expressible as string of cell codes
(labels) e.g. 3013497311146831114783111479
3111488311148931114993112122 311212331
121313112132 (etc.)
can send to custom mapper to generate map
on-the-fly
gridded representation alone

spatial searching is then a text match process,
e.g. does 3111489 (or 31114) occur in
the text string 30134973111468311147831114
793111488311148931114993112122 31121233
1121313112132 (etc.)

The matching mechanism can be hidden from the
user, e.g. providing a point-and-click interface
7
if c-squares references are explicit in
www-displayed metadata, a standard search engine
can even be used to do the spatial searching
