Re: Cycle lanes & cycle tracks - my findings and aproposal

Felix Hartmann — 2012-05-25T08:20:51

No, no,no,no....




As for changing the cycleway key values:

If we do that, we actually loose too much information. Yes, changing the 
current cycleway key, could be a rather good idea. But don't replace it 
by something not better.

If we want to change it, then we should
a) wait for the editors to support proper lane mapping
b) wait for the editors to support proper junction mapping

c) think about how to do it once the above is working and accepted. 
Don't change the cycleway key now. It ain't perfect, but with :left and 
:right it covers most situations and it isn't difficult to understand.


Some places for thought:

and

P.S. this is better placed on the tagging mailinglist

I think that you might be better of looking at the osmcoastline tool itself
for your field of application rather than starting from the shapefiles.

Cool, this might be really helpful for adding coastline rendering
support to the OSM2World slippy map. I'll have to look at the details
and will probably need to convert the shapefiles back to osm (or add
shapefile parsing support to my tools), but it definitely seems a lot
easier to work with than the raw coastline ways in the planet.

OSMCoastline / OpenStreetMapData.com

Jochen Topf — 2012-05-23T09:28:47

Hi!

In the last months I have been working on a program that extracts coastlines
(ways tagged natural=coastline) from the planet file and processes them.  It
does a similar job as the coastcheck program that was used before for this
task, but it is easier to use, much faster (minutes instead of hours) and it
can do more.

It creates land and water polygons and linestrings for the coastline. It
corrects small errors in the data before doing that. It also generates tables
with problems in the data, you can use those to fix them. (I have fixed
hundreds of problems in the last months and the coastline currently is in
a pretty good shape, but new problems are added each day...) Optionally
large polygons and linestrings are split, to make them easier and faster
to handle (Eurasafrica is one polygon with more than 4 million points).

Of course this software is Open Source, you can find it at 
https://github.com/joto/osmcoastline . The Wiki page
http://wiki.openstreetmap.org/wiki/OSMCoastline is currently just a st

Re: Cycle lanes & cycle tracks - my findings and aproposal

Lester Caine — 2012-05-22T12:38:07

THIS is exactly the problem that has yet to be addressed fully ...
While some people have no interest in 'micro-mapping', the system does need to 
manage both layers of detail transparently.

Viewing data at a larger zoom where the detail only needs to be provided as a 
tag on the base way - cycle, footpath and the like - while once zoomed in, the 
separate footpath, carriages, and other details are displayed as separate ways 
with the relevant detail such as grass verges and barriers.

I'm not sure that 'relations' fill the gap here to relate micro-details to a 
single 'macro' way. A more integral mechanism would seem to be the right way to 
handle this? As a 'cycleway' is detailed, it is automatically linked with the 
base way that it is split from? Same with footpaths on either side of a road, 
where grass verges can be included as appropriate.

What if the cycleway belongs to a highway, but they are not very close,
there is a few meters of grass in between? I think connecting of any sort
is not necessary if you just use "bicycle=no" tag on the highway.

Re: Cycle lanes & cycle tracks - my findings and aproposal

colliar — 2012-05-22T11:27:55

The major problem I have with splitting cycleways of the highway is the
missing reference to the highway. In Germany you have to use a cycleway
by law (with some exceptions) and if the cycleway and the highway are
mapped as two highways I do not get the information if the cycleway
belongs to the road (have to use) or if it is a seperate road (can use).
E.g. we need to find a solution how to connect all the objects of a road.

Cheers
Colliar

Re: Edit review: ele=0

Gregory — 2012-05-21T12:57:17

Why make automated edits?
Why not use your scripting ability to contact the users that added the
ele=0 tags, tell them you have noticed lots and ask if they are right or
wrong. Ask them how they made them, so that they are aware and don't add
more wrong ele=0 tags.
Then you can even offer to correct them for you. But this should be done
with extra filters, such as only remove tags added by a certain user in a
certain area during a certain time frame, and with the consent of the user
that added them. It would also be good for you to show the code of your
automated script to other users on the mailing list so that they can spot
if there is anything that might be wrong with it.

No need to scrap the TT software to install ttmaps, you can have both
installed. It's just that while you can run TT software and TTTracklog at
the same time, you can't run TT software while ttmaps is running. But can
choose at any time which one you want to run.

Hi.
While I think, that this kind of building number should go to the ref

import therefore should be extra careful with it.

Philip Barnes — 2012-05-20T21:46:50

Thanks for all the suggestions.

I have a TT traffic and safety camera subscription, so need to keep the
TT software, and can't drop back to the old TT version either.

Was hoping for a pointer into where TTTracklog is discussed to see if
there is any progress on an update, or if TT have introduced some real
show stopper with the new release. The pages do not mention any mailing
lists or anything.

My ultimate plan is to build a car PC/Media player/Data logger based
around a Raspberry Pi but I think availability puts that back some
months yet.

A 2nd device would be nice, so that I can have an OSM display and then
be able to use it for navigation/error checking/enhancement ideas.

What I really miss though is a possibility to comment / discuss the

You still have not provided the algorithm used to decide which objects are
changed how.

 

I have concerns that mechanical edits should only be undertaken by
experienced users and you are a 11 day user.

Thanks a lot – I can now actually see the documentation for this edit... However, there's still one major thing missing.

Please please please come back and give this simple short explanation.  I'm pretty sure you have good intentions at heart, but I can't tell what's going on until you give a description of what you're trying to do that doesn't involve 101 tables with 0 explanation of what's in them.

I hope they will not be treated together.

It's a good idea to improve quality of data in osm.
But to keep good quality, it is very important to see how the mistake came.

I think "building"="levels=N" mistake has few authors. Have you had 
contact with authors of the mistake? Have you asked them what they would

This page is out of sync with current OSMF practic. Please consider fixing.

It suggests that all discussion can be held in wiki.

DWG members point users only to mailing lists and require users to discuss
their edits on osm-hosted mailing lists only.

This page also states it is only draft. It links to not existing examples
of Mechanical Edit pages.

Existing pages do not follow this policy completely too (contact info
lacks, not in category Mechanical Edits).

There are also some valid objections to this policy in talk page.

Please discuss this policy on talk< at > list before enforcing it. Remember you
