Could you build this?
Partial While mapping libraries make the frontend manageable, aggregating, partitioning, and smoothly animating 291 million historical geospatial trip trajectories in the browser demands serious big-data pipelines and GPU optimization.
What it would actually take: The build requires an offline batch processing pipeline (using Apache Sedona, DuckDB, or ClickHouse) to compress 291M GPS paths into custom spatiotemporal binary tiles (e.g., FlatGeobuf or Mapbox Vector Tiles). The client needs Deck.gl or custom WebGL/WebGPU shaders to handle timeline playback and GPU-accelerated spatial indexing at 60 FPS without crashing browser memory.

Same idea, different domain
Nobody's really built a analytics & bi tool for Legal yet.
