I wondered if there was a way of downloading occurrence data that has been uploaded to GBIF since a certain date?
I want to download (via rgbif) all occurrences for a particular taxonomic group (Poaceae family) that have been uploaded to GBIF since 2014 (i.e since the last time I downloaded them).
From looking at the numbers of records, I believe that specifying the ‘year’ criteria (i.e all records from the start of 2014) will only give me occurrences made in that time frame. There must be records that are from before 2014 that have been uploaded in the time since then (the number of occurrences has increased by ~10m since 2014 but only ~1.5m are accounted for by specifying the year criteria). Is there information about when the records are uploaded? I’ve tried specifying the ‘last interpreted’ in the GBIF api to see how that influences the number of records but it seems that all records have been modified since 2014 (no change in number of records by adding that criteria).
Is there a way without downloading all the data again?
