[Gdal-dev] problems with shapefiles created with v.out.ogr

[Dylan Beaudette]

Not sure what is causing this... but when i import a shape file into GRASS 
with v.in.ogr, make changes, and then export the resulting file with 
v.out.ogr, there are some geometry problems - specifically when converting 
the output shapefile into GMT-style x,y data.

The results look like the polygons are note closed (properly?)

importing the original shape file with v.in.ogr -c only made things worse -- 
incorrect attributes where assigned to polygons.

It could be that I have a slightly funky shapefile, but this problem makes me 
very wary of working with shapefile within GRASS - especially when i need to 
export the data for some other application. 

Could this be related to a badly formed shapefile, or is this part of a larger 
problem with importing/exporting shapefiles?

Any thoughts would be appreciated.

thanks in advance,
