Subject: v.clean, v.digit: can't snap over 180 longitude

6.1-cvs July 2005

Hi,

I extracted a vector coastline of Antarctica from the NOAA coastline extractor
in Mapgen format (see v.in.mapgen help page for link) and imported into GRASS.
-60 to -90 lat, -180 to +180 lon.

After importing with v.in.mapgen I ran "v.clean tool=snap thresh=0.002" and
used v.digit to clean it up a bit. That's all fine but neither v.clean nor
v.digit will snap close the +180 -180 connection. I expect this will be a
problem from pole to pole?

bug or "known limitation" ?


thanks,
Hamish

There is no special support for LL, that means
-181,0 is -181,0 and vector modules don't see that point
near 179,0.

Sorry if this was too naive of me ;).

http://grass.itc.it/pipermail/grass-commit/2006-March/021025.html

Please let me know.

not sure, v.digit is currently broken in 6.3-cvs.
