If the interupted version of Goode is used then *NO* standard version of
[l]proj will handle it without the user segmenting the data into the
subregions of the interuptions.
A closer examination of jpeg does seem to verify the idea of an interrupted
As an aside, for the America continents segment: +lon_0=-100. In addition,
one needs the appropriate +x_0=-1.745329 for unit sphere (multiply that value
by the radius used to get a proper value for this case). These values apply
for Goode's land map.
In addition, because of the wide variation of segmentation used, it is not
likely that a proj inverse for segmented projections will be an integral part
of the basic software.
