Hi guys,
I am trying to make a new Grass location with the secant Lambert Conformal
Conic projection.
To be sure, that's this one, right?
http://www.remotesensing.org/geotiff/proj_list/lambert_conic_conformal_2sp.html
I have noticed that if I am selecting the projection parameters through the
Grass GUI dialog, and lat_0 = lat_1, the value of lat_2 doesn't seem to be
included in the projection definition (see attached screenshot
lat_2_is_gone.png).
Strange. I have replicated it here and it looks fine:
GRASS 7.0.3 (lcc):~ > g.proj -w
PROJCS["Lambert Conformal Conic",
GEOGCS["wgs84",
DATUM["WGS_1984",
SPHEROID["WGS_1984",6378137,298.257223563],
TOWGS84[0.000,0.000,0.000]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433]],
PROJECTION["Lambert_Conformal_Conic_2SP"],
PARAMETER["standard_parallel_1",65],
PARAMETER["standard_parallel_2",75],
PARAMETER["latitude_of_origin",60],
PARAMETER["central_meridian",60],
PARAMETER["false_easting",0],
PARAMETER["false_northing",0],
UNIT["Meter",1]]
In your case let_0 != lat_1, so this corresponds to the case where it
works also for Eric. It's the case when lat_0 = lat_1 that doesn't work
for him.
Testing here with grass64, grass70, grass71 it works, though (see
attached screenshot). No idea what is going wrong for you, there, Eric.
