Any plans. 14:07:32 RobSmith: Autonomous vehicle usage demo video 14:07:36 topic: [10 min] Future work of WebVMT and update on GeoPose (Rob Smith) 14:08:20 RobSmith: 2 csv files: 1 contains pos & orientation of vehicle; other contains lidar detections 14:08:45 RobSmith: Issue: how to turn detections into coords to plot on map 14:09:22 RobSmith: orange line is vehicle trajectory; dots represent signposts and pullouts 14:09:45 RobSmith: Puzzle to track cyclist, turn trajectory into moving feature object 14:10:13 RobSmith: Eliminate static; classify anything we see in radius as static 14:10:23 RobSmith: if in 2 consec frames, not moving 14:11:12 RobSmith: predictor algorithm yields no identity linking things together 14:11:47 RobSmith: as video moves, detections / static are eliminated 14:12:02 RobSmith: Blue trajectory is detected moving feature (cyclist) 14:12:43 RobSmith: Success; tracking algorithm isn't perfect, has gaps but pretty good 14:14:12 RobSmith: Tracked for 300m over a minute. Can calculate avg speed, etc 14:14:49 RobSmith: A car was also detected. Even short detections are useful 14:15:01 RobSmith: All tracks done with WebVMT. 14:15:24 RobSmith: Idea to release as community tool. Requires funding. 14:15:54 RobSmith: Multiple cameras, in order to associate observations. Either concurrently or 14:16:33 RobSmith: also distributed in time and space. e.g. dist along a rod, can get additional info can get info from gaps between cameras 14:16:55 RobSmith: Anonymization of reg plates on vehicles necessary. 14:17:20 meeting: SDW WG plenary telcon 14:17:26 RobSmith: Use case: traffic cameras that become stuck, showing same thing all the time, an AI could determin something wrong 14:18:24 RobSmith: Final suggestion: collision mitigation. Proximity detection for e.g. parking, or pre-emptive collision mitigation. 14:19:04 RobSmith: If combine camera deployments, traffic camera and vehicle cameras, could improve pre-emptive system 14:19:28 RobSmith: Testbed 18; if any interest in funding distribution as community tool, please get in touch 14:19:55 ClaraB: does the cyclist know he's being tracked? or is it an OS person? 14:20:21 RobSmith: All of this does have privacy implications 14:21:33 RobSmith: Other standard: geopose. Position and orientation in a common format. 14:21:59 RobSmith: Explainer videos on OGC youtube channel 14:22:46 RobSmith: GeoPose handles streams, particularly interesting for videos. 14:23:13 brinkwoman has joined #sdw 14:23:14 RobSmith: Vote at OGC for GeoPose expires early April 14:23:39 This group is working on automotive and transportaton related stuff: https://www.w3.org/auto/ 14:24:01 RobSmith: Also working on Geoalignment idea. C Perey has mobilised geopose team to get involved. 14:24:18 brinkwoman: Is GeoPose a web standard? 14:26:01 Explainer videos: https://www.youtube.com/watch?v=7qO4EU2nZlI&list=PLQsQNjNIDU86mufMCuDW0rtG2s9tHuoQ5 14:26:19 Next topic: Best Practices update from Timo 14:27:45 Timo: BP github repository: https://github.com/w3c/sdw/ 14:27:55 Testbed-17 Moving Features - Autonomous Vehicle Analysis: https://docs.ogc.org/per/21-036.html#toc51 14:28:40 Timo: improvements to coverages (clarifications) 14:29:14 Timo: addition of section on GeoPose and POI SWG activities 14:29:25 Timo: DCAT2 changes updates 14:30:26 Timo: 2 pull requests. One about FAIR principles. Now there's a mapping of which BP relates to which FAIR principle. 14:30:51 Timo: Discussion of whether FAIR should extend to include "Q" for example (quality). 14:31:40 Timo: If you define quality as fitness for purpose: if you have a use case in mind you need to have an idea of if the data is useful for that 14:31:57 Timo: Q is now included and relates to one BP in particular 14:32:32 Timo: FAIR-V verfication: does this have anything to do with FAIR? Conclusion is maybe not. 14:32:53 Timo: the PR needs some reviews, welcome from others. 