r.plane: ValueError: invalid literal for float(): 0:04:14.5E

[neteler]

At time (besides the weird fact that the angle convention of azimuth does not match the standard GRASS convention) the easting and northing input does not accept sexagesimal input in lat-long location:

GRASS 7.2.0svn (latlong):~ >
r.plane output=plane dip=45 azimuth=9 \
  easting=0:04:14.5E northing=48:52:14.5N elev=1000 type=CELL
Traceback (most recent call last):
  File "/home/neteler/software/grass72/dist.x86_64-pc-linux-gnu/scripts/r.plane", line 128, in <module>
    main()
  File "/home/neteler/software/grass72/dist.x86_64-pc-linux-gnu/scripts/r.plane", line 78, in main
    ea = float(options['easting'])
ValueError: invalid literal for float(): 0:04:14.5E

AFAIK G_OPT_M_COORDS would support that but here the values have to be specified separately.

I guess a Python equivalent of G_scan_easting() and G_scan_northing() is needed here.

It's here: ​https://trac.osgeo.org/grass/browser/grass/trunk/lib/python/script/utils.py#L33

Please look and try r74438

Thanks, but now I get

r.plane output=plane dip=45 azimuth=9 easting=0:04:14.5E northing=48:52:14.5N elev=1000 type=CELL
ERROR: Input coordinates seems to be invalid

With debug output added locally, I see that "E" and "N" are the problem (which are accepted in g.region, see https://grass.osgeo.org/grass76/manuals/g.region.html#changing-extent-and-raster-resolution-using-values):

IMHO float_or_dms() needs an update to accept E and N.

In 74485:

libpython: float_or_dms accept E,W,N,S. see #3225
