WMS-V - Video Map Tiles for the 3rd or 4th Dimension
summary
Proposes replacing hundreds of PNG tile requests with continuous video tiles to show temporal raster data, demonstrating a proof‑of‑concept for a national post model and Himawari satellite imagery (10‑minute frames, 1080p). Implementation uses 110 image requests as the pain point and moves to HTML5 video + canvas/WebGL for hardware‑accelerated decoding and client‑side filtering. Server-side workflows use ffmpeg server-side composing with hybrid caching, double buffering and frame caching; synchronization, transparency and browser stability remain the main limitations while dynamic on‑the‑fly encoding increases server load.
