You can just look at html/layers.js, that’s where all the maps are.
It’s based on Openlayers 5.
That’s not necessary, you can actually define a custom tile layer via localStorage in your browser:
- open your local tar1090 page
- open javascript console using F12
- type this:
localStorage['customTiles'] = "https://{a-c}.tile.openstreetmap.org/{z}/{x}/{y}.png"
- after a reload of the page, Custom Tiles layer will be available in the dropdown.
- you want to set that to something localhost obviously.
Yeah that’s your best bet.
I have never done that myself, but it’s definitely the way to go.
