[mkgmap-dev] Public transport

Sun Feb 1 12:07:53 GMT 2015

I posted to the list last April http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2014q2/020800.html and there was no response. It seems that, although the post appeared on the mkgmap web site, most subscribers did not receive it because of the Yahoo! problem http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2014q4/022204.html

Therefore I am reposting the message, updated as necessary:

I have entered some public transport data into OSM. I have made every effort to enter the data in accordance with the new public transport schema. Some 'old' tags are also present because I started mapping the data before the new schema was approved. For testing purposes I used the extract from Geofabrik of the Languedoc-Roussillon region of France. I used r3433 with the default style and these options: --max-jobs --code-page=1252 --add-pois-to-areas --route --link-pois-to-ways --precomp-sea=sea-20150123211701.zip --generate-sea --index --bounds=bounds_20150129.zip --location-autofill:bounds,is_in,nearest --housenumbers. Looking at the results, I noticed a number of things.

(1) Names of railway stations

The names of many railway stations appear in the form SNCF: Agde.
https://www.openstreetmap.org/way/72614628
This is the result of generic processing of names in the style file inc/name. There are about 3500 railway stations in France and more than half of them are tagged operator=SNCF. I would prefer to see the name in the form Agde SNCF, which was produced by earlier versions of the default style, before the file inc/name was introduced. This is more convenient for searching on a device.

(2) Names of bus stops

This is an example of the name of a bus stop as it appears in the generated map: Agglo Hérault Méditerranée: (1;2;3;4;5,4,4,3,3)(1;2;3;4;5,4,4,3,3)++ Gare SNCF
https://www.openstreetmap.org/node/1424432523
The Garmin software and the device will only display the first part of the string. I used QLandkarte GT to see the complete string. (For legibility, I have used lower case in the strings, although they are in upper case in the generated map.)

Earlier versions of the default style produced the result Gare SNCF (1;2;3;4;5,4,4,3,3)+Agglo Hérault Méditerranée, which I prefer. "Gare SNCF" is the name of the bus stop. The earlier version would be essential, to allow you to see the name of the bus stop on a device. What do others think?

The solution which I use for my own maps, is as follows. Before line 16 of file inc/name
ref=* & (operator!=* & brand!=*) { name '${ref} ${name}' | '${ref}' }
insert this line
ref=* & (operator!=* & brand!=*) & (highway=bus_stop | railway=tram_stop | railway=halt | railway=station) { name '${name} ${ref}' | '${ref}' }
Before line 27 of file inc/name
operator=* & brand!=* {
insert these 6 lines
operator=* & brand!=* & (highway=bus_stop | railway=tram_stop | railway=halt | railway=station) {
 name '${name} ${ref} ${operator}' |
      '${name} ${operator}' |
      '${ref} ${operator}' |
      '${operator}'
}

The text 1;2;3;4;5,4,4,3,3 can be changed to 1;2;3;4;5 by using the new not-contained filter as proposed in another thread.

The doubling-up of the route_ref and the shelter indicator (+, - or *) is a bug. I will address this in a separate thread.

I will leave a further question about public transport for another thread.
