Hi Tony, By default, Ferret plots along a linear scaling of longitude and latitude. There is also a ferret jnl script for plotting in Plate Caree projection which is also x=longitude, y=latitude. It is called mp_plate_caree.jnl See Ch6 Sec10.4. Map Projections in the Ferret User's Guide for more info. http://www.ferret.noaa.gov/Ferret/Documentation/ Joe -------------------------------- Tony Jolibois wrote: Hi all, |
