OK WIndows updates still running so more digging:
Using this code:
CoordinateOperationFactory operationFactory =
ReferencingFactoryFinder.getCoordinateOperationFactory(null);
Set ops =
operationFactory.findOperations(sourceCRS, targetCRS);
for (CoordinateOperation o : ops) {

Have a look at
https://gis.stackexchange.com/questions/313512/specifying-epsg-transformation-method-in-geotools/313523#313523
for
an example.
When you say you added the .gsb to 'org.geotools.referencing.factory.gridshift'
where exactly did you put it?

I was thinking make an app using gt-epsg-hsql jar, and go through hall the
code made available by the factory - and write out their WKT :)

Thanks!
I looked around the EPSG HSQLDB file
https://github.com/geotools/geotools/blob/master/modules/plugin/epsg-hsql/src/main/resources/org/geotools/referencing/factory/epsg/EPSG.zip?raw=true,
but did not figure out an obvious way to dump the data to properties file

Yes, this was intended. The gt-epsg-wkt implementation was intended for use
with Java Applets (which could not create an hsql database locally).
If you must respect axis order you will need to write a script to dump out
the contents of hsql database to a properties file (and replace

Not exactly intended, but
Do exactly what you are doing; and check the user guide for the step to:

That will write out a "prj" file with the definition of latitude/longitude.

I don't remember what the 2.1 API was exactly. It is possible that

Hi Martin, Thank you for your help. However, I cannot find anyway to pass the Hint to the factory like you said, nor can i find CRS class. I am using Geotools 2.1M2. Is your solution for 2.2 instead? Thanks, TrungMartin Desruisseaux <[EMAIL PROTECTED]> wrote: Trung Dinh a écrit :> org.

The source or target CRS probably doesn't contains a "TOWGS84[...]" info. In
such case, Geotools doesn't know how to perform datum change. You can instruct

Hi all, I took Martin's advice, and was able to get the WGS84 (thank you again, Martin). However, when I created the transformation operation, I got an exception: org.opengis.referencing.operation.OperationNotFoundException: Bursa wolf parameters required. Can anybody give me any sugges

Maybe upgrating to Geotools 2.2 would help. If you wish t

1.) I've implemented a coordinate transformation service using GeoTools
2.1 shown in the following code. It converts different CRSs to WGS84_3.
Now, if I want to transform a point from "Gauß-Krüger 31", which is an
Austrian CRS (EPSG:31295) using the Bessel 1841 ellipsoid,
you can add a TOWGS84 as per the example below - hope this helps
