Quick update. I tried to hand code the Behrmann projection using a
"Cylindrical_Equal_Area" with a standard parallel of 30 degrees:
String behrmannWKT =
"PROJCS[\"World_Behrmann\"," +
"GEOGCS[\"GCS_WGS_1984\"," +
"DATUM[\"WGS_1984\"," +
"SPHEROID[\"WGS_1984\",6378137,298.257223563]]," +
"PRIMEM[\"Greenwich\",0]," +
"UNIT[\"Degree\",0.017453292519943295]]," +
"PROJECTION[\"Cylindrical_Equal_Area\"]," +
"PARAMETER[\"False_Easting\",0]," +
"PARAMETER[\"False_Northing\",0]," +
"PARAMETER[\"Central_Meridian\",0]," +
"PARAMETER[\"Standard_Parallel_1\",30]," +
"UNIT[\"Meter\",1]," +
"AUTHORITY[\"EPSG\",\"54017\"]]";
CoordinateReferenceSystem crs = CRS.parseWKT(behrmannWKT);
Throws:
org.opengis.referencing.NoSuchIdentifierException: No transform for
classification "Cylindrical_Equal_Area".
Does geotools support any Cylindrical Equal Area Projections?

Subject: Behrmann Projection
Hello- I would like to create a map using the Behrmann Equal Area Projection
(EPSG:54017). GeoTools doesn't seem to like this projection. When I call
CRS.decode("EPSG:54017") I'm getting the following exception:
org.opengis.referencing.FactoryException: Error in "PROJECTION": No transform
for classification "Behrmann".
When I try to pass in a Proj4 style string but I get a different exception.
CRS.decode("+proj=cea +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +datum=WGS84
+ellps=WGS84 +units=m +no_defs")
Throws:
org.opengis.referencing.NoSuchAuthorityCodeException: No authority was defined
for code "+PROJ=CEA +LON_0=0 +LAT_TS=30 +X_0=0 +Y_0=0 +DATUM=WGS84 +ELLPS=WGS84
+UNITS=M +NO_DEFS". Did you forget "AUTHORITY:NUMBER"?
Any suggestions?
Thanks,Peter
