Help.
I am attempting to use m.proj2 to transform lat/lon data to eqdc projection (Equidistant Conic). Command line seems to work fine:
-100 45
-628278.882116 362641.875369
However with an input file…
Input file:
45 0 0.0 -100 0 0.0
Output file:
11723467.724040 7394856.374043 0.0 -100 0 0.0
Now what am I doing wrong?
Thanks.

In case there is something conceptually wrong, I have included the input/output projection parameters I am using.
Input projection parameters:
ll
Ellipsoid: GRS80
Output projection parameters:
eqdc
Ellipsoid: GRS80
Ref Lat: 42N
Std. parallel 1: 37N
Std. parallel 2: 47N
Central meridian: 92W
Units: meters
H_B

[Working off the latest 5.3 version..]
The man page is out of date, and the input part of the code could use
some cleanup to accept the common lat/lon types:
DDDdMM'SSSS"
-ddd mm ssss
ddd:mm:ssssW
etc. etc. etc..
I guess checking for both the GRASS ":" way and the format cs2cs uses
should be the target.
For now, use decimal input, eastings first, in the infile & see how that
goes, e.g:
-100.0000 45.0000 any other data is just passed through
-100.5000 45.2120 any other data is just passed through
