Regridding based on other arrays

[Richard Dixon <rdixon@xxxxxxxxxxxxxxxxx>]

Hello again Ferret-Users

Probably another query where the answer is extrememly simple and staring
me in the face. I have some satellite data which comprises three 640x480
arrays:  datavalue, longitude, latitude. Currently I'm just displaying the
data by shadind datavalue and overplotting longitude and latitude.

Is there any straightforward way of regridding the data into a new array
such that the x and y co-ordinates are longitude and latitude (like the
usual NCEP re-analysis data, for example).

Once again thanks for all your help
Richard (still a Ferret amateur!)
