I apologize for the delay in posting to the listserve. As I am
sure it is true for you, it has been quite hectic for me.
My feeling is that we have a good definition for the
integrative element of observational data. That is, the element in which
observational data can be (and is) incorporated in existing Natural History
collections data. To reiterate;
An observation is a collection event that describes a phenomenon, and is
bound to the spatiotemporal location where it was made. Furthermore, an
observation describes an occurrence and can be linked to descriptions of
Now we can begin to talk about the methods of aggregating
observations. To do this means issues such as protocol (including
precision, accuracy, and certainty in the methods), data quality, inferring
negative data, and detectability must be addressed. It is at this point
where observational data can begin to contribute and extend the value of
the data held within biodiversity data networks.
What I would like to do is begin a discussion on
survey/monitoring techniques and issues. Specifically I would like to
develop the necessary requirements to define methodology metadata. For
example, how does one distinguish between surveys and monitoring? For
example, I consider monitoring as a protocol- driven collection of
observational data gathered repeatedly over a time series at a specific
location. Thus, I would distinguish monitoring from a survey in that a
survey documents an occurrence of an organism(s) at a location at a
particular time, and does not include repeated sampling.
Anyway, I look forward to hearing from you.