14:33:15 PeterParslow: that's a good summary of the PR 14:33:36 Timo: PR about gaps in the current BP document 14:34:14 brinkwoman: inaudible 14:34:59 brinkwoman: OGC API Features, geosparql. Would be good to get a review from at least one other person. I will look at next week. 14:36:02 Timo: Issues discovered, some examples no longer accessible. Solution may be to self-host. Others possibly outdated, need revision. 14:36:26 Timo: This is a call for anyone interested to get involved. 14:36:49 Timo: section about coverages has been updated. Might be interesting to have examples of different coverage types. 14:37:22 Timo: outside our community, "coverage" is not well understood. Needs illustrations, especially in this section of document. 14:38:09 Timo: Search engine indexing. RDF-a, other approaches. Interesting to figure out what is a best practice, include in doc. 14:38:29 Timo: Dynamic CRS would be a welcome contribution to BP doc 14:38:41 Timo: TODO and future work. 14:39:11 Timo: Emerging technology, e.g. MapML. PeterR is assigned to that. 14:39:40 Timo: other tech might be interesting. If you are an expert in: POI, GeoPose, other, please PR 14:40:11 Timo: RobSmith will write a section on ethics of location sharing 14:40:26 Timo: GeoFences (volunteers needed). 14:40:41 Timo: OGC API Tiles section volunteers needed 14:41:05 Timo: TB 17 implementation reports should be scanned, volunteers needed 14:41:20 Timo: Timeline: release summer 2022 14:41:37 Timo: we have tackled 25% of anticipated changes. 14:41:53 Timo: can provide updates in SDW meetings. 14:42:27 Timo: Biweekly conference calls, next meeting 10 March 3pm CET 14:42:58 Timo: If you have something you want to discuss, please add to agenda via PR in GitHub 14:43:16 Timo: contact Timo or Clara via email or on GitHub 14:43:36 brinkwoman: thank you for update and thanks for this work 14:44:09 brinkwoman: if you would like to volunteer or discuss, please step forward! 14:47:03 brinkwoman: https://drive.verborgh.org/publications/buyle_egose_2019.pdf 14:48:00 brinkwoman: I followed up with the people who made the presentation, but haven't heard back. 14:48:37 brinkwoman: The project was very interesting. People can host their own data pod, for free. 14:49:21 brinkwoman: I was wondering if this group should do something in relation to (data pods). 14:49:41 brinkwoman: Jeremy and I discussed, thought it might be early days for this technology. 14:50:47 Timo: Here at university, we have a student who has experimented with spatial data and solid. 14:51:23 Timo: coming from linked data background, solid pods aren't implementing sparql. Not sure if that belongs in BP, maybe in emerging practices. 14:51:58 brinkwoman: If you could in a future meeting, review what the student has done, that would be of interest! 14:52:09 Timo: ok, I can summarize in a future meeting. 14:52:48 brinkwoman: People from Flanders, were using linked data event streams. Sound more lightweight method to interact with linked data. 14:53:29 Timo: Concern, if you don't have a sparql service, need to download and execute js sparql locally. Sparql 1.1 compatibility missing. 14:54:03 Timo: idea of Solid is to not overload server. Can understand removing sparql from solid server. may want to limit amount of data you download, so 14:54:15 Timo: how do you handle, no solution for now. 14:54:38 Timo: geodata you want in query, you process on client side, not sure if that is suitable at scale. 14:55:48 brinkwoman: TPAC meeting. Hybrid meeting September 12-16 in Vancouver. Remote or in-person attendance possible. 14:56:19 brinkwoman: We should determine as a group if we'll have a meeting there. Jeremy and I hope that all our work will be mostly done by then. 14:59:59 brinkwoman: 15:00:47 brinkwoman: Results: good potential for hybrid meeting 15:01:40 RRSAgent, make minutes 15:01:40 I have made the request to generate https://www.w3.org/2022/03/03-sdw-minutes.html Bert 15:16:51 s/Next topic: Best Practices update from Timo/topic: Best Practices update from Timo 15:18:25 i/https://drive.verborgh.org/publications/buyle_egose_2019.pdf/topic: [10 min] Solid - what does it mean for us?
