    Good question. You're right that Leaflet is great for GPS, but this tool is specifically for robots using SLAM-generated occupancy grids in a local coordinate frame. Even for long-…

    Show HN: I built A GUI for managing waypoints in large-scale robot navigation

    When robot navigation scales from hundreds of meters to several kilometers, managing waypoints as raw numeric values quickly becomes painful and error-prone. This provides a GUI to…

    Thanks for your comment and the great question. Lowpass filtering with downsampling is definitely a more efficient way to simplify images compared to my approach. This project is a…
