## Description
|
|
|
|
<!-- SECTION:DESCRIPTION:BEGIN -->
|
|
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.
