Last year, after I started geotagging my photos, I did a few visual art projects combining photography and GPS technology. I am fascinated by maps, how we imagine the world around us, how we communicated that world to others, etc.
A GPS receiver (including many smartphone apps) can record a GPS track — that is, a series of linked points recorded at regular intervals or distances as you move. Normally, these tracks are used for navigation — record where you have been so you can later retrace your route and thus find your way back home. These track files are also good for post-adventure analysis. Your can plot your speed, heading, elevation, etc. You can also use the point data in the track to geotag your photos so that you, and others, can see exactly where a particular photo was taken.
Beyond their practical uses, however, GPX tracks, when displayed as a line on a map, have an aesthetic value as well. They are a virtual mark on the land — the mark of an adventurer expressing some desire to explore. In this way they are not unlike the marks an artist makes on paper or canvas. Lines creating shapes, outlining objects, representing barriers overcome or avoided. Lines demarcating space and time. Tracings and recordings of life.
A Walk In The Park
After a long walk at Bowness Park last March, I overlaid photographs I had taken with the abstract and graphically rich tracings of my GPS tracks. Typically, one displays geo-located photos on a map — saying “this is where these photos were taken.”
But the map is not the terrain. The map is not the location.
Instead, I am displaying the map (in the form of the track overlay) on the photo. This gives the photo context. The image exists in concert with — because of — my movement across the land.
The other project I started, is a series of large scale conceptual drawings. By walking a path across the land tracing the shape of a word, I am making visible some thought, some meditative idea. The word — the path — is not visible to others even though it’s creation is a very concrete act. However, by capturing the path in the form of a GPS track, I am able to share the act with others. The track image, is combined with photos taking during the walk so the viewer can experience the original event.
