Dans le cadre d’une thèse de doctorat en didactique de la géographie, je recherche des collègues de collège et de lycée intéressés par la mise en œuvre d’une éducation aux données dans le cadre de l’enseignement de la géographie. Ce travail tente de répondre à de récentes prescriptions, notamment l’introduction de l’apprentissage du raisonnement géographique dès le collège (2016) et la mise en place du cadre de références des compétences numériques (2019).
Concrètement, il s’agira d’élaborer ensemble une ou des séquences de cours puis de la/les tester en classe. Le travail collaboratif envisagé s’appuiera sur l’usage d’un système d’information géographique libre, QGIS. La maîtrise de cet outil n’est en aucun cas un prérequis et fera l’objet d’une formation.
Le travail collaboratif se déroulera à distance. Les réunions de travail se tiendront toutes les 7 à 8 semaines.
Vous pouvez me contacter par mail (cyrille.chopin@ac-normandie.fr) pour obtenir davantage de précisions et/ou prendre part à cette recherche collaborative. #gis #didactics #geography #education

Thematic maps for mobile: Designing thematic world maps for #mobile devices is challenging. A research team explores new, innovative map types for effective communication of spatial information on small screens.

And just the ALPRs with orientation info from deflock.me/map, showing pretty extensive coverage of all the ways into the region via 24 ALPRs, most of which are Flock devices (a few Axis ALPRs are there, too).
Aaaand now I've fleshed out the data in the map with proper tags.
Overpass-turbo query here: https://overpass-turbo.eu/s/26uS
@barefootstache @philip For mapping out the surveillance items specifically, I've been working with DeFlock, which unfortunately only does its work inside of Discord :( The tagging schema is evolving, but has largely coalesced around something like this for Flock devices:
```
camera:mount=pole
camera:type=fixed
direction=150
electricity=solar
man_made=surveillance
manufacturer=Flock Safety
manufacturer:wikidata=Q108485435
surveillance=outdoor
surveillance:type=ALPR
surveillance:zone=traffic
```
The `electricity` key can take either `solar` or `grid` as values. `surveillance:type` key's value is either `ALPR` or `gunshot_detector`, depending on the device. `surveillance:zone` key's value is typically either `traffic` or `parking`, though `entrance` can sometimes be relevant (e.g., ALPRs pointed at the gated entrances to apartment complexes).
Additional tags that are sometimes included are the `operator` and `operator:wikidata` tags. Typically, if a public info request is successfully made, it'll say who leases the cameras and other devices from Flock, and that becomes the `operator` (typically a police department). Or, if a particular entity is known to use Flock devices, such as Home Depot --- they use them across at least some of their stores' parking lots --- then that would become the operator. Ultimately though, most operators end up sharing their data with others, so who the specific operator is isn't that pertinent IMHO.
I don't think anything has been added to the OSM wiki though. Maybe I should get this info on there, since there, it will outlast any ephemeral chatter in a Discord server.
Actually, there is some guidance for Flock in Richmond, Virginia:
https://wiki.openstreetmap.org/wiki/Richmond,_Virginia/Tags#Flock_Safety
Might introduce a dedicated page to the wiki though, to get/keep everyone on the same page.
As for workflow:
1. Pick an area to survey. I do #GigWork #DoorDash, so I drive all over the place regularly. When I see a Flock device, I note the area down for follow-up survey.
2. Drive around the area, recording path with #OsmAnd (for GPX files).
3. Upon seeing a device, find a safe place to pull over.
4. Use #StreetComplete to add an initial `surveillance` (shot spotters) or `surveillance camera` (ALPRs) thing.
5. Add a note via StreetComplete with more info on the device, including orientation, and a picture if possible.
6. Go home.
7. Pull up iD, and go through my notes, fleshing out the tags on all the surveillance nodes I added early via StreetComplete.
Ho Lee Crap this region is crawling with surveillance. I mean, I kinda figured. It has a reputation as being a "bad" part of town. But damn. Dozens of Flock shot spotters, and at least a dozen ALPRs. Working on adding details to the map now. Used #StreetComplete for initial survey. Been using it often enough that I might try out adding a flow for Surveillance Things specifically rather than having to tack on notes and go back in via iD to flesh things out.

I'll tell you what is a really neat map trick (albeit, expensive). If you can find someone with a color plotter, you can take and print a topo map to Tyvek, and convert that Tyvek to an extremely lightweight ground sheet. You then have a combo LARGE SCALE map of where you are going plus a ground sheet, all wrapped up in one. Tyvek is printable, and if you physically roll it a lot (some people throw it through a washer or tumble through a dryer on air setting with shoes or something) it becomes soft like cloth. I heard (fourthhand) this may be used in the US military, in Special Ops or other applications.

@sjvn Great to see! Back when I worked in GIS and Remote Sensing, I always believed the future would be open source. QGIS has truly come a long way—yes, there’s a bit of a learning curve, but the power and flexibility it offers make it more than worth it.
