Any maths buffs?

fuck yeh, cheers, that saved me a load of time!

persevere with matlab. it's a great tool.
you need to sort your data into 3x 2d vectors (lat, long, temp)
use
axesm('mercator')
pcolorm(lat,long,temp);
demcmap(temp);

can't test this as i no longer have a license - check here for more details about pcolorm
