how to do when you have more than one sampling method for the same plant plot
by Rui Figueira 21 Jul '20

21 Jul '20

Dear all, One of our publishers is preparing an event based dataset with plant surveys, where two measurements were taken at each location: a Braun Blanquet Scale value and % of coverage. The normal option to create this dataset would be to make two event records for each plot, one for each survey method. This allows to preserve all original data, but will result in two occurrences for the same species at the same plot. The other option would be to report only one of the survey methods, avoiding occurrence duplication, but not preserving data for the other method. Would anyone have a suggestion how to prepare the dataset, so that it keeps values for both methods and does not create duplication of occurrences? Or the duplication is not an issue, and we should publish data for both methods?

Hi Rui, I would like to advise against creating duplicates for this purpose. For one thing, it is difficult for users to understand how (and why) to pull the information together again if it appears in two separate records. Assuming that both measurements were taken at the same location as well as time: have you considered using the "ExtendedMeasurementsOrFacts" extension (https://tools.gbif.org/dwca-validator/extension.do?id=http://rs.iobis.org/o… It seems to cover your scenario.

IPT fields mapped to GBIF API download fields?
by Simpson, Annie 08 Jul '20

08 Jul '20

I'm new to the list, and though I've looked at the archives I find them hard to maneuver (very nested; can't just 'search on page'). Can anyone point me to a reference/lookup table that maps the IPT field names and content to the names and content of the fields that are currently within a GBIF download (.xlsx example is attached, with 241 columns)? Thanks if you can, and may you be well, Annie Simpson, biologist and information scientist BioFoundational Data Team Science Analytics & Synthesis Program U.S. Geological Survey 12201 Sunrise Valley Dr. Mailstop 302 Reston VA 20192 asimpson(a)usgs.gov +1 703-648-4281 https://orcid.org/0000-0001-8338-5134
