I fixed it like this:

x = -180.0 + 360.0*RANDOMU(seed, 100) ;Make some random data
y = -90.0 + 180.0*RANDOMU(seed, 100)
z = 1000.0*RANDOMU(seed, 100)

PLOT_3DBOX, x, y, z, $
PSYM = 3, $
XTITLE = 'Longitude', $
XSTYLE = 1, $
XRANGE = [-180.0, 180.0], $
XTICKS = 4, $
XMINOR = 3, $
YTITLE = 'Latitude', $
YSTYLE = 1, $
YRANGE = [-90.0, 90.0], $
YTICKS = 6, $
YMINOR = 3, $
ZTITLE = 'Altitude (hPa)', $
ZSTYLE = 1, $
ZRANGE = [1000.0, 0.0], $
ZTICKS = 5, $
ZMINOR = 2

MAP_SET, /T3D, /CONT, Z = 1000.0, /NOERASE, $
LIMIT = [-90.0, -180.0, 90.0, 180.0], /NOBORDER, $
POSITION = [!X.WINDOW[0], !Y.WINDOW[0], !X.WINDOW[1], !Y.WINDOW[1]]
MAP_CONTINENTS, Z=1000.0, /T3D, /NOCLIP

Continents get clipped for some reason in 3D. Unfortunately,
the MAP_SET command doesn't pass the NOCLIP along to MAP_CONTINENTS,
so you have to call the latter command by itself.

Cheers,

David
