Fetching terrain images from a web map service – February 4, 2023 at 06:16AM

I’m getting started with Web Map Service (WMS) integration into my 3D game engine. I am new to GIS but am an experienced graphics programmer.

Going by this document, the system seems extremely straightforward:
https://www.ogc.org/standards/wms

However, I am having a lot of trouble finding any working examples of a URL that fetches a patch of terrain. My goal is to fetch terrain height and color maps at various levels of detail to feed into a streaming terrain system. I imagine the request URL would be something like the following:

https://www.mapdata.com/wms/?product=moon\_height&type=map&lat=0&long=0&seconds\_x=5&seconds\_y=5&width=1024&height=1024

Can anyone here please help jump-start my learning process? Thanks in advance.
