This node takes a list of raster file location in the input table and perform masking using a two stage operation where first all of the nodata pixels are set to a rank using the gdal_calc, then polygons are generated using the gdal_polygonize. The input raster files should have numeric name. This process generate output shape files in the desired location. The output table contains the generated shape file locations. It also includes rank as fieldname fieldname in the output shape file.
