Custom Tile Map (no geo data)

Elastic Stack Kibana
1

Hi,

I have a tileset for a big ingame map (GTA V Example Map Interface) and I want to put it into Kibana. I created the layer and managed to make it display the images, but they are kinda screwed Screenshot

Is it even possible to make the Map feature work with a custom map like this?

And if it somehow works.. how do I set the dimensions for my custom coordinates? I just have x and y with no relation to lat and lng.

Hi @eiksch

The answer is somewhat mixed.

it is possible to use Kibana Maps for this non-geo use-case. For a similar example, see the screenshots where we used Maps to display a map of game-of-thrones (https://www.elastic.co/blog/elastic-maps-7-3-0-released). It does require that all your x-y coordinates are mapped to equivalent lats and lons in the appropriate -90/90 (for lat) and -180/180 (for lon) domains. So this may require a conversion step first on your end.

From the screenshot, it seems you are using the TMS-source. Yes, that's exactly the kind of source to use. So basically, just add https://map.statev.de/{z}/{y}/{x}.png

Unfortunately, why the GTA-map looks screwy in Kibana, is because the orientation of that GTA tile-set is flipped. The orientation of the Y-axis is bottom-to-top for your tile service. Maps only supports the tileset orientations where the Y-axis points top-to-bottom. That is why you get that odd striping effect.

The tileset spec Maps supports is the Google Maps one (https://en.wikipedia.org/wiki/Tiled_web_map). Most toolkits that support cutting up imagery in tileset should support this spec.

I extended my picture now, from 8192x8192 to 16384x8192.

Then I used gdal_translate and created a .tif to add the lat/lon information to the picture

And then I used gdal2tiles to create the tileset.

It now looks like this

@thomasneirynck can you tell me what is missing? It looks like it has something to do with the format of the tileset. Maybe gdal2tiles can't achieve what I need?

edit: it should look like this: link

Eep, that looks worse!

Can you check if the {x}/{y}/{z} parameters are ordered in the URL? it's possible that gdal2tiles puts them in a different order.

btw. you might be interested in this blogpost, that shows a similar use-case. https://www.elastic.co/blog/kibana-and-a-custom-tile-server-for-nhl-data It's a few years old, and does not use the new Kibana Maps, but the principle is the same.
