Gpkg or shp outputs?

What is the issue or question you have?

Folks, any plan to harmonize InVEST results shape files, either into shp or gpkg? I mean, SDR outputs a shapefile, but NDR outputs a geopackage.

What do you expect to happen?

I think geopackage is better, but shape file is the legacy standard.

What have you tried so far?

Upload the logfile using the :outbox_tray: button

Hi @JLeon , thanks for the feedback. We have discussed this internally a few times over the years. Our recent approach has been to use GeoPackage anytime we develop a new invest model or do a major refactor of an old one, where the output data is also changing in other ways. So over time we’re moving towards GeoPackage.

There are some concerns about lack of support for GeoPackage from ESRI products. I don’t think that’s stopping us from using them, but it does indicate a certain amount of disruption some users might feel when we make the change. That’s a major reason why we only make the switch when we are already changing the outputs in other ways.

But it could be that the lack of standardization across models is also annoying in its own way. That’s useful to hear about!

Would your workflow be made easier if we standardized?

Hi Dave, thanks for the fast reply!. Yes, standardization helps workflows. It could be across domains (i.e. all hydro-models (SWY,AWY,NDR,SDR) use the same output format)… and also share the same variable names for common inputs in the args (which I think is solved now).

I think geopackage is better: it produces 1/4 less output files for the same information, but also understand how important is to keep ESRI users happy.
