Trouble Exporting Observations Using unobserved_by_user_id Filter

General
1

I’m trying to export a CSV of all observations for species that have not been observed by a specific user in a given location. I’ve tried using the unobserved_by_user_id parameter in the query string, but it seems to be ignored.

Example query:
place_id=9012&taxon_id=47125&unobserved_by_user_id=alex_abair

When I submit this, iNaturalist rewrites the query like this:
quality_grade=any&identifications=any&place_id=9012&taxon_id=47125&verifiable=true&spam=false

The unobserved_by_user_id parameter is stripped out or ignored, and I get all observations, not just those unobserved by the user.

I’ve tried manually editing the URL to re-insert the parameter, but it still doesn’t behave as expected.

Is this a limitation of the web interface, or an API version issue? Has anyone successfully used this filter to export CSV data?

why would you want to get observations of species not observed by you? it seems like the more common use of the parameter would be to find species not observed by you.

I’m running analyses on those observations. I’m not looking for a species list.

it’s possible to get his information via the API. if it’s not working via the CSV export, then maybe you need a feature request or bug report.

for coordinates? That’s what I do most of the time and input them into Google Maps.
