 </span></blockquote>We have a similar group in the UK. The UK National Grid system consists of 100km squares, within which coordinates are defined by &quot;easting&quot; and &quot;northing&quot; figures, usually to 3-digit (=100m accuracy), or by GPS 5-digit (=1m) accuracy. The squares themselves have unique digraph identifiers. A (small) group of people have developed an interest in seeking out all land-based points with coordinates 00000 00000. And standing on them, obviously.<br/>
