Using view1090-fa without internet

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.
