Hi, I'm trying to convert WGS84 lat/lon points to NTF Lambert II (EPSG:27572) points.
The following code crashes for an unknown reason :
--------------------------------------------------------------------------------------
MathTransform transform = null;
try {
CoordinateReferenceSystem sourceCRS = DefaultGeographicCRS.WGS84;
CoordinateReferenceSystem targetCRS = CRS.decode("EPSG:27572");
transform = CRS.findMathTransform(sourceCRS, targetCRS, true);
} catch (NoSuchAuthorityCodeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FactoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
--------------------------------------------------------------------------------------
The stacktrace is the following :
--------------------------------------------------------------------------------------
org.opengis.referencing.FactoryException: Error in "TOWGS84": Can't

because "-" is unrecognized.

It seems to be a parsing problem :
Error in "TOWGS84": Can't parse
"-168,-60,320,0,0,0,0],AUTHORITY["EPSG","6807"]],PRIMEM["Paris",2.33722917,AUTHORITY["EPSG","8903
(...)
false_northing",2200000],UNIT["metre",1,AUTHORITY["EPSG","9001"]],AUTHORITY["EPSG","27572"]]"
because "-" is unrecognized.
I am using geotools 2.5.1 on a Debian system. I have tested with the Sun
JVM 6 and the openjdk with the same output. The epsg reference is from
gt-epsg-wkt-2.5.1.jar.
The locale of the system is en_US.
I have tried to parse a text string containing "-168" using the same
options as in the AbstractParser.java class without any problem.
Any idea on the problem would very helpful. I can provide more info if
needed.
Thanks in advance,
Didrik
