Rob: No, you can't get the whole earth - the most you can get is the cube that fits within it. I can look into adding that functionality for the aeqd projection if there's a real use case. Note that there are other whole-earth projections available (mollweide, vandergrinten, robinson, sinuisoidal etc). These projections have much less distortion far away from the center of the map than the azimuthal equidistant does. Why do you want to use aeqd to plot the whole globe? -Jeff > Thanks, > > Rob > > > John [H2O] wrote: > >> Hello, >> >> I'm creating a web application that will take user input from a javascript >> map to give me bounding coordinates (i.e. urcrnrlat, urcrnrlon, llcrnrlat, >> llcrnrlon) and possibly a switch for polar projection.
