Hi there,
I have a set of coordinates which are in a user defined projected coordinates system as bellow. Coordinates are in meters. +proj=sterea +lat_0=53.5 +lon_0=-76.0 +k=0.9996 +x_0=0.0 +y_0=0.0 +a=6378137 +b=6381816.160744 +ellps=GRS80 +units=m +no_defs The documentation says the data was transformed from Geographical Coordinate System GRS80 in QGIS database with Coordinate Reference Systems and I found one named Unknown datum based upon GRS 1980 ellipsoid with Authority ID EPSG:4019: +proj=longlat +ellps=GRS80 +no_defs Is this the GRS 80? I would like to know if I can relay in CRS with Authority ID EPSG:4019 to transform those projected coordinates back to GRS 80.
