A drawing made from dots

I read an article at The Register about a Swede called Erik Nordenankar who decided to “paint” the world’s largest painting by packing a GPS in a suitcase and tracking where it goes then download the data and let the computer show the track with a line. Thus, by sending the bag in a creative way he’ll end up with a self portrait of GPS tracks.

Is this the same GPS technology that already has problems indoors of very many buildings? The GPS system that I bet will have a very hard time to function when flown around inside the luggage compartment of a modern jet airplane? I have a feeling that drawing will mostly be a lot of dots to draw lines between…

According to the article, this is a publicity stunt made by DHL.
