Hi Peter & Bill

During yesterday's BP sub-group call, we went through the detailed plan for
the final sprint of BP work [1].

Most of the lucky people with actions were on the call to confirm that they
were content with their understanding of what needed to be done.

In my attempts to be organised (!) I'm just checking in with you two as you
have some bits to do...

Peter:
1/ "how to test" and "evidence" for BP5 [2]
2/ review BP5 and fix as necessary [3] ... also note Bruce Bannerman's
comments about the difference between precision and accuracy [4] and my
suggestion [5]
3/ glossary [6]

Bill:
1/ "how to test" and "evidence" for BP10 [2]
2/ continuing work on BP10 [7]
3/ file formats and vocabularies Appendix [8] (with Andrea)

(Bill - apologies as you weren't at Day 1 of the F2F, item /3/ might be new
to you)

Please confirm that you're content with these work items.

We've set our date to VOTE for the next release at Wed 26-April ... so
we'll want to FREEZE the doc a few days before that.

Jeremy

" * First para: "you can express a location to within a few metres”. This
statement ignores issues of precision and accuracy [1]. You can be as
precise as you like, but that does not make your data accurate. In relation
to the quoted text from the first paragraph, a precise coordinate that
purports to be within a few meters due to it’s coordinate precision may in
fact be inaccurate and perhaps kilometres away from that location."

"*Precision vs. accuracy*: I think we have an outstanding action to clarify our
perspective on this … I seem to recall that *Andrea Perego* offered to write
a few lines. That said, I would encourage feedback on *Best Practice 5:
Describe the positional accuracy of spatial data* [1] to make sure we have
our base concepts right. *Peter Parslow* is undertaking a review task in
this sprint."
