13:06:05 <kerry> patent call: https://www.w3.org/2015/spatial/wiki/Patent_Call
13:06:32 <kerry> topic: CRS -- who is our primary audience and what do they need? And then what about the rest of them?
13:07:16 <kerry> in http://w3c.github.io/sdw/bp/#ref-crs
13:07:46 <kerry> ed says: https://docs.google.com/document/d/1EO70CvPJWg_dWcmgrzElUQMe6IK5OTry5S291ALQoKo/edit?usp=sharing
13:10:14 <ahaller2> 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
13:10:42 <ahaller2> joshlieberman: the doc explains the common pattern
13:11:03 <kerry> q/
13:11:03 <roba> q+
13:11:05 <kerry> q?
13:11:23 <ByronCinNZ> q+
13:11:35 <ahaller2> kerry: ed is keen on covering this use case
13:12:14 <ahaller2> joshlieberman: wgs84 is still a CRS, it is just the smallest common denominator
13:12:39 <kerry> q?
13:12:40 <ahaller2> joshlieberman: i don't want to hide the fact that people use CRS, but this is the most common use of a CRS
13:13:09 <ahaller2> ByronCinNZ: wgs84, is a geographical projections, it makes a difference if you share imagery
13:14:09 <ahaller2> ByronCinNZ: there are some example on the web, for example from the NYT that use very strange projections
13:14:11 <AndreaPerego> AndreaPerego has joined #sdw
13:14:27 <ahaller2> ByronCinNZ: and there are many use cases on the Web to chose different projections
13:14:29 <AndreaPerego> present+ AndreaPerego
13:14:58 <kerry> ack ByronCinNZ
13:15:08 <ahaller2> joshlieberman: most webby people use weblocator and the software does the projection for them
13:15:25 <ahaller2> ByronCinNZ: more advanced tools should be supported
13:16:08 <kerry> q?
13:16:09 <ahaller2> kerry: what are we looking for? An introduction to the document that introduces this issue? I believe this intro is already there
13:16:24 <ahaller2> ByronCinNZ: I want to see a discussion what is a projection and why we have CRS
13:16:32 <Linda> q+
13:16:34 <jonblower> q+
13:16:34 <ahaller2> ... in the introduction
13:16:48 <kerry> ack roba
13:16:51 <ChrisLittle> Q+
13:17:19 <ahaller2> roba: it would be better to reference a discussion, rather than just start from scratch as in ed's proposal
13:18:14 <ahaller2> ... 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
13:18:33 <kerry> ack linda
13:19:09 <ahaller2> Linda: material is for the intro, and I think it is a pretty good intro
13:19:57 <ahaller2> ... he is saying it is for 90% of the cases, but if you need more precision you can do more
13:20:42 <ahaller2> kerry: is precision something that needs to be addressed?
13:20:42 <ByronCinNZ> q+
13:21:00 <ahaller2> Linda: accuracy is particularly important for spatial data
13:21:40 <ahaller2> Linda: there is a little bit on that in the best practises
13:21:51 <kerry> ack jonblower
13:22:48 <ahaller2> 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.
13:24:18 <Linda> q+
13:24:32 <kerry> ack linda
13:24:33 <ahaller2> ... there are several gotchas we better talk about, something like lat and long is switched that is more important for Web developers
13:25:10 <AndreaPerego> +1
13:25:14 <ahaller2> Linda: that is a good idea. Explanation as it is now is sufficient and shouldn't be much longer
13:25:19 <kerry> +1
13:25:23 <kerry> ack ChrisLittle
13:26:18 <ahaller2> ByronCinNZ: precision and accuracy is quite a particular issue and is a safety critical issue that should be discussed
13:26:55 <ahaller2> ... we should put examples about this in
13:27:31 <ahaller2> ... there are also two types of maps that we should explain
13:27:45 <ahaller2> \me ByronCinNZ, you were hard to understand

13:29:58 <jonblower> q+
13:30:11 <ahaller2> ... find also some references to include
13:30:50 <ahaller2> kerry: should i put this as an action against ByronCinNZ and Chris?

13:46:21 <trackbot> Created ACTION-193 - Polish bp narrative including subheadings and descriptions of actors [on Joshua Lieberman - due 2016-08-10].
13:47:30 <ahaller2> ... data on the web and spatial data on the web best practices have to be aligned still, which is not too easy
13:47:54 <kerry> linda, I agree this is too hard to make useful
13:48:23 <kerry> q?
13:49:17 <kerry> q?

13:51:46 <kerry> q+
13:52:50 <ahaller2> 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.
13:53:37 <ByronCinNZ> q+
13:53:43 <kerry> ack kerry
13:55:02 <ahaller2> roba: taking best practises and identifying what vocabularies are available

13:58:03 <kerry> q?
13:58:09 <ahaller2> Linda: struggling to see why it should be best practice 0
13:59:35 <ahaller2> 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
14:00:11 <kerry> action: roba to draft something for consideration in bp re metadata
14:00:11 <trackbot> Created ACTION-194 - Draft something for consideration in bp re metadata [on Rob Atkinson - due 2016-08-10].
