Re: [OSRM-talk] Bicycle routing, crossing large roads: how to get information on the roads crossed

2019-12-23 Per discussione Michal Palenik
I've tried it as well. no success...

similar case is for pedestrian (crossing a major, unroatable road; or
a railway; or a river with no bridge)
wheelchair users, strollers
or nordic skiing users crossing a car road

a next step would be to have a custom penalty on a node, toll booth,
stop sign, kerb (or any semi accessible barrier, stile),..

my rule of thumb proposal (from a long time age) was

Re: [OSRM-talk] new api table and geometry

2016-04-15 Per discussione Michal Palenik
that is what I already do, but it means a lot of (unnecessary)
connections. I assume the geometries are already available when
computing the duration. 

I was hoping for a "documentation lacking behind development"
scenario...

[OSRM-talk] new api table and geometry

2016-04-15 Per discussione Michal Palenik
hi, 

within the new api, I am trying to find how to get geometry (together
with perfect duration). is it possible?

or do I have to make N*M queries for all the possible combinations?

https://github.com/Project-OSRM/osrm-backend/wiki/New-Server-api#service-table

I am trying to make a service like "show me the routes to the closest
bus/tram stops" : http://epsilon.sk/mhd/

thanks

imho, the initial idea by frederik was that you (as data consumer), when
using data for nominatim/mapnik/... should be able to drop all addr:*
elements from OSM and use addr from that external data
(just as postcodes for US in nominatim are from external data and not
OSM)

importing into osm is way different area.

well, if you need just those features, then the extract is comprehensive.
by definition, there is no such thing as "narrow extract" which is not
comprehensive.

the definition of unsubstantial I'd like to pass is something like "less
than a weekend work of semi experienced mapper". a country export (by
any definition) is far far more than substantial.

Re: [OSM-legal-talk] Geocoding as produced work

2015-09-23 Per discussione Michal Palenik
I am in complete agreement with Simon.

to stress on the topic of geocoding political party donors (example), if
you don't plan to publish their individual addresses, you must not
geocode their individual specific addresses, but rather a city level
address only.

 the combined data in the most appropriate form for their purpose. We
 believe that this should be allowed so long as merged database itself is
 not being published.
 
 (answer) The non-OSM parts of a collective database do not need to be
 published.

this refers to the fact, that how databases are stored on disk does not
determine whether it is collective or derivative. saying if it's
a collective DB, you can store both parts in one SQL database. it does
not matter. 

it does not say anything about whether a produced work is based on
collective or derivative DB.

 If, however, you make a *selection* from your second database, taking

 4.6 talks about disclosure standards in cases where share-alike applies
 (offer copy of entire database or alteration file). Not sure how this
 relates?

if you publicly use a produced work (which is the indented case here)

4.4.c. Derivative Databases and Produced Works. A Derivative Database is
 Publicly Used and so must comply with Section 4.4. if a Produced Work
 created from the Derivative Database is Publicly Used.

which say, that it does not matter whether you declare geocodes produced
work or derivative db. if this didn't exist, i could declare anything
a produced work (things like any enhanced database) and the whold odbl
would not exists.

produced work is always based on a derivative db or collective db (if
they are used independetly)

4.6. restates this.

so the real question is, which part is derivative db (and not whether
it's produced work)

we consider one day work to be

- 400 adress points on area smaller than X
- outines of 200 features where good imaginery is present (only
  outlines, no other tags)

or number divided by 3 if area is larrger than X

there would be some technical discussion on all the rules, but the

 Usage may be different, but the data is the same: ways with an hypothetical

 Whether you use that joined data to perform Dijkstra stunts or just render

I cannot imagine any more wrong interpretation. ODbL was created just to

with your interpretation you could easily create a private fork: just
extend osm data with tags like

  some hack to pass both nodes' evelations on every way's name
  2) I thought maybe the profile thing in OSRM output would be
  interesting for other devs, so it may be good to code it the clean way
 
  Anyone has an idea how hard it would be to add such a feature inside
  OSRM? Is someone interested in this addition?
 
  Best,
  Yves

   Hello List,
  
   We have elevation data in our source graph. Each vertex has elevation
   information (ele key in OSM-like data). We'd like to have this info
   in OSRM result in order to display profile.
  
   My understanding would be that you need to put this into some tag OSRM
   stores the hsrm file and shows it in the JSON e.g. name.
  
   I do something like the following:
  
 if speed_profile[highway] ~= nil then
   way.speed=speed_profile[highway]
   way.name=table.concat({way.id,highway,way.name,way.ref},|)
 end
  
   So i get way.id, highway type, name and ref ...
  
   What are the chances that elevation data will be available one day in
   the output?
   What do you estimate regarding the complexity to implement it?
   Would a contribution for this feature be considered?
  
   From using elevation data i would expect to have elevation on nodes
   and if adjacent nodes have different elevation, you would need to split
   the way and make it 2 oneways with different costs.
  
   Uphill more expensive than downhill.
  
   Or is it just you'd like to show elevation data in the output?

Re: [OSM-legal-talk] produced work vs. derivative db

 Because, simply speaking, the difference is huge, just like between
 Public Domain (for PW, as long as you contribute OSM) and ODbL (for
 the derivative database, if there is any).
 Bear in mind there's a possibility that there's no underlaying
 derivative database, but PW is made directly from OSM data. 

during the process, there is always a derivative DB, be in only in RAM
or any other form. it does not matter if the process is done in one or
thow shell scripts.

 And other
 PW is based on the first PW...
 I feel the ODbL/PW licence thing is more a dogma than a law, but still
 it should be a well defined dogma :)
 Sincerely,
 
 Tadeusz

 OK thanks. I saw some other email threads on this. I think it is a bit
 arbitrary that access=yes is required isn't it? I mean, why prefer

wrong tag, please don't use access=* at all. it does not take into
account other means of transport. the result is that we have bike routes
where access by bicycles is prohibited (according to osm data and this
stupid tag)

use 
motor_vehicle=*
bicycle=*
...


 to prevent
 routing? I'm not sure of the benefit of this rule, anyway, I'll accept it.
 
 My next question is about tagging routable tracks with access=yes. I
 have done this now, however, how long until I see updates on the OSRM
 map? It seems other people asked for this[1], but the issue was closed
 without a fix. Is there any intention of fixing it?
 
 Let's put it another way, if there is a highway=track without access=yes
 and I'd like to route along that track, is it impossible to get that
 route for at least a few days, except when I do my own build?
 
 I'm just trying to get a decent route along a track with minimal fuss.
 Thanks for your great work by the way!
