Jeremy Wood is a multidiscipline artist and map maker whose diverse work offers people and places a playground of space and time. In October 2000 he began to explore GPS satellite technology as a tool for digital mark making on water, over land, and in the air. He makes drawings and maps of his movements by recording all his daily journeys with GPS to create a personal cartography. (from the artist’s website)
One of Wood’s projects included a walk though London along the quote: “It is not down in any map; true places never are.” Herman Melville, Moby Dick.
Also from the artist’s website.
The text was written over a period of three months from January 2005. The length of the line recorded on foot for the drawing was 44.2 miles, and the total distance traveled to make the drawing was 458.6 miles. I had two bicycle punctures with reinforced puncture resistant tires, the first of which happened 20 miles into a journey looking for locations that ended in having to push the bike home for 9 miles. After closing the body of the last letter, I headed as far north as the land allowed to a small pier on which the Greenwich Meridian is marked, and finished the drawing by circling around on the footpath at the edge of the River Thames for a full stop.
