Annelogue points me back to a project I read about in Wired some months ago. The disussion at her site suggests ways to place the Yellow Arrows geographically.
I just installed a small program on my Nokia 6630 mobile called CellSpotting. It works like this:
Your mobile is always connected to a mobile transmitter somewhere. These transmitters have unique ID’s and are called Cells. By reading what Cell you are connected to and do a lookup in a database on that particular cell, your location can be roughly determined (I think at a level of detail down to a couple of hundred meters).
With CellSpotting installed on your mobile you can always hit a “Go cellspotting” button. What it does is that it makes note of the cell you are connected to and do a lookup in a database on the web. If someone has spotted that cell already and submitted a description you will recieve that description. It could be anything. Info on nearby points of interest or simply a greeting. If the cell is “undiscovered” you can fill in info on the cell yourself. Anyone visiting that cell after you will get your info if they hit “Go CellSpotting” in the cellspotting application.
Now, if the people behind the CellSpotting program could enhance it with the following two features:
1. A possibility to let people snap a picture with their phone and add to the description of a cell
Would be great fun to be able to look up pictures of the surroundings where you are. Both because it would help you decide if the walk to the park described would be worth it and because having pictures from the actual spot you are, from different seasons and different points of time could be interesting in its own way.
2. A possibility to record the latitude and longitude and add it to your spot if you have a GPS connected to your phone
3. Some kind of possibility to send a mail from your phone with the cell and a link to the description in the CellSpotting database. Would be great information to add when moblogging
….anyway. CellSpotting is kind of Yellow Arrows… without the arrows.
