[gdal-dev] S57 and area reconstruction

[vwf]

Hello,

My question is about S57, not gdal, but one of you may be able to help 
me. 

When an area (like "prcare") is at the edge of a cell (map) there will 
be a vertex on the edge of the cel. With several cells the full area can
have several lines going through the area. Is there a trick/technique to
reconstruct the outer edge or remove the extra lines?

Thank you,
Frits
