Hello,

I have a published WMS service that supports EPSG:27700 (projection of the map document) and EPSG:4326.  I want to leave these as supported projections but also include EPSG:3857.

I've been reading online: Defining a custom projection for a WMS service—Documentation  (10.3 and 10.3.1) | ArcGIS for Server

about defining custom projections, but the example isn't described very well and after trying a few things I'm left rather confused.

I get the impression I can Edit the WMS service via Admin by adding the listCustomCRS property, however I don't know what value(s) to set to add EPSG:3857.  The example on the page says it "overwrites the definition of EPSG:3857 using another WKT string", but I don't want to overwrite it, I want to add it.  I've tried adding the property: "listCustomCRS": "EPSG:3857=DEFAULT", but this doesn't work, it could be because "DEFAULT" needs setting to something else, but how do I find out what?

So can anyone please give me the answer, how do I add EPSG:3857 as an additionally supported projection to a WMS service which is already supporting EPSG:27700 and EPSG:4326 (without changing the projection of the source map document, this is 27700)?

Thank you.

Mark.

HI Mark,

You're right, you don't need that functionality. Please look at this topic instead: Available WMS service properties—Documentation (10.3 and 10.3.1) | ArcGIS for Server

and search/scroll down to: Additional spatial reference systems

You just need to list additional WKIDs in the properties so that they become part of the capabilities.
