i'm working with HUGE arrays. we use a simrad ek500 echosounder
with 3 seperate frequencies, so i am getting 3 650 floating-point
arrays per second. i go out to sea and collect data 6 weeks a year,
so i end up with gb's and gb's of data. i was able to make a program
that allows you to interactly view weeks of data at once (using rebin
and congrid). the tough part was making a surface that had the x-y-z
axis as lng,lat,depth, where the boat traveled (with cutoffs at the
ocean depth) and then pasting the acoustic data onto the surface. (i
know this sounds easy.. but this wasnt a simple surface and image
problem. it is tough to explain without visuals, but you can check
out http://www.nefsc.noaa.gov/femad/ecosurvey/acoustics/ if you really
want to understand our data.)

rick - do you know Mike Jech?
david - i can understand your jealosy, but no need to be envious, we
can't all have big computers :) you might want to check out
