[GRASS-user] vector import issues v.in.ogr

GRASS GRASS user
1

I am using latest grass v7 svn.

Today, I created a vector map by patching some raster and converting it to vector.

Thereafter, I exported it and then imported it back.

However, in the imported vector, some polygons are missing.

The centroid is visible, but the polygon is missing.

What could be the reason.

Hi Pankaj,

What format are you exporting to? The vectors in india_basins_vector.png look good.

I created this vector by r.to.vect command.
Then, I ran v.out.ogr.
And, thereafter I tried v.in.ogr. Which resulted in erroneous vector.
