GCS Filtering Option

[arome]

We're fetching GCS using getAvailableCoordinateReferenceSystems and would like to filter out the lat/long coordinate systems.
Is there a way to do it?

Hi,

If you're looking to only return projected CRS (filter by units), that's not currently possible through this API.

track progress: #8614

@arome - take a look at the PR here and let me know if this works: #8629

[ben-polinsky]

This has been released in iTwin.js version 5.9.0.

Apologies for the delay - let me know how it works out.

Tried it and works great, thanks!
It would have been nice if we could provide multiple units in one query, cuz right I'm forced to running multiple calls in parallel in order to filter out one CRS unit.

const nonGeographicUnits = getAvailableCRSUnits().filter((unit) => unit.toLowerCase() !== "degree"); 
const coordinateSystemsByUnit = await Promise.all(
  nonGeographicUnits.map(async (unit) => getAvailableCoordinateReferenceSystems({ unit })),
);```

Yes, that makes sense. We can make that happen.
