Dear Jody,
thanks for pointing me to my mistake, I have changed it to :
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-process</artifactId>
<version>${geotools.version}</version>
</dependency>
and it seems to work.
I have troubles to figure out how to run the code in the test - I tried
using the 2.5-snapshot, as well as the 2.6-SNAPSHOT version, and it
seems like more than the name of the class has changed:
I get offered only the Raster2VectorFactory class, instead of the one
used in the test case - RasterToVectorFactory.
I changed that, but I have no luck with filling the input parameters:
input.put(Raster2VectorFactory.RASTER.key, mycoverage);
for instance. I cannot set these field in the way used in the testcase,
but I can identify them in the process:
Map<String, Parameter<?>> r2vpinfo = (new
Raster2VectorFactory()).getParameterInfo();
Set<Entry<String, Parameter<?>>> set = r2vpinfo.entrySet();
Iterator<Entry<String, Parameter<?>>> iter = set.iterator();
while (iter.hasNext()) {
System.out.println(iter.next().toString());
}
It also seems like the approach used in the UserGuide:
features = Raster2Vector.process( gridCoverage, 2, Collections.EMPTY, null );
does not work - the method process is not offered for Raster2Vector.
I am obviously missing something. What is it? Maybe it is just my lack
of experience with factories/parameters, but so far I have used them for
coverages or shapefiles and all was good.
Thanks heaps,
Martin
