Hi,

Is there any planned updates to introduce the coordinate system GDA2020 (Geocentric Datum of Australia 2020 - EPSG:7844) for the image geolocations?

&nbsp;

Thanks,

Hi Malcolm,

If the desired coordinate system is not available in our database, you can import it&nbsp;using&nbsp;its \* .prj file.

This might help you to create your \*.prj file:

Hope this will help,  
Best,
