Re: [OSM-dev] Questions on modifying openstreetmap-carto
"reading from relation" part is quite hard. I have no idea how to do that.

Re: [OSM-dev] Questions on modifying openstreetmap-carto
Hello again, I am starting to get the basics of adding new fields to project.mml, but I now wish to update “amenity-points” so that bus stops use the network name from the “stop_area”, like they do in France. At the moment I can manage: tags->'network' AS network, … which calls up the network tag from the node only. How do I make it to read from the “stop_area” relation too? Apologies for being very specific: I am very new to anything beyond simple recolours. — ika-chan! > On 25 Aug 2020, at 21:44, Andy Townsend wrote: > > On 25/08/2020 19:52, Mateusz Konieczny via dev wrote: >> Yes, I always used normal text editor. >> > Same here.

There are projects such as https://wiki.openstreetmap.org/wiki/TileMill which were / are designed to automate map reloading after changes, but when I last used TileMill (a long time ago) there were signnificant problems using TileMill with an OSM Carto-derived style (not least - there are so many tabs that they disappeared off the screen). I tend to just reload when I want to rerender. When changing my own OSM Carto-derived map style I use https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/update_render.sh and https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/update_carto.sh to reload data (the first if a lua script has changed and the database needs to be reloaded; the second if only a style file has changed and the style just needs to be recompiled). If you want to see how changes are done I would recommend looking at pull requests and commit history. I tried to summarise "Adding a change to OSM Carto" at https://www.openstreetmap.org/user/SomeoneElse/diary/43041 ; some of that won't be relevant but some of it might still be - things like testing the effect of a colour change. If you haven't seen it already, please do read https://ircama.github.io/osm-carto-tutorials/git-workflow/ and the related tutorials there - they're excellent!

Yes, I always used normal text editor. If you want to see how changes are done I would recommend looking at pull requests and commit history. 25 Aug 2020, 18:53 by mapper+...@minoa.li: > Hello, > > I have made significant progress in creating a tutorial for a fantasy map > server on the wiki, having gone as far as getting Nominatim and its UI > working last night. > > Now, I am moving my focus to modding OpenStreetMap Carto, and I know a few > very basic modifications, like recolouring existing features (see > https://wiki.openstreetmap.org/wiki/User:Ika-chan!/British_road_colours). > However, I would like to expand on mere recolouring and ask how I can modify > OpenStreetMap Carto to: > > 1.
