[OSM-talk-be] speed limits - open data in Flanders (for some roads)

[joost schouppe]

There's a new classical tiled layer for Mapillary, so I've included it into
the speed_limits map.

Now easier than ever to spot areas where you can add speed limits with
mapillary!
(just play a bit with the map layers to get a good view)

> Hi,
>
> I discovered by chance that the AWV publishes [1] the maxspeed of all
> "gewestwegen" (N-roads and motorways) in Flanders, under the Flemish Open
> Data licence.
>
> The dataset is from July this year, and as far as I can see, of pretty
> good quality.
> If you would use it for edits, make sure the speed limit wasn't updated in
> OSM since July!
>
> At first sight, OSM agrees most of the time. But I think there's a lot of
> corrections we could do. Have a look yourself here [2]. Playing with the
> OSM Speed limits from ITO allows you to spot differences (with a bit of
> effort).
>
> I wanted to integrate a Mapillary coverage map to let you check real quick
> if there's some pictures available for ground-truthing. But while I did get
> it to work stand-alone [3], I didn't find an easy way to integrate both
> maps.
>
> If you want your own copy of the data to play with, check the Metadata
> link. You can add the WFS to QGIS and download the entire dataset there.
> There's some more interesting info in the data, like info about variable
> speed limits and lane based speeds.
> What I didn't find out yet is why some segments are present several times
> with (almost) identical geometry.
