Examples of org.geotools.process.raster.PolygonExtractionProcess.execute()

Executes the raster to vector process. @param coverage the input grid coverage @param band the coverage band to process; defaults to 0 if {@code null} @param insideEdges whether boundaries between raster regions with data values(ie. not NODATA) should be returned; defaults to {@code true} if {@code null} @param roi optional polygonal {@code Geometry} to define a sub-area within whichvectorizing will be done @param noDataValues optional list of values to treat as NODATA; regions with thesevalues will not be represented in the returned features; if {@code null}, 0 is used as the single NODATA value; ignored if {@code classificationRanges} is provided @param classificationRanges optional list of {@code Range} objects to pre-classifythe input coverage prior to vectorizing; values not included in the list will be treated as NODATA; values in the first {@code Range} are classified to 1, thosein the second {@code Range} to 2 etc. @param progressListener an optional listener @return a feature collection where each feature has a {@code Polygon} ("the_geom")and an attribute "value" with value of the corresponding region in either {@code coverage} or the classified coverage (when {@code classificationRanges}is used) @throws ProcessException
