DESCRIPTION:As a mapper\, we spend hours micro-mapping surface types\, tact
 ile paving\, complex building geometries or trees. But when you check the 
 map\, they are invisible.\n\nLegacy web cartography forces a compromise:\n
 **To keep standard Vector Tiles (MVT) small enough for network transfer\, 
 rendering pipelines systematically drop niche tags and simplify geometries
 **.\n\nMapLibre is now the default vector renderer on the OpenStreetMap fr
 ont page. Moving from static rasters to interactive vectors is the next st
 ep in improving this experience.\nTo make the front page a true 1:1 reflec
 tion of the database\, we must eliminate this data-loss.\n\nThis talk cove
 rs the MapLibre technical roadmap for rendering the complete OSM tag dicti
 onary directly in the browser. We detail the integration of two technologi
 es:\n- **MapLibre Tile (MLT)**: A vector data compression specification th
 at reduces bandwidth\, allowing the delivery of heavy\, unfiltered OSM dat
 asets to the client.\n- **WebGPU**: Shifting the computational bottleneck 
 from the CPU to the GPU\, enabling browsers to render massive MLT payloads
 \, dynamic styling\, and 3D geometries at 60fps.\n\nThe presentation featu
 res a live\, split-screen benchmark using dense data to compare the older 
 raster maps vs legacy MVT/WebGL vs the MLT/WebGPU pipeline.\nAttendees wil
 l see how upgrading the shared open-source infrastructure is necessary to 
 visualize **every** mapper’s contribution.
