[gdal-dev] Closing disconnected contours

[zeta]

Hi,

I have shape file from sample map, consisting of topological contours. However many contours have small gaps and I'm looking for a pointer how to connect those lines, automatically.
Does ogr have a method or maybe more generally does anyone know of a tool, that would correctly close disconnected contours, which aren't labeled?
Gaps are small - artifacts from graticules present in original image used as source for creating this vector.

Thanks
