Just so we remember, this is due to gridlines not coastlines:

gmt basemap -R-180/180/-90/-62 -JE0.0/-89.9999/12c -Bafg -BWSen -png map2

Hi, I was just wondering if anything can be done about this? I would like to be able to use gridlines in an azimuthal equidistant projection with generic centre/width, but my example at the moment ends up with horizontal lines all across the map.

You can see clearly the correct gridlines but a huge number of incorrect ones... any idea what the problem is?

Thanks Tom
