RESOLUTION: Approve last week's minutes
https://www.w3.org/2015/spatial/wiki/Patent_Call
jtandy - 1st thing... BP doc status
jtandy Doc not changed from last week... many threads via email over last week however
jtandy time consuming so docs not up to date..
jtandy Flooding scenario expanded however for particular actors results in around 12 cases studies...
jtandy - one of these where is your data, then what is your data, what format etc - so linear workflow
jtandy - Difficult to do, but will be published in next 24hrs - Good Idea ?
eparsons - Seems good keeps the doc practical
jtandy - often not possible to suggest one solution
jtandy - editors are creating content rather than editing at the moment
jtandy - new stuff from linda will come before TPAC
<jtandy> https://www.w3.org/2015/spatial/wiki/Meetings:F2F4-best-practice-agenda-scratch-pad

Payam Several discussions re coordinate systems - added a note
Payam Note - Intro and summary of discussion
Payam issue should we allow multiple coordinate systems
Payam Note as intro and then BP with more details
<Payam> https://docs.google.com/document/d/1EO70CvPJWg_dWcmgrzElUQMe6IK5OTry5S291ALQoKo/edit
Payam use eparsons doc and note as starting point... something ready for TPAC
jtandy an extension of our default CRS discussion..
<Payam> +q
jtandy - So recognise that the use of different CRS is OK
ByronCinNZ_ Lots on the topic 4326 is an OK default - not always useful however
ByronCinNZ_ Many reasons to use a different CRS however
jtandy We suggest people make a choice of data encoding, etc CRS another choice
ByronCinNZ_ GeoJSON use of WGS84 not popular with some standards organisations
Payam - several mails on using multiple CRS - is this really a BP?
roba Issue not multiple.. but identification of CRS
+1 to roba
ByronCinNZ_ Identification needs BP, multiple does not ?
roba issue if multiple and can't tell them which is whcih
<ByronCinNZ_> Sound issues
ByronCinNZ_ - Need to be more precise with language..
ByronCinNZ_ WGS84 is not really a CRS on it's own...
jtandy WGS-84 is the datum...
jtandy 5 in 20 mins
<jtandy> > describing properties that change over time
jtandy thread in agenda - but long... summary coming
jtandy - if thing changes we can use versions of geometry or position is dependent variable in time series coverage ?
jtandy - Clarifies both approaches are suggested..
roba Works when there is a authority to id features, eg. a vehicle
ByronCinNZ_ GPS tracks > GPX apprach
<scribe> topic : indirect identifiers
roba jtandy email is a good summary
roba feels over complicated to redirect
<AndreaPerego> Jeremy's (great) summary: https://lists.w3.org/Archives/Public/public-sdw-wg/2016Sep/0096.html
<jtandy> here's the summary of the thread: https://lists.w3.org/Archives/Public/public-sdw-wg/2016Sep/0096.html
roba many different angles - stability, representations, naming ...
roba difficult to conflate if representation is the same as "the thing"
roba redirect to url creates implicit relationship so - sameas ?
jtandy Long thread... worth reading !!
jtandy - Read summary
jtandy architecture of web 101 talks about indirect identification - Nadia's mail box is actually talking about Nadia
<jtandy> relative positioning, describing "fuzzy" spatial things and Linear Referencing
jtandy topic : relative positions, fuzzy boundaries , LR
jtandy help needed for spatial relations - topological relations
jtandy topological relations - which ones ??
jtandy relative location relations ? North 35m for example ?
jtandy add to TPAC discussion...
