Dear all,
I have a vector layer which I cleaned up using v.clean. It all appears
to be fine, but when trying to export using the libkml in v.out.ogr and
the type=area option, I am getting the warning and error messages like
below:
Warning 1: Ring Self-intersection at or near point
88.100626640406631 27.668444701473838
ERROR 6: Invalid polygon
Warning 1: Ring Self-intersection at or near point
In the resulting kml file, some of the polygons are missing. If I use
the kml output in v.out.ogr, I am not getting any warnings, but
similarly, some of the polygons are missing.
When I import the layer in Spatialite and check the geometries I am
getting similar warnings / error messages, e.g.,:
27 Ring Self-intersection at or near point 82.397900772562522 29.707213605319616
How can I identify and clean these issues in GRASS? Checking for
topological errors with v.build does not result in any error, and I
tried the various tools in v.clean to no avail.
Paulo
