DESCRIPTION:How do you deliver smooth\, detailed mapping to millions of pas
 sengers aboard French TGV trains while working within tight storage and se
 rver resource constraints? This talk traces the journey of renewing the ma
 pping system for the WiFi portal on board the TGV fleet (700 train sets).\
 n\nWe will explain our choice of PMTiles technology to move to vector tile
 s without relying on a heavy cartographic server. We will share our resear
 ch into data size optimization — from studying the impact of building fo
 otprints to managing zoom levels — and walk through the trade-offs requi
 red to ship a complete European base map on board. Finally\, we will cover
  the specific work done on railway data (routes\, diversion paths) and the
  custom design created to give passengers an immersive experience at 300 k
 m/h.
