I am trying to produce an earthquake map of the south-west pacific ocean area around New Zealand and its surrounding islands.
In order to produce a map which crosses the antimeridian, I took two ASTER dtm products and reprojected them from Pseudo Mercator EPSG:3857 to PDC Mercator EPSG:3832 which is centred on the pacific ocean
I added my earthquake data in csv format as points in EPSG:3857 and used 'save-as' to save as shapefile and then 'save-as' again to reproject them to EPSG:3832, however they still plot in exactly the same place, completely off from my reprojected dtm and at the wrong scale
The csv format looks like this (in qgis)
and they plot perfectly when i'm not trying to cross the antimeridian
Hopefully someone has an idea of what's going on and how to solve it..
I have also tried to use a layer extent to help when reprojecting the shapefiles but all this seems to do is cause me to lose all the data that is stored in the attribute tables!
