No speed camera warning

[Tobias von dem Broch]

Hey

I use OSM in the free Version with the default offline maps.
Im my town is a speed camera but OSMAnd  show now warning when I drive past the camera.

Does anyone know why?
Are the camera map wrong?

I check all warnig options

speed camera:
http://frink.bplaced.de/blitzer/?zoom=16&lat=49.28241&lon=6.88615&layers=TB0

Did you select the "speed camera" poi to be displayed on the map? (On the map -> configure screen -> POI

I assume that the warming options you mean are in the Settings menu under Navigation -> show Alarms.

Hi,

thx Harry for the clue.
I enable the poi for speed cameras. Now I have a circle with no icon on the map.
I navigate again to the speed camera but i see no warnig.

what am I doing wrong?

First of all you are using old version, there it was not working yet I guess.

The speed camera should be on the road to be displayed.

You can open the bug and I could check it later.

Is your "missing" speed camera consisting of a single node that is direct on the way? Or is it a relation with an extra node besidethe street?

Look at the raw OSM data to fid out this.

Or go to osm.org and give us the permalink to that place where the speed camera is.

If I'm right, speed cam is here:
http://www.openstreetmap.org/?lat=49.282985&lon=6.883364&zoom=18&layers=M

OSM data seems correct.

Who decided to put the speed cameras in the middle of the way????

The wiki has been changed recently and I had to go check, since I couldn't figure out why people were changing the exact positions of the speed cameras I added (next to the way of course, otherwise people would hit them) to become a node on the way.

There is an enforcement relation containing a from role. OsmAnd should use this to warn users about upcoming speed cameras.

There is no such valid decision.

This is not acceptable, because this reduces level of detail.
No "tagging for apps", like no "tagging for renderer".
Please write to these mappers.

This is of course nonsense!

I do agree that from a mapping point of view it would be better to position them where they are really positioned, but did you never ask yourself why traffic lights are also positioned on the middle of the road (just like speedcams, barriers, one-way nodes (traffic signs in real life) and so forth)? Also to make it possible to hit them?

Why would speed cams be different from traffic lights and the other mentioned nodes? Please think logical.

This is logical:

A traffic cam is on the side of the road. We use an enforcement relation to indicate in what direction it is pointing (a node on the road which gets a to role), and another node on the road where a warning should be given. This node gets a from role.

Please don't advise people to tag nodes which are part of the road as speedcams. I will put them next to the road again, where they belong and in all of Belgium, OsmAND users won't get notified of the presence of speedcams.

What you can do, if you like to be a minimalist, is advice people to create an enforcement relation with just a from node. The disadvantage is that routers aren't able anymore to decide for which direction of traffic they should warn. Just like when you tag the speedcam as part of the highway. So better go all the way and add both device and to roles as well. This is how speedcams and enforcement relations have been described for at least 4 years now.

There are public databases of speed cameras external to OSM, like in POI Plaza (http://poiplaza.com/) or Robser (http://www.robser.es/) in Spain. That information is more accurate and updated than in OSM. For example, Radardroid (https://play.google.com/store/apps/details?id=com.ventel.android.radardroid.lite) uses those databases.
It would be good to be able to import POI files (not only speed cams) in Osmand (like ATM, gas stations or shops or hotels from a particular brand, etc.). This functionality is available in many navigator applications (TomTom, Garmin, Navman, Sygic, ....). I read a discussion in this forum about selecting/displaying a subset of hotels by brand name, which can be done by importing the corresponding POI file (if it exists).

In version 1.6.5 the alert is only 500 before and not 1000 also if the way is broken in 2 parts this version don t see it
