<kerry> patent call: https://www.w3.org/2015/spatial/wiki/Patent_Call
<kerry> in http://w3c.github.io/sdw/bp/#ref-crs
<kerry> ed says: https://docs.google.com/document/d/1EO70CvPJWg_dWcmgrzElUQMe6IK5OTry5S291ALQoKo/edit?usp=sharing
joshlieberman: one of the things
we should do, if we talk about long and lat, we don't need to
talk about CRS, as it is used on the Web all the time without
CRS
... the doc explains the common pattern
<kerry> q/
kerry: ed is keen on covering this use case
joshlieberman: wgs84 is still a
CRS, it is just the smallest common denominator
... i don't want to hide the fact that people use CRS, but this
is the most common use of a CRS
ByronCinNZ: wgs84, is a
geographical projections, it makes a difference if you share
imagery
... there are some example on the web, for example from the NYT
that use very strange projections
... and there are many use cases on the Web to chose different
projections
joshlieberman: most webby people use weblocator and the software does the projection for them
ByronCinNZ: more advanced tools should be supported
kerry: what are we looking for? An introduction to the document that introduces this issue? I believe this intro is already there
ByronCinNZ: I want to see a
discussion what is a projection and why we have CRS
... in the introduction
roba: it would be better to
reference a discussion, rather than just start from scratch as
in ed's proposal
... it is not just CRS, it is about precisions and accuracy.
just recently someone killed himself because the accuracy of
his map wasn't sufficient
Linda: material is for the intro,
and I think it is a pretty good intro
... he is saying it is for 90% of the cases, but if you need
more precision you can do more
kerry: is precision something that needs to be addressed?
Linda: accuracy is particularly
important for spatial data
... there is a little bit on that in the best practises
jonblower: it is not clear to me
what is the responsibility of this group to explain. A
description of what a CRS is useful, but what is the Web link
here for us to discuss.
... there are several gotchas we better talk about, something
like lat and long is switched that is more important for Web
developers
<AndreaPerego> +1
Linda: that is a good idea. Explanation as it is now is sufficient and shouldn't be much longer
<kerry> +1
ChrisLittle: precision and
accuracy is quite a particular issue and is a safety critical
issue that should be discussed
... we should put examples about this in
... there are also two types of maps that we should explain
ByronCinNZ: I want to see an
introduction that covers the major elements, precision,
accuracy, projections
... find also some references to include
kerry: should i put this as an action against ByronCinNZ and Chris?
Linda: yes, that would be useful
<kerry> ACTION: ByronCinNZ to collect references for more info about CRs issues [recorded in http://www.w3.org/2016/08/03-sdw-minutes.html#action01]

kerry: Chris can you put this against you, as you have fallen off the IRC
<kerry> ACTION: byron cochrane to collect references for more info about CRs issues [recorded in http://www.w3.org/2016/08/03-sdw-minutes.html#action02]
<trackbot> Created ACTION-190 - Cochrane to collect references for more info about crs issues [on Byron Cochrane - due 2016-08-10].
<kerry> ACTION: linda to ask chrislittle to write something briefly about projection for BP introduction [recorded in http://www.w3.org/2016/08/03-sdw-minutes.html#action03]
<trackbot> Created ACTION-191 - Ask chrislittle to write something briefly about projection for bp introduction [on Linda van den Brink - due 2016-08-10].
<kerry> http://w3c.github.io/sdw/bp/#ref-crs
Linda: there is some text in the best practise that can go into the intro
jonblower: a lot we have written about CRS could go into the best practises
<kerry> ACTION: jonblower to draft a list of CRs gotchas for BP intro in an email [recorded in http://www.w3.org/2016/08/03-sdw-minutes.html#action04]
<trackbot> Created ACTION-192 - Draft a list of crs gotchas for bp intro in an email [on Jon Blower - due 2016-08-10].
Linda: best practise tool is in the metadata section now
Linda: jeremy and I have made
some progress, there is a new draft of the best practises for
submission on September 7th
... to discuss this draft by TPAC
<jonblower> [sorry, have to go now, bye!]
Linda: i am reordering best
practises
... please let me know if there are some best practices in a
silly place
... I sent an email around the metadata and data quality
section for comments on the list
... once I am finished with reordering I will send an email to
the list
<Linda> ? https://github.com/w3c/sdw/issues/125
Linda: some content moved to the Appendix

<trackbot> Error finding 'josh'. You can review and register nicknames at <http://www.w3.org/2015/spatial/track/users>.
Linda: jeremy proposed to add also some subheadings
<AndreaPerego> I can work on it, but in September.
<kerry> ACTION: joshlieberman to polish BP narrative including subheadings and descriptions of actors [recorded in http://www.w3.org/2016/08/03-sdw-minutes.html#action06]
<trackbot> Created ACTION-193 - Polish bp narrative including subheadings and descriptions of actors [on Joshua Lieberman - due 2016-08-10].
Linda: data on the web and spatial data on the web best practices have to be aligned still, which is not too easy
<kerry> linda, I agree this is too hard to make useful
roba: number of aspects of
spatial data where additional metadata is required, CRS units
of measure, accuracy, time dimension. What patterns are
relevant for identifying these attributes.
... taking best practises and identifying what vocabularies are
available
... how would spatial data be attached in a specific use
case
<ChrisLit> +1 to RobA
<AndreaPerego> I think that BP0 illustrated by Rob has a strong relationship with the spatial ontology Josh and Frans are working on.
<ByronCinNZ> +1
Linda: struggling to see why it should be best practice 0
roba: every best practice will say at some stage how to attach spatial data to data, this is why I propose this to be practice 0
<kerry> ACTION: roba to draft something for consideration in bp re metadata [recorded in http://www.w3.org/2016/08/03-sdw-minutes.html#action07]
<trackbot> Created ACTION-194 - Draft something for consideration in bp re metadata [on Rob Atkinson - due 2016-08-10].
<Linda> bye
<AndreaPerego> Thanks and bye
