Architecture

🗺️

Full Apollo Element Support

Draw lanes, junctions, crosswalks, signals, stop signs, speed bumps, clear areas, and parking spaces. All elements serialize to valid Apollo protobuf.

📐

Real-time Geometry

Lane boundaries are computed instantly using turf.js offset. Width, boundary type, and style update live as you edit properties.

📦

Accurate Binary Export

Produces all three Apollo .bin files. The sim_map downsampler and routing graph cost formulas are direct ports of the Apollo C++ source.

🔄

Round-trip Import

Load an existing base_map.bin, edit it, and re-export. The decoder restores all lane topology, geometry, and element relationships.

Undo / Redo

Full edit history powered by Zustand temporal middleware. Every map mutation is reversible.
