Custom map tile servers (v4)

[Terrance]

Re. v4 migration:

4. Tile Service Configuration Changes

The custom tile configuration has been simplified:

Remove these environment variables:

environment:
  # Remove these lines:
  - CUSTOM_TILES_SERVICE=https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png
  - CUSTOM_TILES_ATTRIBUTION='&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors'

At the moment there is no equivalent for these in Reitti v4.0. If you need this, please open an issue.

For what it's worth, I'd like to continue using my existing map tile server (original request #132), which already caches tiles and serves them to several of my internal services. (Mine serves tiles at https://tile.example.com/osm/{z}/{x}/{y}.png.)

That said, I'm not sure how the TILES_CACHE variable works -- can I just point that at my tile server instead, and not set up reitti-tile-cache? I'm guessing there's an expected URL path that doesn't form part of the variable value?

Hi @Terrance,

Unfortunately, this will get more complicated now.

First, you would need a tile server that serves vector tiles. openfreemap.org is the one I use for tiles.dedicatedcode.com. But this is only the data we use for streets, buildings, water, and so on. Take a look at src/main/resources/static/map/reitti.json. Everything in the datasource block would need an equivalent service. And the old one is also needed at the moment since we switched to the new map only for the main map and the memory page.

So, the idea would be to add a way to replace this JSON with your own.

The reitti-tile-cache is basically an Nginx which caches all these data sources and the old ones.

So, it depends on what you want to achieve. Is it mainly the caching part? Then the tiles-cache is enough. You propably can use your own. Reittis nginx config is in the repo under docker/ Do you want to cut external dependencies or have a strong focus on privacy? We would need to:

• Add a way to use your own style.json in reitti.
• You would need to spin up at least a vector tiles server. We could add switches to enable the terrain and satellite feature into the style.json metadata or spin them up as well.
• then, reitti could use your style.json and this would point to your servers.

Cons:

• way more complicated than in the past
  Pros:
• more features for the map
• with the custom style.json you can customise the whole map rendering. Like no street labels or no streets at all, pink forests, green water whatever. I used maputnik to adjust the styles.

So, long story short:
Sure, I will add this back after we have ironed out the reasoning and what needs to be added to fulfill them.
