[API-users] coordinateAccurracy field

[Tim Robertson]

Hi Scott,

> Thanks for your quick responses. 

Thanks for the feedback, as always

> coordinateUncertaintyInMeters is what I wanted, thanks for pointing that out. Does that field ever show up in search results though? e.g., from /occurrence/search
>  I haven't seen it yet, but it does show up in verbatim results, e.g. http://api.gbif.org/v1/occurrence/1088909149/verbatim . But in the non-verbatim record of the same occurrence key coordinateUncertaintyInMeters isn't in the record http://api.gbif.org/v1/occurrence/1088909149/  

That looks suspicious… http://dev.gbif.org/issues/browse/POR-2795

> Anyway, my users have requested this data (i.e., coordinateUncertaintyInMeters), but going to verbatim records for each occurrence key seems like a tedious approach.   Will coordinateUncertaintyInMeters be populated in the results returned by the /occurrence/search route sometime in the future? If not, I can direct them to verbatim occurrence records. 

It should be the not too distant future, but we are short staffed right now due to holidays - I’d expect around September / October realistically before another release that involved data store changes… I wish it could be sooner.

Thanks,
Tim

Indeed http://dev.gbif.org/issues/browse/POR-2796
