Description
Implement the foundational layer for rendering OpenStreetMap data on the tldraw canvas. This includes coordinate transformation (geographic ↔ canvas), tile rendering as canvas background, and basic interaction patterns.
Core components:
- Geographic coordinate system (lat/lng to canvas x/y transforms)
- OSM tile layer rendering (raster tiles as background)
- Zoom level handling that respects geographic scale
- Pan/zoom gestures that work with map context
- Basic marker/shape placement with geographic coordinates
- Vector tile support for interactive OSM elements
This is the foundation that task-024 (Route Planning) and other spatial features build upon.
Acceptance Criteria
- #1 OSM raster tiles render as canvas background layer
- #2 Coordinate transformation functions (geo ↔ canvas) working accurately
- #3 Zoom levels map to appropriate tile zoom levels
- #4 Pan/zoom gestures work smoothly with tile loading
- #5 Shapes can be placed with lat/lng coordinates
- #6 Basic MapLibre GL or Leaflet integration pattern established
