Hvilken skattekiste det er at kigge på kort. Jeg så nogle farveforskelle på naboens mark i luftfoto i #osmand som viste at uanset hvor meget landmændene gør for at dræne og slette alle forskelle, så findes vandløb og moser stadig lige under overfladen. Her er to ortofotos og et højt og et lavt målebordsblad (ca. 1865 og fra starten af 1900). Gå selv på opdagelse i dataforsyningen.dk/map/3577 og dataforsyningen.dk/map/4519 og alle de andre.

#Waydroid could be a stopgap.
What's funny is that android is so bloated (12gb of system files), that running waydroid within pmOS takes less storage space.
#OSMand seemed impressively responsive on waydroid.
But the RAM usage of all the android components is huge. Still useable, but huge. I saw memory usage shoot from 0.8GB to 2.5GB

Did you know? #Denmark has over 3,700 shelters (shelter_type=lean_to) mapped in #OpenStreetMap!
Many of these are found in peaceful, scenic spots. Together with numerous primitive campsites, they make up for the fact that we don’t have the same Allemandsret (Freedom to roam) as our Nordic neighbors.

Want to find them while out and about? Apps like #OsmAnd (using OpenStreetMap-data) make it super easy to explore and navigate to these (usually free) shelters and tent spots.

@iwmm Grundsätzlich finde ich die Funktion von OsmAnd ganz gut und relativ fortgeschritten, man muss sich aber mit den Einstellungen & Co. deutlich mehr beschäftigen als bei Komoot. Auch das Preismodell ist fair. Was mich stört, sind eine ganze Reihe Bugs bei der Routenplanung, zum Beispiel wird die Anzeige manchmal erst aktualisiert, wenn man die App beendet und wieder startet. Absolutes No-Go sind aber die unfassbar dämlichen und falschen Antworten von deren KI auf sorgfältige Reports #OsmAnd

@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:

wiki.openstreetmap.org/wiki/Ri

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.

@philip

It all depends on the level of details you want to add.

I start off with #ArmChairMapping and once have grabbed most major objects like buildings and landcover. Then I go to the streets to add more details like the values of the buildings and/or addresses.

#StreetComplete permits notes, though prefer to use #OsmAnd instead where I have created a set of quick actions to speed up the process. #EveryDoor in another favorite under #MicroMapping.

@aspensmonster

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.
