MARS URLs

[Barry Cotton]

Does anyone know where to find WMS URLs for Mars Data, specifically to get direct downloads from  the PDS Orbital Data site into my QGIS?

Thanks Emma.

I had already found this and thought it was gonna work but I can't make it work.

Firstly, the bit that says "To access these tiles through a WMTS client library, depending on the WMTS client library, you only need to provide the WMTS Endpoint and the full extent or bbox information." makes it look easy but I don't think QGIS is set up to do this (via Data source Manager>WMTS>etc... ).

I am able to get the Link in to my Layers browser using the ...https://trek.nasa.gov/tiles/Mars/EQ/msss_atlas_simp_clon/1.0.0/WMTSCapabilities.xml script and it looks OK but nothing comes onto my Map. I've changed the CRS, etc.

Just wanted to check if you had tried the plugin:  OpenPlanetary Tile Loader

Kind regards

Thanks for your help Emma.  I have been able to find some URLs but not many of them work.  However, the NASA/ESA database is very highly organized and I download from that and drag and drop into QGIS/Mapinfo.  FYI, I am a retired Geologist with a lifetime's experience in making Maps, of Earth.  The Mars database is too juicy for me to ignore and I intend to match the generosity of NASA and ESA who give their data freely and give something back (freely) that might help someone.
