I am trying to add a WMS service to Google Earth Web/Online: https://earth.google.com/web
I tried importing a .kml file that works in the desktop version of GE but had no success. I also tried adding a tile overlay, which failed as well. I could not find any recommendations for working with WMS services in the google faq/ help docs or on the web. Has anyone been successful with this?
The WMS I would like to add: http://www.geoportal.rlp.de/mapbender/php/wms.php?layer_id=61675&REQUEST=GetCapabilities&VERSION=1.1.1&SERVICE=WMS&withChilds=1
WMS overlays currently work in Google Earth Pro, but they do not work in Earth v9.x (web & mobile apps) at this time.
But in Earth for web, you should be able to add a Tile Layer that loads a set of Google Map Tiles (the same tile format as you would use with the Google Maps Platform / Maps API). You need the URL for the tile layer, with the appropriate $[x], $[y] and $[level] variables (note "level" instead of "z"). You'll also want to add the N/S/E/W tile extent coordinates. And I believe it only supports 256x256 tiles at this time. Let us know how you're trying to add a tile layer, and we can try to debug that.
