For some time I’ve been looking for a way to display silence on the maps
when I don’t move. I did a test to determine how far the markers must be
apart to make them accessible and how this corresponds with GPS coordinates.
In processing I’ve written a script that looks for the uppermost top-left
coordinate in a file and from that point starts building a grid. Of course
the coordinates aren’t exact but they will around the silent area and you’ll
be able to access all of the points. I build this example using GeoRSS that
I created in Processing.
