[gdal-dev] weeding out x,y,z points

[nicholas.g.lawrence at mainroads.qld.gov.au]

A client has a very large (millions of records) ascii file consisting
solely of x,y,z co-ordinates.

They would like to reduce the number of records by weeking out points that
are too close to each other.

Can GDAL or OGR weed out 3D points based on proximity to each other?

Regards,
nick
