Hi, See this gis.stackexchange question about gdal_sieve http://gis.stackexchange.com/questions/227709/why-is-all-0-after-using-gdal-sieve-on-a-raster-layer. By the documentation http://www.gdal.org/gdal_sieve.html it is not clear with which precision the pixels are classified to have the same value. Is it by integers or does sieve handle also floating point numbers?
