[GRASS-user] How to make a LOCATION corresponding to JGD2000 CS III

GRASS GRASS user

Hi,

I want to create a LOCATION corresponding to JGD2000 CS III which
is defined in epsg.

I tried to create it as following,
coordinate system : Other Projection
projection name : tmerc
geodetic datum : custom
ellipsoid name : GRS80
towgs84=0,0,0,0,0,0,0
Scale Factor : 0.9999
Central Parallel : 36N

But I could not input the next item "Central Meridian".
In epsg definition, the central meridian of JGD2000 CS III is
"+lon_0=132.1666666666667", so an error message was appeared.
The message is "132.1666666666667E is invalid for longitude".

Please let me know how to create that LOCATION.

in the GUI startup you could try "create new location from EPSG code",
or the same from within another grass location with 'g.proj loc= epsg='

try 132.1666666666667 (decimal form uses +/- not E/W), or 132:10E.
