I’m liking how my map of walks is turning out. It’s now useful to me in that I can see what streets I’ve walked on and what I haven’t. It’s also sort of pretty. I particularly like how the GPS error gives a random smudge effect to the paths. Transparency for older tracks works nicely. I’ve tried to induce some hue variance just to let the eye pick out individual tracks, but the orange->red scale is a bit lipsticky and seems to demand the question of exactly what hue represents (track length).
