GPS Drawing, also known as GPS Art and Strava Art, is a method of drawing where an uses a Global Positioning System (GPS) device and follows a pre planned route to create a large-scale picture or text on a map. Artists usually run or cycle the route though cars, vans, and aeroplanes are used to create larger pieces.
GPS artists can spend many hours finding a certain image or text hidden in a map or can sometimes simply see an existing image in a map due to Pareidolia. In many cities and towns the road layout and landscape restricts the routes available so artisst have to find creative ways to show their pictures or characters. In cities where there is a strong grid pattern an 8-bit style or pixelated images can be created of almost any object or shape. Many artists will create paper or digital maps of their route to follow on their journey.
There are many approaches to GPS Drawing which an artist can choose depending or their means of travel and the landscape around them.
Roads, Trails, and Paths Only
This style uses only pre existing roads, paths, trails, etc. which can make it more challenging to find a route and plan the artwork. On the other hand following these paths makes navigation during the journey much easier and the artwork is more likely to reflect the original plan. This is how the majority of GPS artworks are made.
Freehand on Open Ground or in Open Air
Freehand GPS drawing is where artist creates a shape on open ground without following existing paths which means the artist has to watch their progress in real time on their GPS device. Artists can run or cycle over open ground such as parks, fields, and car parks. Artists in cars and other motor vehicles can draw shapes on large open areas such as deserts, airfields, and beaches. Almost all artworks created by aircraft and watercraft use this technique as they are not restricted by human and physical geography. Freehand GPS drawing opens unlimited possibilities but without waypoints and existing routes it is very easy to loose track of your progress and make mistakes.
Pausing the GPS Device
By pausing the GPS device and restarting it at different locations an artist is able to draw straight lines across the map though the built environment and over physical barriers. Though this can create very striking images and open up new possibilities in a city most artists do not use technique.
Adding Extra Images
Some artists add extra images or lines to the map after they have created the route. They can do this to simply add googly eyes to an animal or face or go further add lines and other features which help viewers see what they have drawn. Other times an artist will show a photo or other image alongside their drawing if it is not clear at first glance what has been drawn.
Most people use a route mapping app or other service to display their drawing online and to share on social media. Popular apps include Strava, Map My Run, and Garmin. Many artists also import their route into Google Maps, Open Streetmap, Viweranger, and other map services before capturing the image to display and share. This gives the artist the option of expanding and cropping the image, orienting it another way, or tilting the map to add perspective. Some artists use false color maps then choose contrasting colors for their route to create vivid images.
Examples and Artists
The idea was first implemented by artists Hugh Pryor and Jeremy Wood, whose work includes a 13-mile wide fish in Oxfordshire, spiders with legs 21 miles long in Port Meadow, Oxford, and "the world's biggest 'IF'": a pair of letters, "I", which goes from Iffley in Oxford to Southampton and back, and "F" which traverses through the Ifield Road in London down to Iford, East Sussex, through Iford and back up through Ifold in West Sussex. The total length is 537 km, and the height of the drawing in typographic units is 319,334,400 points. Typical computer fonts at standard resolutions are between 8 and 12 points.
In early 2014 programmer Joe Rosen released a GPS-A-Sketch GPS sketching app for iOS, through the iTunes App Store.
One of the most prolific GPS artists is the artist known as WalleyGPX who, as of October 2018, has created over 500 pieces of GPS art. He uses pencil and paper to plan the routes around his home city of Baltimore which he then creates by bicycle.
