Baseline Bob

Initial baseline version

Version 2.0.0 - Geometry-based Street Detection

Major Improvements

🗺️ Geometry-based Detection

• Added GeometryParser.js to parse SVG paths, polygons, and polylines
• Added GeometryCalculator.js for accurate point-to-geometry distance calculations
• Streets and buildings now use proper geometric distance instead of point-based approximations

📍 Fixed Intersection Detection

• Direct SVG element inspection for finding nearby roads
• Correctly identifies intersections like "Yonge and Front"
• North-south streets prioritized in intersection naming
• Increased detection range to 10m for wide streets

🎯 Coordinate Alignment

• Fixed pin positioning with proper tile offset alignment
• Fixed zoom functionality to center on pin location
• Improved pin dragging to follow mouse accurately

🚶 Better Path Filtering

• Separated vehicle roads from pedestrian paths
• Footpaths excluded from intersection announcements
• Cleaner, more relevant location descriptions

🔧 Technical Fixes

• Removed building address fallback for street names
• Fixed map going black on zoom
• Cleaned up debug output for better readability
