Hello, pjcozzi and kring！ When I was learning 3D Engine Design for Virtual Globes (this is a good book), I found that the url resources used in this example no longer exist. What should I change the url to make it run? I want to see the effect. Thank you very much for your answer!

Hi @gy1016, glad to hear you're enjoying the book!

It looks like the NASA tile service URL we were using is no longer valid. I think you should be able to replace the original URL in WorldWindTerrainSource.cs with https://worldwind26.arc.nasa.gov/elev?service=WMS&request=GetMap&version=1.3&crs=EPSG:4326&layers=NASA_SRTM30_900m_Tiled,aster_v2,USGS-NED&styles=&format=application/bil16&bgColor=-9999.0&width=150&height=150.

I haven't tried it though, so please let me know if that works!
