Julierme,

the issue here is that your KML file is seen as a multi-layer dataset, with
one feature per layer, so you can't use the logic you put below. You need to
merge all the layers in a single one.

You can do that with the ogrmerge.py script that comes with GDAL:
https://www.gdal.org/ogrmerge.html

$ ogrmerge.py -overwrite_ds -single -src_layer_field_name src_layer -o out.shp 
A_Cycle06.kml

With released versions of the script, this will be very slow. I've just pushed 
a fix to speed that up, so grab:
https://raw.githubusercontent.com/OSGeo/gdal/master/gdal/swig/python/scripts/ogrmerge.py

[gdal-dev] Convert KML to Shapefile PyQGIS

2019-03-18 Thread Julierme Pinheiro 
Dear all,

I have a kml file which is like a zip kml file available in here (
https://www.eorc.jaxa.jp/ALOS-2/obs/map/world_asc/kml/A_Cycle06.kml) which
has several satellite polygon footprint for Alos/Palsar images. I am in
need to convert all these files from KML to SHAPEFILE, saving the SHP files
using the layer ID.

I am trying to use the piece of code bellow (PyQGIS), but I do not know how
to unzip this kml and save the shapefiles using the layer ID information

vlayer = QgsVectorLayer("D:/KML-Images/A_Cycle06.kml", "line", "ogr")

writer = QgsVectorFileWriter.writeAsVectorFormat(vlayer,
"D:/KML-Images/.shp", "utf-8", None, "ESRI Shapefile")

Any help on that will be very appreciated.

Kind regards


Julierme
