Hi all I'm trying to understand how Qgis handles coordinates extraction coming from a layer that is projected by a custom transformation.
I have a list of points in monte mario Italy zone 2 - 3004 that I want to reproject to Lat/long WGS84 with conversion between these two crs based on a NTV2 grid file. So, I load a xy temporary layer in a 3004 crs project and I save it as a shp (3004). Then I change the crs to 4326 and I use the transformation manager (transformation tool) pluigin to adjust the on the fly reprojection from 3004 to 4326 based on the NTV2 grid file. If now I try to calculate the lat/long values with field calculator with $X, $y variables Qgis returns original Monte mario metric values, right? So I must save as new 4326 shp my 3004 layer to calculate Lat/long WGS84, right? Saving to 4326 Qgis mantains the NTV2 transformation so I can calculate more accurate coordinates?
