Hi,
I am wondering why a large piece of cycleway is not taken along in the April maps for NL:
https://www.openstreetmap.org/way/32441338
https://www.openstreetmap.org/relation/14020
https://www.openstreetmap.org/way/236886760
https://www.openstreetmap.org/relation/13942
https://www.openstreetmap.org/relation/8395
I checked OSM History for that part, but that has been unchanged (surely it was never removed).
Tnx!

Hi ,

Yes there is a bug related to the new
railway=abandoned
Tag.

Thats the awfull problem with the 15Tags per way limit.
I completely reworked the handling of these ways
=
Checking EVERY way for >15tags and tagtransform only the ones that exxeed this limit.

A new set of maps will be available asap.

As for the post here: It was on “hold” for no reason…
Thats WP and BBPress, a pain – I know..
Sorry !

Best regards
Christian

OK, thanks for debugging this fast! I reworked that cycleway and removed redundant tag ‘source=survey’; hope that helps a bit as well: https://www.openstreetmap.org/changeset/119537760
Many Tnx!, Frank

There will be a delay for debugged maps..
Reason: The osm database has grown too bulky – I have Java “array out ouf bounds exeptions” when sorting files for big maps.
This needs some modifikations deep inside OAM

Hi Frank,

The updated NL-Map is online – could you please check it.

Hi Frank,

I have to say thanks for bringing this issue to my attention.
I finally rewrote the 15tags trap completely new in Perl from scratch without using any existing tool.
So I was able to change the strategie from defensive – avoiding the limit to offensive = including all tags (no pre-filtering) and checking every single way (up to 1,2 million) and step by step reducing the tags to 15. In the end only a handfull of ways have to modified.

Every single way inlc route-information is checked against the tagmapping-list of OAM.

Here the priority of tags that are skipped if tags exxeed 15
my @redlist = (“mtb_scale_imba”,”surface”, “name”,”ref”,”trail_visibility”,”foot”, “bicycle”,”access”,”mtb_scale_uphill”, “mtb_scale”, “sac_scale”, “ref_hike”,”ref_cycle”,”ref_mtb”);

So in reality only the first 2 or 3 tags are skipped beginning with mtb_scale_imba

Thanks
Christian

That’s brilliant Christian! I hope the additional workload of this is acceptable for map rendering.

For the redlist – maybe we should analyze tagmapping, for me some tags with low priority are missing here, like osmc_color, piste:type… surface is actually pretty important for path analyzing in Elevate.
