4.4. INTERLIS Datenaustausch
This represents a guide on how to import/export data between TWW and INTERLIS 2 Transfer Format (XTF).
4.4.1. Allgemeines
The TWW plugin includes an experimental interlis import/export feature. It is currently capable of importing and exporting the following models:: * SIA405_ABWASSER_2020_1_LV95 * DSS_2020_1_LV95 * VSA_KEK_2020_1_LV95
Note that currently, exports are possible in German only. Translated exports are on the roadmap, let us know if you are interested in this feature.
4.4.2. Voraussetzungen
4.4.2.1. Java
Sie benötigen Java auf ihrem System.
Windows : Java for windows download MacOS : Java for MacOS download Linux : use the package manager
4.4.2.2. Python Bibliotheken
Sie benötigen sqlalchemy und geoalchemy2.
To install : before launching QGIS, open OSGeo4W Shell
![../../_images/osgeo4wshell.jpg](../../_images/osgeo4wshell.jpg)
and type:
>>> pip3 install "sqlalchemy~=1.3.22" "geoalchemy2>=0.9.0"
If the command fails, try:
>>> pip3 install --upgrade pip
Bemerkung
If pip cannot be found, make sure you’ve installed the python3-pip package using the OSGeo4W network installer (if you’ve installed the standalone version of QGIS, it should be included).
If this command still fails, try:
>>> pip3 install --target=c:\somewhere\other\than\the\default --upgrade pip
where c:\somewhere\other\than\the\default
is the path to your current pip package
The same –target flag can be added to install sqlalchemy and geoalchemy2 in another location.
4.4.2.3. TWW Version
The export only supports up-to-date TWW datamodel (1.5.6 at the time of writing). Ensure your datamodel is fully updated before trying to import/export.
4.4.3. Benutzung (GUI)
4.4.3.1. Aktivieren Sie den Admin-Modus
In the plugin>TWW>settings dialog, under the Developer options tab, ensure Admin mode is enabled. Restart QGIS.
![../../_images/settings_dialog.png](../../_images/settings_dialog.png)
You should now see new import and export buttons in the TWW toolbar.
![../../_images/toolbar.png](../../_images/toolbar.png)
4.4.3.2. Export
To export your TWW data, click on the export button. The following dialog will appear.
![../../_images/export_dialog.png](../../_images/export_dialog.png)
At first, select the export model.
If you have an active selection in the nodes and/or reaches layer, you can choose to restrict the export to that selection. This is especially useful in combination with the upstream/downstream selection tools.
The export tools is capable of exporting label positions for different scales. You can choose which scales you are interested in exporting by selected/deselecting them.
Bestätigen Sie das Dialogfeld und wählen Sie einen Speicherort für die .xtf-Datei.
Bemerkung
Note that windows file pathes with empty strings in the directory path or filename are not supported at the moment.
Bemerkung
Beachten Sie, dass der Befehl bei grossen/vollständigen Exporten sehr lange dauern kann.
Bemerkung
Note that QGIS standard behaviour for too long labels is to turn them horizontally (orientation = 0). You can adjust the properties of the vw_tww_reach layer - Symbology - Placement - Label overrun from „no overrun“ to e.g. 7 mm (Millimeter)
![admin-guide/interlis-io/images/layer_vw_tww_reach_label_overrun.png](admin-guide/interlis-io/images/layer_vw_tww_reach_label_overrun.png)
Bemerkung
Note that remark fields are truncated to 80 characters on INTERLIS Export, as the INTERLIS definition is like this. If you have remark fields with more text then consider to move this data to documentation with the classes „file“ and „data_media“ so it can be exported to INTERLIS completely where you can add any document, photo or video to a class.
Die Exporte enthalten einen Validierungsschritt unter Verwendung von ilivalidator, der Sie darüber informiert, ob der Export einen Validierungsfehler enthält.
4.4.3.3. Import
To import xtf`files, click on the `import button and navigate to the .xtf file.
Bemerkung
Note that windows file pathes with empty strings in the directory path or filename are not supported at the moment.
The following dialog will appear.
![../../_images/import_dialog.png](../../_images/import_dialog.png)
Im linken Teil dieses Dialogfelds werden alle Elemente aufgelistet, die aus der .xtf-Datei importiert werden sollen, so dass Sie überprüfen können, was importiert werden soll, und Elemente abwählen können, die Sie eventuell überspringen möchten. Ausserdem wird der Validierungsstatus jedes Objekts angezeigt, der angibt, ob vor dem Import weitere Massnahmen erforderlich (UNGÜLTIG) oder empfohlen (WARNUNG) sind.
Im rechten Teil dieses Dialogs wird ein Formular angezeigt, das sich auf den in der Liste ausgewählten Elementtyp bezieht und die Anpassung des Imports ermöglicht. So können z. B. „Untersuchungen“ an ihre Kanäle angehängt werden.
Wenn Sie mit den Importoptionen zufrieden sind, bestätigen Sie den Dialog, um die Änderungen in Ihrer Datenbank zu übernehmen.
4.4.4. Benutzung (Befehlszeile)
For advanced usage, the import/export tool can also be used as a command line tool.
4.4.4.1. Dependencies
The QGIS python classes must be available in the python interpreter.
On windows you can use the OSGeo4W environment
On linux you can extend the PYTHONPATH pointing to you QGIS installation, for example: export PYTHONPATH=“$PYTHONPATH:/usr/share/qgis/python“
