[Qgis-user] Preview of the QGIS Earth, Sun, Moon, & Planets Plugin

[Frank M. Howell]

Calvin,

I downloaded and installed it in Win 10 x64…will install on Linux Mint 20.2 this weekend. 

If this feature is already implemented, forgive my not yet noticing it. Would it be possible to take the earth et al data and write it to the attribute table at the date/time for each location in a table?

For instance, I use RF beacon observations for Maidenhead Grid Squares using the centroid of each grid square. It would be very useful to use the date/time field from the attribute table to have the plugin retrieve the Sun’s location and save that back to the table in a new field, for each location in the table.

Is this possible?

Thanks,

Frank

It is also rather large because it contains all the data needed to run. If you are on windows and want to download a self contained windows plugin use this link to download:

If this is not the proper command for your OS then adjust it to how you install a python package. In the OSGeo4W shell you may need to run py3_env first. If py3_env gives an error then it is not needed.

There is a green plus sign in the dialog box. Click on it and then click anywhere on the map to capture the coordinate to display solar and lunar information.
