Dear Readers,

I've just hit a problem with one of our datasets and wondered if anybody has
a solution.

We've a dataset of positions of sample values around the North Sea and also
a file of ICES rectangles (various sizes, shapes etc) and now want to
produce maps of average concentration in each ICES rectangle allowing for
the area of each rectangle and also the number surveys undertaken in each
rectangle. This data will then be gridded to produce contours of various
parameters. Any pointers please.


Thanks
