There was a great answer to Google Earth Engine Reprojection to non-EPSG defined CRS about the support of Interrupted Goode Homolosine projection in GEE.

It seems that since release 22.3 the Homolosine projection is now available in GeoTools. However when I try in Google Earth Engine I get the error Projection: The CRS of a map projection could not be parsed. No problems with Mollweide.

The code I am running is here.

// Get a sample image (Landsat 8) which uses a UTM projection.
var image = ee.Image('LANDSAT/LC08/C01/T1_TOA/LC08_044034_20170614');

// Get the bounding coordinates of the Landsat image.
var bounds = image.geometry().bounds().getInfo()['coordinates'];

print('Original image (UTM) URL:',
    bands: ['B4', 'B3', 'B2'],
    min: 0,
    max: 0.3,
    dimensions: '400'

// Project the image to Mollweide.
var wkt = ' \
  PROJCS["World_Mollweide", \
    GEOGCS["GCS_WGS_1984", \
      DATUM["WGS_1984", \

var proj_mollweide = ee.Projection(wkt);
var image_mollweide = image.reproject({
  crs: proj_mollweide,

var proj_igh = ee.Projection(igh);
var image_igh = image.reproject({
  crs: proj_igh,
  scale: 300

Is the GeoTool version used in GEE less recent than the one integrating this projection?

If you have a need for this projection, you can request it at Google Earth Engine's issue tracker. Please make sure to describe how it would be useful to you; it would also be useful to mention that it is available in newer GeoTools.
