hi, if I try to make a winkel tripel location from the wx location wizard
it ends with an error that it can't parse the PROJ.4 string and the
[Finish] button never ungreys itself.
It all works fine in text mode; 'wintri' is the last entry from '`proj
-lp`', so it's not some deep & ancient custom GRASS thing PROJ.4 doesn't
know anything about.
thanks,
Hamish
ps- in future release announcements we should continue to advertise how
great the new loc wiz is. One of the common complaints from old triers of
GRASS who were used to anything-goes-projection GISs was getting
past+understanding the project (location) setup. now it's a thing of
beauty..
tested with latest 6.4svn. still happens.
"ERROR: Can't parse PROJ.4-style parameter string"
adding a debug message to g.proj's input.c (where the above error msg
comes from), the problematic string it is trying is:
{{{
+proj=wintri +lat_0=0.0 +lat_1=10.0 +lon_0=155 +ellps=wgs84 +a=6378137.000
\
+rf=298.257223563 +no_defs +no_defs
}}}
(+no_defs twice?)
from within a functioning Wintri location created using the text based
location creator (the daily earthquake map in adhoc), `g.proj -j` gives:
{{{
+proj=wintri
+lat_0=0.0000000000
+lat_1=0.0000000000
+lon_0=155.0000000000
+a=6378137
+rf=298.257223563
+no_defs
+towgs84=0.000,0.000,0.000
+to_meter=1.0
}}}
