The ESRI GRID formatted LiDAR raw data file can be imported using
r.in.gdal using the appropriately defined location. Running 'gdalinfo

Looking up EPSG:4019 on the web shows me that it's an "Unknown datum based
upon the GRS 1980
ellipsoid."
I created a new location, named EPSG4019, selected that code for the
projection, and ran 'r.in.gdal -o
in=$HOME/path_to/data/topography/LDQ-45122C3/2009_OLC_Hood-to-Coast/Bare_Earth/\
be45122c3/hdr.adf out=dem2009 --overwrite' (Entered on one line; split here
for MUA accommodation.) grass75 responds,
WARNING: Datum <Not_specified_based_on_GRS_1980_ellipsoid> not recognised
by GRASS and no parameters found
Over-riding projection check
ERROR: Illegal latitude for North: 628402
Please show me what I've done incorrectly.
TIA,
Rich
