Bus and metro stations not showing up? #337
Comments
Ah, I see. Try building #338 and see if that makes it better. |
I'm on Windows so that will be difficult... |
You don't need to build tilemaker itself, it's just a change to the .lua file. If you change the process-openmaptiles.lua file to have that fix, then rerun tilemaker, it should (fingers crossed) work for you. |
Seems to be working! Thank you! |
Excellent! |
OK, on further investigation it seems that only the bus stations are visible. No metro or tram stations. Is this possible? |
Certainly possible. Could you give me an example of a metro or tram station that you'd like to see included, with its OSM object link (so that I don't have to go scratting through the impenetrable OSM wiki public transport documentation)? |

Can you give me an OSM object link, please. For example, https://www.openstreetmap.org/node/123456 |
That is bizarre, cause the tram icons I can see on the maputnik link aren't visible on the openstreet map! OSM only shows bus stops... |
Switch to the transport layer or OPNVKarte on osm.org; find the tram stop; use the "Query features" tool to click on it; select the one you want; send the OSM object link like https://www.openstreetmap.org/node/123456 . |
These are examples of a tram stop: And of a railway station: |
bfe1bb9 should fix this - it now generates POIs like this:
(output from |
So this should work, right? Hmmm... it's not...
|
Don't know, I'm afraid - debugging styles is a bit outside tilemaker's scope ;) I'd recommend using |
Could you give the exact command line that you're using, and link to the .osm.pbf extract? |
tilemaker --input belgium-latest.osm.pbf --output=tiles/ --process process-openmaptiles.lua --config config-openmaptiles.json Source of the PBF is from geofabrik. Extract ends with "Sorting nodes" and returns to the command prompt. I've retried it with the original lua script and it's failing as well. I've recently installed Windows 11 on my laptop, might be due to that? |
I don't have any experience with Windows but it's possible that you might have run out of RAM, especially if Windows 11 itself takes up more RAM than your previous version. If you have an SSD, running with I'll run a quick check here on the Belgium extract (on Linux) to see if I can reproduce the issue. |
--store didn't help, still exits right after "Sorting nodes". UPDATE: found the issue, with the original LUA script everything works again, so there must be a mistake in there somewhere... Might be an interesting idea to show an error message in the future instead of exiting back to the command prompt :-) |
Ah, that's worth knowing. It does usually output a message on Linux/macOS so maybe that's a Windows executable thing. Glad it's working anyway :) |
This PR generalizes the idea of `node_keys`, adds `way_keys`, and fixes systemed#402. I'm not too sure if this is generally useful - it's useful for one of my use cases, and I see someone asking about it in systemed#190 and, elsewhere, in onthegomap/planetiler#99 If you feel it complicates the maintainer story too much, please reject. The goal is to reduce memory usage for users doing thematic extracts by not indexing nodes that are only used by uninteresting ways. For example, North America has ~1.8B nodes, needing 9.7GB of RAM for its node store. By contrast, if your interest is only to build a railway map, you require only ~8M nodes, needing 70MB of RAM. Or, to build a map of national/provincial parks, 12M nodes and ~120MB of RAM. Currently, a user can achieve this by pre-filtering their PBF using osmium-tool. If you know exactly what you want, this is a good long-term solution. But if you're me, flailing about in the OSM data model, it's convenient to be able to tweak something in the Lua script and observe the results without having to re-filter the PBF and update your tilemaker command to use the new PBF. Sample use cases: ```lua -- Building a map without building polygons, ~ excludes ways whose -- only tags are matched by the filter. way_keys = {"~building"} ``` ```lua -- Building a railway map way_keys = {"railway"} ``` ```lua -- Building a map of major roads way_keys = {"highway=motorway", "highway=trunk", "highway=primary", "highway=secondary"}` ``` Nodes used in ways which are used in relations (as identified by `relation_scan_function`) will always be indexed, regardless of `node_keys` and `way_keys` settings that might exclude them. A concrete example, given a Lua script like: ```lua function way_function() if Find("railway") ~= "" then Layer("lines", false) end end ``` it takes 13GB of RAM and 100 seconds to process North America. If you add: ```lua way_keys = {"railway"} ``` It takes 2GB of RAM and 47 seconds. Notes: 1. This is based on `lua-interop-3`, as it interacts with files that are changed by that. I can rebase against master after lua-interop-3 is merged. 2. The names `node_keys` and `way_keys` are perhaps out of date, as they can now express conditions on the values of tags in addition to their keys. Leaving them as-is is nice, as it's not a breaking change. But if breaking changes are OK, maybe these should be `node_filters` and `way_filters` ? 3. Maybe the value for `node_keys` in the OMT profile should be expressed in terms of a negation, e.g. `node_keys = {"~created_by"}`? This would avoid issues like systemed#337

This also adds a SIGUSR1 handler during OSM processing, which prints the ID of the object currently being processed. This is helpful for tracking down slow geometries.
I'm not able to show public transport stations on my map. POI's like hospitals, parkings and shops appear, but no stations or bus stops.
My layout json uses the "poi" source layer with a filter on "bus", "rail","airport".
Is Tilemaker using an alternative name for the transportation layer? Or does it currently skip those points while making the vector layers?
