Timestamp of latest update
- The map's timestamp is rendered directly in it, and thus cannot be trivially parsed
- The tile generation timestamp, however, is part of the client code
- Parse var timestamp_tiles... line from https://edastro.com/galmap/galmap.js
Map
- Get relevant tiles
  - URL format: https://edastro.b-cdn.net/galmap/tiles/indexedheat/{zoom}/{x}/{y}.png
  - Zoom level 6 is the original size, 1px = 10ly
  - ED to map coordinates:
    - Xm = Xe/10 + 8192
    - Ym = (Ze-25000)/10 - 8192
  - Each tile is 256x256
- Show player position
- Show player route
- Get system discoveries dated after latest update
  - The gap between generating the map and tiles means that any estimations are pessimistic
- Update colors of affected points
