Bulk file convertor QGIS plugin/program

Question

EDIT - please link any similar questions as this needs testing on QGIS 3

Similar questions have been asked but without I think non "script" solutions

Is there a easier to use for non technical users for QGIS plugin/program to bulk export files? Say shp files to .kml files?

I believe a program: Expert GPS Pro that would do this, but this $299.95 at the time of writing. (http://www.expertgps.com/)

Cannot get plugin to work based on answer

Get error: 'NoneType' object has no attribute 'CreateDataSource' See log for more details

Tried kml to shp and shp to kml Autofill settings, used Do not autofill for each test. Perhaps this plugin is better in newer QGIS versions

In QGIS 2.2:

• Output layer doesn't remember where you saving the files too
• You have to fill the output layer in multiple times. The path (location to save files isn't remembered)
• This bulk convert probably takes longer to setup than manually saving each file for a small number

How could you replicate Save Vector Layer Export settings, such as DataSource Options, Layer Options, Custom Options ect... via Creation Options Settings, so that the conversion is the "same"?

If you export kml files, I think you sometimes need to remove the altitude component via: Datasource Options, AltitudeMode: ClampToGround, so is this or other "settings" still possible via Creation Options?

I ask as I would assume you would still need to manually export files, if the settings are not "transferable" to the Convert Format.

Answer 1

Yes, there is. its called "Convert format". Go to processing toolbox and run it from there by right click then run as batch processing.

UPDATE :

put as follow in creation option column:

-dsco AltitudeMode=absolute -dsco NameField=Name -dsco DescriptionField=Description

For example, in my case will be

-dsco AltitudeMode=clampToGround -dsco NameField=NAME_1 -dsco DescriptionField=Description

TEST RESULT

Be Careful, when insert the creation option attribute (No space at the end allowed, seems it affecting the result):

Wrong → Right →

This extra description value can be modified as you need like AltitudeMode can be clampToGround or relativeToGround like the one that you see within "Save as" method.

UPDATE 2 - Alternative

-dsco altitudeModeEnum=clampToGround -dsco NameField=Name -dsco DescriptionField=description

Alternative option has been tested.

Answer 2

The answer provided by @UjeIndo seems to be the correct one although I am also unsure how to exactly use the Creation Options. But if you have loaded your shapefiles into QGIS, you could loop through each one and save it as a .kml file specifying the datasourceOptions by using the following in the Python Console:

result_path = "path/to/directory/"
for layer in QgsMapLayerRegistry.instance().mapLayers().values():
    QgsVectorFileWriter.writeAsVectorFormat(layer, result_path + layer.name(), "utf-8", None, "KML", datasourceOptions='your_text')

Answer 3

I think the best option might be the installation of the HCMGIS plugin, which has a built-in batch converter.

The plugin appears in the main top bar after installation. You can select:

HCMGIS -> Batch Converter -> Vector format converter

and next select the file extensions to convert: Shp, GeoJSON, CSV, Kml, Gpkg and Gml
