[Qgis-user] Exporting QGIS map to KML/KMZ

[Charles Dixon-Paver]

I think it would be a lot easier to use the KML Tools algorithms to iterate
over all the layers, then simply drag all the output KMZ files into Google
Earth and export the folder containing them to a consolidated KMZ file. You
can use PyQGIS, e.g:

layers = [layer for layer in QgsProject.instance().mapLayers().values()]

out_dir = 'P:/data/kml_output'

for layer in layers:
    if layer.type() == QgsMapLayer.VectorLayer:
        try:
            layer_src = str(layer.source()).replace('\\','/')
            layer_file = os.path.join(out_dir, str(layer.name()) + '.kmz')
            processing.run("kmltools:exportkmz", {
                'InputLayer': layer_src,
                'NameField': '',
                'DescriptionField': [],
                'ExportStyle': True,
                'UseGoogleIcon': None,
                'AltitudeInterpretation': 1,
                'AltitudeMode': 0,
                'AltitudeModeField': '',
                'AltitudeField': '',
                'AltitudeAddend': 0,
                'DateTimeStampField': '',
                'DateTimeBeginField': '',
                'DateTimeEndField': '',
                'PhotoField': '',
                'OutputKmz': layer_file,
                'LineWidthFactor': 2,
                'DateStampField': '',
                'TimeStampField': '',
                'DateBeginField': '',
                'TimeBeginField': '',
                'DateEndField': '',
                'TimeEndField': ''
            })
            print('Exported: ' + layer_file)
        except Exception as err:
            print(err)


Of course you could try unpack the data and stitch it in python too, but
that's not as easy... But at least the styling etc will be managed for you.
