ogr2ogr with the simplify switch does not preserve previously coincident boundaries
|Reported by:||bsh||Owned by:||warmerdam|
i have been converting a shp file to oracle spatial format using ogr2ogr with the simplify switch. while simplify works nicely and self-intersections appear minimal, there are gaps/overlaps between shared boundaries which i wasn't expecting bearing in mind the documentation says it preserves topology. is the command i am using correct and should i expect it to preserve previously coincident boundaries?
the command i am using is:
ogr2ogr -f OCI OCI:uk_atlas/uk_atlas@ C:\Projects\Customer\Ess\Census\Load\Data\Geography2\GOR_APR_2001_EN_BGC.shp -simplify 1000 -nln GOR_SMP -lco SRID=81989 -lco LAUNDER=YES -lco DIM=2 -lco GEOMETRY_NAME=GEOM -lco INDEX_PARAMETERS=TABLESPACE=UK_ATLAS
