Description

RasterToVectorProcess sets the values associated with each generated polygon to those of a representative cell from the source grid coverage. The cell is chosen using the JTS InteriorPointArea class, however it seems that this can lead to an incorrect point being selected in some cases, such as when the polygon is a doughnut.
