Hi Alejandra,
I have a question,I am trying to use QGIS for map editing and we need the older version instead of the version 9. Where can I find the version 3.10.3-A download?
Not sure what you mean and all depend on your operating system.
We have an issue with the difference on version to finish all our templates.The issue we have is that the coordinates do not match the exact coordinates and it's only showing 4 digits instead of 14, any idea?
Seems to me that Vertex Editor only displays 4 decimals. But
coordinates values in your data source can have, will have, many
more decimals.
Moreover, you are not limited to 4 decimals when editing in Vertex
Editor, you can type "as many decimals as you want" (well,
sort of!). They will be saved in the data source but only the
rounded first four are displayed in Vertex Editor.
Looks like the it only shows 4 numbers after the decimal point making these points differentI am looking into something like this instead, with more decimal points
Hope this helps a bit!
Regards,
Benoit

You're right, they have disappeared somtime after 3.10.
Perhaps the following definitions will help you create custom crs's:

In Settings -> Custom Projections... window, use only WKT or Proj4 from above to define the projection, depending on the selected "Format" value.
Hope this helps!

Hi Benoit,
Thanks for the quick reply, but I am not seeing this in QGIS 3.14. I only see one projection: GCS_Moon_2000 (ESRI: 104903).
Kind regards,
Curt

Subject: Re: [Qgis-user] Missing lunar CRS
Hi Curt,
In QGIS 3.10 all three projections are there...
In the CRS window, in the filter box type moon and it will show at least 5 projections related to the Moon, including the three you are missing.Just reassign them to your layers.

Last year I was working on lunar terrain data using QGIS 3.8. Subsequentreleases (3.10, 3.12, 3.14) reported CRS errors when I tried to work with thesame data and projects.I have found the lunar CRS I was using in v3.8.x are missing from v3.14.1. Themissing CRS impacting my work are:* Moon 2000 (IAU2000:30100)* Moon North Pole Stereographic (IAU2000: 30118)* Moon South Pole Stereographic (IAU2000: 30120)Why were these removed from QGIS and how can they be added back in?Kind regards,Curt
