[Qgis-user] GPS Points CRS and delete doubles

[L.W.]

Hi,

after I had imported my points correctly ... over 300.000 points

how to equalize / convert the CRS over all layers and have the same
visual output?

I like CRS 3857 more because (OSM and Google) the map looks better at
this CRS.

But the more important question for me is how to delete double points
not only by coordinate but with use of the timestamp in the same table.

Regards.
