[gdal-dev] GML to Shapefile

[Stefan Keller]

Hi,

I tried to convert a GML file to Shapefile whereas the GML contains points,
linestrings and polygons (see GML snippet below).

The command goes something like this: % ogr2ogr -f "ESRI Shapefile" outdir
mydata.gml

Now, what I'm getting out is mydata.shp (+.dbf/shx) and alayer.shp
(+.dbf/shx), where mydata contains point type and alayer contains linestring
type.  => Why is there an additional linestring shapefile but no polygon
shapefile?
