Sketch Map is a clever interactive map which uses D3.js together with Walkway.js to sketch a route map 1 lilliputian fleck at a time. Zoom inwards together with out on the map or pan or thence together with you lot tin discovery how the roads together with transit lines are sketched out inwards real-time.
When I start saw the map inwards activity my initial thoughts were '... this is really clever. Not really useful ... merely really clever'. However, thinking nigh this a lilliputian more, I tin run across some possible uses for this. You could maybe role the animated drawing part to animate the drawing of a route on altitude of a map.
You could besides role this technique to add together dissimilar layers to a map. For example, you lot could plough over users the alternative to add together edifice footprints to a basic route map. When this alternative is selected you lot could together with thence sketch the footprints onto the map using the sketchcart technique.
If you lot desire to bring a play or thence amongst this yourself the code for Sketchcart is available nether an MIT license on Github.
