Using swiss model (VSA-DSS) TEKSI/Wastewater project for wastewater in Germany?

[w0pr]

EDIT: I created an issue related to validation of german UTM32N coordinates, I totally forgot about this thread here...
#582

Is there anyone using this project/datamodel for wastewater applications in Germany (mid-size communal network)?

There is at least a rudimentary XSLT transformation from the ISYBAU external XML format used in Germany to INTERLIS (https://github.com/Robinini/isybau2interlis), so there is a way to import/export, but what about the compatibility of VSA-DSS to the german BFR-ABWASSER? It's all about pipes and manholes and water flows downwards everywhere, after all, right?

Slightly different symbology and terminology can be dealt with, but what about about the model itself? Any ideas?

Not yet to my knowledge, but we had the old version of this model (VSA-DSS 2015, now we're on the 2020 version) which was and is still used in Romania and some other countries (usually the countries with no existing country specific models)

https://github.com/QGEP/QGEP

We revamped a bit the visuals and the community around QGEP which ends out to be the TEKSI Wastewater module you know see.

I see two alternatives here,

• one is to consider having extensions and import export process for the ISIBAU.
• second is to replicate the approach and technologies provided and supported from the german model to build a similar product.

The analysis on what is the best way to go is entirely yours. Datamodel schemaspy should help you decide if the german model is similar enough to the swiss model.

As we had to make choices on how to grow on strength and sustainability for the projects and modules, we created TEKSI as a swiss association. See it as the small brother of the QGIS-CH group.

The already challenging factor is that we have already four national languages to support 😉

This is important info, so at least I am not the only crazy person.

I will definitely look at extensions; would be nice if one could use them to build a BFR Abwasser "overlay", while keeping the basic functionality of the project and profiting from development there.

I guess incorporating the big Kanton up north and standardizing on VSA-DSS is out of the question, for various reasons. 😄
