Is it possible to use the Goode Homolosine projection in QGIS? Both QGIS and GRASS seem to have trouble with the interruptions, squashing the higher latitudes together. I tried +proj=goode +ellps=sphere +datum=wgs84 as a custom CRS.
There has been a question on interrupted projections before: Discontinous or Interrupted map projections?
The conclusion was that proj4 (which is used for projection handling in QGIS and GRASS) does not support interrupted projections.
With QGIS Lisboa, there is now a basic support for Goode Homolosine projection.
I downloaded IGH data from http://edc2.usgs.gov/glcc/fao/data_specifications.php
and set up this user CRS:
for North America.
lon_0 and x_0 are from Appendix 03 of this document: http://proceedings.esri.com/library/userconf/proc98/proceed/TO850/PAP844/P844.HTM
Overlaying natural Earth world boundaries_m, I get this picture:
Fitting good in North America (about 20km misplaced), and distorted in other regions.
Just noticed that proj knows interrupted goode homolosine by now:
gives me this picture of Natural Earths world boundaries and a 10-degree-vector grid:
I'm not sure which parameteres apart from
