thanks Jody for your suggestion
at present, I just need a dozen of WKT strings but I already notice that,
sometimes , it is hard to find the Bursa-Wolf parameters ;
as I told you is that I must use a light library (gt-referencing-2.6.3.jar)
for example if I consider Spain mainland the corresponding EPSG code is 2062
and there is no TOWGS84 parameters in the WKT string ;
http://spatialreference.org/ref/epsg/2062/ doesn't specify any TOWGS84[..]
string as well
as Geotools requires Bursa-Wolf parameters to work (when using just
gt-referencing-2.6.3.jar), is there an official site providing them ?
if they are not required, is there a "trick" to set TOWGS84[..] to default
values ?
note : even when using gt-epsg-hsql-2.6.3.jar I have an error at :
op = coFactory.createOperation(crsSrc, crsDest); // crsSrc created from the WKT
string (4326), crsDest created from the WKT string (2062)
saying that Bursa-Wolf parameters are required...
I have another remark regarding the WKT format :
if I use the OGC wkt definitions given by the site spatialreference.org with
Geotools, none of them works fine (at least those I tried) ;
the results are wrong (even if I invert latitude and longitude...)
does it mean that the WKT format depends on the tools that processes it ?
thanks
Jean-Marie
