Working with WMS

Find out what a WMS service can do

Start with the basic URL

http://wms.oregonexplorer.info/ImageX/ecw_wms.dll?

Then add the capabilities request

http://wms.oregonexplorer.info/ImageX/ecw_wms.dll?request=GetCapabilities&service=wms

This should return an XML file with the capabilities of the server listed.

Setting the SRS

In my case, the default for this server is to return its images in the spatial referece setting "EPSG=4326" which is unprojected WGS84. What I need is Oregon state system which is "EPSG=2992"

I can add the SRS like this:

http://wms.oregonexplorer.info/ImageX/ecw_wms.dll?SRS=EPSG:2992
