20:07:41 <tidoust> Topic: Status update of subgroups (Stats, BP)
20:08:08 <tidoust> Linda: On top of updates, Will you have a telco before the next F2F?
20:08:38 <tidoust> MichaelGordon: In the last meeting, we started to look at activities we could have to encourage adoption of the best practices.
20:09:05 <tidoust> ... I took on the task of restructuring the pages on GitHub into domain specific areas where we might want to have an impact.
20:10:56 <tidoust> ... [Michael going through a long tunnel without audio connection]
20:11:27 <MichaelGordon> Yes good idea
20:12:10 <tidoust> billroberts: About stats, we had a call 2 weeks ago where we discussed our use case document, and reviewed the document Andrea had prepared
20:12:42 <tidoust> ... Some discussion about other groups that are doing things on statistics data
20:13:01 <tidoust> ... The special angle that we're doing is on the Web part, but we need to pay attention to what others are doing as well.
20:13:19 <tidoust> ... Quite a bit of work, but we need to make sure that we have an exhaustive enough list.
20:13:55 <tidoust> ... There won't be another call before the F2F, but we'd like to spend some time at the F2F about that.
20:15:36 <tidoust> MichaelGordon: [switched phone]. Back to the SDW Best Practices. Publishing area domain might be interesting. To be discussed how people can take on some of these domains. How we could work with Denise at OGC to craft some messaging with a domain flavour.
20:15:54 <tidoust> ... We'd like some consistent theme but with some specifics.
20:16:20 <tidoust> ... Good piece of work to tackle at the F2F.
20:16:46 <tidoust> ... There is not a plan for another telecon before the F2F.
20:17:15 <tidoust> Linda: Thanks. No news on Moving Objects. I saw some activity related to SSN on GitHub
20:19:07 <tidoust> Francois: Some errata were found by an external reviewer, which led Maxime to find additional errata. To be discussed and approved by the group.
20:20:05 <tidoust> ChrisLittle: Some activity from Simon. Need to review it and make sure I get what he proposes.
20:20:31 <tidoust> Topic: Video Geotagging Protocol For Electronic Maps
20:21:21 <tidoust> Rob_Smith: From Away Team. I've been developing an idea for video geotagging. Starts from work with Ordnance Survey last year where they wanted to track position in a show.
20:21:37 <tidoust> ... The thing I discovered is that there does not appear to exist any standard for that currently.
20:22:06 <tidoust> ... Different vendors take different approaches, including embedding geolocation at the frame or metadata level.
20:22:58 <tidoust> ... It's not very accessible. Also expensive to get an add-on (only for high-end equipment) to have a GPS with your camera.
20:23:16 <tidoust> ... Now, there is an emerging market in "mobile video devices"
20:23:27 <tidoust> ... How can that need be addressed and what are the issues?
20:23:55 <tidoust> ... There are many ways to record geolocation. How to associate it with video is more problematic.
20:24:20 <tidoust> ... WebVTT support provides a hint to a possible solution. It's text-based, easy to author, accessible.
20:24:36 <tidoust> ... The file can be distributed with the video.
20:24:58 <tidoust> ... You could present geolocation data on Google Maps for instance. Camera track on a map.
20:25:26 <tidoust> ... Further value can be added by framing the map. You could annotate it to draw the user's attention to a particular feature.
20:25:50 <tidoust> ... I cornered it down to zooming, panning, and a few additional features
20:26:57 <tidoust> ... This provides cross-platform support instantaneously, and you don't need expensive equipment. A smartphone is enough for capture, and a web browser display is enough for rendering
20:27:08 <tidoust> ... Looking at use cases:
20:28:04 <tidoust> ... Coastguard/Mountain Rescue: you've got a drone searching for someone in a difficult to reach area. The remote operator can see the video, see the location on a map, and can zoom out to identify the right approach route to the person.
20:28:58 <tidoust> ... Area Survey: Drone with a detector surveying of a given area. The operator can check its work. You can fill in the area. You have improved quality insurance. No need to go to the office to analyze the footage.
20:29:31 <tidoust> ... Sports Trails: user with a helmet camera, traveling however they want. They can concentrate on their activity.
20:30:03 <tidoust> ... Speed and distance calculation can be tricky, but with this, it would already be built-in.
20:31:08 <tidoust> ... TV Coverage: the most complex one. Cameras on drones and competitors. Example of a car rally. You have multiple media devices. The director can see all of them on a map, and it can redeploy them live. It becomes an asset management system.
20:31:27 <ChrisLittle> q+
20:31:37 <tidoust> ... This concludes my presentation.
20:31:49 <tidoust> ack ChrisLittle
20:32:30 <tidoust> ChrisLittle: Thank for acknowledging SMIL/SVG on the mailing-list. Have you thought about contacting Christine Perey who is involved on Augmented Reality scenarios.
20:32:55 <tidoust> ... It may be an area to interface to, even if it does not change your idea.
20:33:25 <tidoust> ... The other connection is inside OGC is the Drone working group that just started. Their first deliverable is mission planning.
20:33:39 <tidoust> ... It may be your use case would be useful for them.
20:34:15 <tidoust> ... You may get some volunteers to help you.
20:34:52 <tidoust> Linda: Of course, in this group, we have a subgroup that will be looking at moving objects, so I see somewhat of an overlap there. They have not been active yet, though.
20:35:35 <tidoust> Rob_Smith: Just to give you a little bit of information as to where I am, I worked on a tech demo that proves things work in the browser.
20:36:22 <tidoust> ... I've worked on spatial in the past, also development for EA and Nokia.
20:36:24 <tidoust> q+
20:36:47 <tidoust> Linda: The text format that you are using to store the data, is that something like GPX?
