Hi Rod,

As you saw in the other message, the main problem that we have now is have the same voucher represented twice because NYBG had a DIGIR source and now have an IPT source. People at NYBG said that they ask GBIF to remove DIGIR, but still there. Maybe it occurs with other sources as well.

Related with the feedback of the data cleaning process I'm indeed interested in this discussion, but I'm not sure if this list is the best forum to do it.

Here at the National Center for Flora Conservation - CNCFlora, at the risk assessments, we just use occurrences that were validated by experts, taxonomically and spatially. This information may be useful, especially if the expert made some correction or comment on the occurrence. I can see that this is related with annotation initiatives, such as AnnoSys and FilteredPush. In my ideal and fantastic world, we would have an annotation feature on GBIF occurrences, where experts can interact with the material. In our Virtual Herbarium of Repatriated Plants, the experts can suggest new names if they have a login.

However, what is usual is the duplication of efforts for georeferencing the legacy occurrences. For example, different efforts, methodologies and uncertainty levels have been applied in different duplicates of the same occurrence, held by different herbaria.

I thought that the feedback about data improvement should be sent directly to the data provider but, please, if there is something else let me know.

Cheers,

Eduardo

Hi Eduardo,

it would be interesting to have example of the kinds of problems you encounter with GBIF data, so that we can look at was to fix the problems. It would also be interesting to know whether you would be able to provide GBIF with the corrections you make to GBIF data. It seems clear that lots of people are cleaning data in their own projects, but that doesn’t filter back to GBIF.

Regards

Rod

The problem with these tools (LontraHarvest, OpenRefine, etc.) is that they are just data *retrieval* tools, not providing for data analytical and representation functionalities

Mauro, for me this is a ​blessing! :)

At CNC Flora workflow, the data from GBIF is useless the way it is, because it have to be validated first, taxonomically and spatially. Only after the process of the cleaning, georeferencing and validation with the expert, the data will be analyzed to take part of the risk assessment.

Cheers

Eduardo
