For some reason, Quentin Groom's posts to TAXACOM don't seem to be showing up. Here is his latest post:

Subject: Re: [Taxacom] Chameleons, GBIF, and the Red List
I don't know anything about chameleons, but for a recent vascular plant
project I was working on about 60% of the data from GBIF was useful. I have
not looked into the case of chameleons, but I'm sure someone could explain why
these data are so bad and I expect many of the problems will not be general
difficulties with museum data, but specific problems of chameleons.

Yes, this shows a lack of commitment by the providers to give good quality
data, nevertheless, what they give us is still data. You should really be
complaining to your provider to get your data updated on GBIF.

In the project I mentioned above I did exactly what you are suggesting. It
took me a few minutes to get the data from GBIF providers and then a few days
to clean that up. It then took me two years to get the other 50% of the data
from various herbaria and the literature, which all needed digitizing and
georeferencing. As I'm not a polyglot nor well travelled I'm sure I did a
worse job of this than a local could have done. What you are suggesting would
be excessively expensive for all bus a few rare species.

Such things just don't exist except for a tiny fraction of rare species.

If that 4 million was dispersed to all the museums and herbaria it wouldn't be
enough to curate more than a handful of specimens. However, using GBIF you can
quickly spotted errors in your data and correct them, just as you have done.
I expect the large costs for management comes from the difficulties of getting
countries to open up their data. I'm sure they would prefer to spend their
time creating useful tools for science rather than lobbying.
