[gdal-dev] Extract Linestrings from GeometryCollections with ogr2gor

[Stefan Ziegler]

Thank you guys.

I used -explodecollections:

1) SHP -> GPKG
2) Clip contour lines in GPKG (this produces geometrycollections) -> GPKG
3) GPKG -> GPKG (with -explodecollections)
4) GPKG -> SHP (-nlt LINESTRING25 -skipfailures)

At the moment I have to use GDAL 1.11. With >= 2.0 there are for sure more
elegant ways (with -dialect INDIRECT_SQLITE option).

regards
Stefan