20:37:17 <tidoust> Rob_Smith: It's a hybrid. The tech demo uses the WebVTT block structure, with a little bit of formatting at the start. It has cue times.
20:37:55 <tidoust> ... I copied that structure. I replaced the text that they used with a new markup language.
20:38:15 <tidoust> ... Thanks to Chris for the SMIL reference, I re-shaped the animation syntax to be more SMIL-like.
20:38:24 <tidoust> ... I'm looking to keeping it as lightweight as possible.
20:38:24 <ChrisLittle> q+
20:38:37 <brinkwoman> ack tidoust
20:38:48 <brinkwoman> ack ChrisLittle
20:39:28 <tidoust> ChrisLittle: You may want to steal more ideas from an OGC standard to embed positions in text messages, which is of course not very long.
20:39:41 <tidoust> Rob_Smith: Sounds like a good suggestion. Can you send me a reference?
20:39:44 <tidoust> ChrisLittle: Will do.
20:42:38 <tidoust> Francois: Media people tend to like to embed tracks within media containers. To keep in mind. Also, what usually helps in standardization groups is to sketch some sort of draft spec to drive discussions. Are you planning to do that?
20:43:02 <tidoust> Rob_Smith: Yes, I started to draft something for my own sanity.
20:43:08 <tidoust> Topic: F2F meeting
20:43:16 <brinkwoman> https://www.w3.org/2002/09/wbs/102593/sdwig-f2F-2018-q1/
20:43:42 <tidoust> Linda: A few things. First, please register or say that you are not coming. It's important for us to have this information to finalize the meeting details.
20:43:52 <brinkwoman> https://w3c.github.io/sdw/meetings/f2f-1.html
20:44:08 <tidoust> ... The logistics of the meetings should be simple enough.
20:44:24 <tidoust> ... I can take questions now if things are unclear.
20:44:44 <tidoust> ChrisLittle: When do we think that the agenda will finish on Tuesday?
20:45:23 <tidoust> Linda: A bit more than 30mn away from Shiphol airport
20:45:35 <tidoust> ... It all depends on people, I live there.
20:45:55 <tidoust> ChrisLittle: 4-5pm would work for me to get back home before midnight.
20:46:06 <tidoust> Linda: No problem on my side to stop at 4-5pm
20:46:31 <tidoust> [Ice skating logistics are being discussed]
20:48:19 <tidoust> Rough idea would be to start on Monday at 10:00am and end on Tuesday at 4-5pm.
20:48:33 <ChrisLittle> s/Shipol/Schipol/
20:48:42 <tidoust> Linda: Note I'll be there at 8 on Monday, feel free to come before.
20:48:48 <ChrisLittle> +1 to dinner
20:48:52 <tidoust> ... We'll organize a dinner on Monday night.
20:49:07 <ChrisLittle> +1 to beer
20:49:10 <tidoust> ... Agenda-wise, I want to give subgroups enough time. Any preference for slots?
20:49:45 <tidoust> billroberts: We have several Australian who are not coming to the meeting but are willing to join on WebEx for the discussion.
20:49:59 <tidoust> ... A Tuesday morning session on stats would be good from an Australian perspective.
20:50:49 <tidoust> ... From 9:00 to 10:00am on Tuesday should be not too anti-social for them.
20:51:06 <tidoust> ... We can make use of more time after that.
20:51:44 <tidoust> Linda: OK. Michael, do you have any preference?
20:53:13 <tidoust> MichaelGordon: 10:00am on a Monday would be a good slot, but a slot on Monday afternoon would be good, actually.
20:54:21 <tidoust> Linda: I'll check with folks involved in moving objects to see if they need time.
20:54:25 <tidoust> ... Should we talk about SSN?
20:54:59 <tidoust> Francois: If people are around, yes, in particular because Simon is proposing updates that go beyond errata, so future of the spec needs to be discussed.
20:55:09 <ChrisLittle> GeoSMS OGC standard for Rob Smith http://www.opengeospatial.org/standards/opengeosms
20:55:10 <tidoust> Linda: OK, if they are around.
20:55:38 <tidoust> Linda: Quick overviews of activities that are on-going at OGC and W3C would be good. Should not be long.
20:56:25 <tidoust> ... We could also discuss CityJSON, which could be a good candidate topic for joint OGC/W3C work. I can get the creator to join if needed.
20:56:46 <ChrisLittle> q+
20:56:58 <tidoust> billroberts: What can our group do to assist with that process?
20:57:09 <tidoust> ... I don't quite understand how it works.
20:57:21 <tidoust> ack ChrisLittle
20:57:49 <tidoust> ChrisLittle: One of the functions of the IG would be to triage which activities would need to be done at OGC, W3C, IETF, etc. and see where this all goes
20:57:58 <billroberts> (sorry for forgetting to use the queue properly there!)
20:58:16 <tidoust> Linda: That's something we could discuss at the F2F. How we do this triage process.
20:58:37 <MichaelGordon> +1
20:58:47 <Rob_Smith> +1
21:01:10 <tidoust> Francois: agree with Chris. Also +1 on discussing CityJSON.
21:02:08 <ChrisLittle> bye
21:02:08 <tidoust> ... I would also suggest a session to discuss other topics, either those that have already been raised such as MapML, or the presentation Rob made, as well as other topics that could come to mind to assess reactions in the room
21:02:43 <tidoust> Linda: OK, will add the meta discussion on triage process, and a session on topics to triage to the agenda.
21:03:11 <tidoust> Rob_Smith: Happy to prepare a draft spec by the F2F if that can help with the triage operation.
21:03:19 <tidoust> Linda: Can you attend the meeting or join WebEx?
21:03:30 <tidoust> Rob_Smith: Either is possible. Let's discuss offline.
21:03:43 <tidoust> Linda: Thanks. See you all at the F2F.
