[gdal-dev] import gml with curves

[Even Rouault]

Piotr,

According to http://www.datypic.com/sc/niem21/e-gml32_Curve.html, "The curve 
segments are connected to one another, with the end point of each segment 
except the last being the start point of the next segment in the segment 
list", which is not the case here. Hence the "Non contiguous curves" error 
message. So I believe your GML geometry is invalid.
