Missing Sprite images? #1345

Open markdavieswlt opened 1 month ago

markdavieswlt commented 1 month ago

I've used the docker installation to load the tileserver which works well, and I can view the maps etc

docker run --rm -it -v /docker-sets/maps:/data -p 8080:8080 maptiler/tileserver-gl --file planet.mbtiles --verbose

But when I view the developer toolbar, I see lots of "missing" errors in the console window

i.e. when loading the URL :8080/styles/osm-bright/#17.23/-34.103519/18.81684

I get around 10 "missing" messages:

util.ts:267 Image "gate_11" could not be loaded. Please make sure you have added the image with map.addImage() or a "sprite" property in your style. You can provide missing images by listening for the "styleimagemissing" map event.

Is this a problem with the docker command, or something I've missed?

That error in the console doesn't necessarily indicate an issue, bit it does mean there is no matching sprite found that your style asked for. You could have a working sprite sheet an not have every spite the style asks for.

For example, osm-bright only includes these icons https://github.com/openmaptiles/osm-bright-gl-style/tree/master/icons if you look at sprites.json in the release there is no "gate_11" in there.

However the reason you see that warning, is because in style.json there is something like this layer "poi-level-3", which asks for icons like "icon-image": "{class}_11", notice it is using the class for the name of the icon, but in your example, the class would be 'gate', which doesn't exist in the given sprites.

In my own project I ended up trying to add a lot of those missing icons https://github.com/acalcutt/icon-fonts , which look like https://github.com/acalcutt/wifidb-tileserver-gl/blob/master/tileserver-gl/styles/WDB_OSM/sprite.json#L979 https://github.com/acalcutt/wifidb-tileserver-gl/blob/master/tileserver-gl/styles/WDB_OSM/sprite.png

Thanks I'm actually using osm-liberty, and it has the same issue, As that isn't included in the default docker setup, I used the osm-bright example

Does anyone know if there is are definitive sprite json/png files I can use that will show everything requested?

Not that I am aware of. My sprites probably come the closest because I actually tried to add all the icons that I saw were missing in the console errors you mentioned.
