Publishing a WMS to ArcGIS Online

RFBlandscape · ‎04-26-2023

New to ArcGIS Desktop and currently testing out publishing a raster tile to WMS for use on ArcGIS Online.

This seems to work in ArcGIS Desktop, and previews under 'My Content' in ArcGIS Online - but when I go into the Map Viewer it is "incompatible with current basemap".

This is the same regardless of which background map I show, or indeed if the background map is switched off!

Am I missing something obvious? Any help much appreciated.

Do a "GETCAPABILITIES" on the service and make sure it's showing the projections you need. For example with my service I can send it the URL in a browser:

https://giscache.clatsopcounty.gov/county-aerials/wms?REQUEST=GETCAPABILITIES

It will send back XML that includes what it knows. For the main layer it shows

<Name>county_aerials</Name>
<Title>County aerial photos</Title>
<CRS>EPSG:4258</CRS>
<CRS>EPSG:4326</CRS>
<CRS>EPSG:3857</CRS>
<CRS>EPSG:900913</CRS>
<CRS>CRS:84</CRS>

EPSG:3857 is web mercator that is what you need to see for web maps to work.

I recently went through hoops until I found I needed GLOBAL WEB MERCATOR for online maps and GLOBAL MERCATOR for printing in Web AppBuilder. But that's another story.
