Frank Jacobs over at Strange Maps has found another “out in leftfield” map. This cartographic invention is courtesy of an artist who “paints” using his GPS-enabled bicycle.

GPS technology is opening up exciting new hybrid forms of mapping and art. Or in this case: cycling, mapping and art. The maps on this page are the product of Michael Wallace, a Baltimore-based artist who uses his bike as a paintbrush, and the city as his canvas.

As Wallace traces shapes and forms across Baltimore’s street grid, the GPS technology that tracks this movements fixes the fluid pattern of his pedalstrokes onto a map. The results are what Wallace calls GPX images, or ‘virtual geoglyphs’ [1].

These massive images, created over by now three riding seasons, “continue to generate happiness, fitness and imagination through planning the physical activity of ‘digital spray-painting’ my ‘local canvas’ with the help of tracking satellites 12,500 miles above.”

Wallace’s portfolio by now is filled with dozens of GPX images, ranging from pictures of a toilet to the Titanic. They even include a map of the US – traced on the map of Baltimore. How’s that for self-reference? Or for Bawlmer [2] hubris?
