Hello
my purpose is to get a list of projection systems described in a WKT format (so
using gt-epsg-hsql-2.6.3) ;
and then to use these WKT representations to achieve tranformations using only
the library gt-referencing-2.6.3.jar
to get these WKT strings I use the following code :
CoordinateReferenceSystem crsSrc =
ReferencingFactoryFinder.getCRSAuthorityFactory("EPSG",
null).createCoordinateReferenceSystem(EPSG);
and then crsSrc.toWKT() gives the WKT specification for EPSG
I took 3 WKT representations for respectively EPSG = "EPSG:4326", EPSG =
"EPSG:2056" and EPSG = "EPSG:27572"
then I created for each one a CoordinateOperationFactory object to carry out 2
transformations :
one from 4326 to 2056 (Switzerland) et the other from 4326 to 27572 (France)
using the WKT strings
I noticed that the WGS84 to Swiss transformation is correct,
while the WGS84 to French transformation generates an error saying that
Bursa-Wolf parameters are required ;
I would like to know how to sort out this problem as I need accurate results
and I cannot afford to use the following code involving some transformation
errors:
CRS.findMathTransform(crsSrc, crsDest, true)
is it possible to get Bursa-Wolf parameters in each WKT representation ?
thanks a lot
Jean-Marie
