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) ...
ERROR 1: Latitude 2764980.037140 is invalid. Valid range is [-90,90].
This warning will not be issued any more

[-180,180]. This warning will not be issued any more
9259 features written

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.
