then I want to export it to kml and add it to the google earth, I use
the commond:
g.region vect=swi_b...@permanent v.out.ogr input=swi_b...@permanent
type=area dsn=d:/blueNew.kml layer=1 format=KML
and I got the errors:
---------------------------------------------------------------
arning 1: Layer name 'swi_b...@permanent' adjusted to
'swi_blue_PERMANENT' for XML validity.
Exporting 4893 areas (may take some time) ...

it seems that there is something wrong with the Coordinate,but
Latitude 2764980.037140 is the same with the general info from the
command v.info <http://v.info> map=''''''.
I wonder it is my problem or the grass?
On the KML page of OGR it says: "Note that KML by specification uses
only a single projection, EPSG:4326" [1]
It also says "As such OGR will create layers in the correct coordinate
system and transform any geometries."
Not sure how to interpret this, but from your error message, I would
guess that you have to reproject your vector to a epsg:4326 location
first, before exporting with v.out.ogr.

Sorry, just reread your message, and my answer is probably not really
helpful. In fact v.out.ogr does transform your data to EPSG 4326, as the
following message shows:
>> Warning 1: Longitude 638073.992861 has been modified to fit into range
>> [-180,180]. This warning will not be issued any more
No, idea what the ERROR means. What does the resulting KML file look like ?
You still might want to try to reproject (v.proj) to EPSG 4326, just to
see what happens.
