Web Maps

There are different tools to render maps on the Web. As far as my hobby projects are concerned, I prefer Leaflet because it is more accessible to the uninitiated and gets things done without much ado. There however are more advanced applications for which OpenLayers would be my choice due to its larger expressive power but with great power comes great complexity. 😉

leaflet-boundary-canvas BoundaryCanvas is a Leaflet plugin for drawing tiled raster layers with arbitrary boundaries.
