Hello,
Steve's raster to vector code is now included in the gt-process module
in GeoTools version 2.6. Parts of the code were rewritten while
porting it to GeoTools so, if possible, could you try switching to
that version and see if you still get the same registration error ?
You will need to include the gt-process jar in your project. The
easiest way to use do the conversion is to use the static
RasterToVectorProcess.process method. Here is the method header:
/**
* A static helper method that can be called directy to run the process.
* <p>
* The process interface is useful for advertising functionality to
* dynamic applications, but for 'hands on' coding this method is much more
* convenient than working via {...@linkplain
org.geotools.process.Process#execute }.
*
* @param cov the input coverage
* @param band the index of the band to be vectorized
* @param bounds bounds of the area (in world coordinates) to
vectorize; if {...@code null}
* the whole coverage
* @param outsideValues a collection of one or more values which
represent 'outside' or no data
* @param progress an optional ProgressListener (may be null)
*
* @return a FeatureCollection containing simple polygon features
*
*/
public static FeatureCollection<SimpleFeatureType,SimpleFeature> process(
GridCoverage2D cov,
int band,
Envelope2D bounds,
Collection<Double> outsideValues,
ProgressListener progress) throws ProcessException {
If you are using maven as your build tool you can simple add
gt-process as a dependency to your project.
You will need to swap over to one of the GeoTools 2.6 releases: the
most recent being 2.6-M3.
Please try it and let me know how it works for you.
Michael
