has anyone else go this to work?
Thanks!
Brian
