3) The exportMissingValue can be used to replace the missing values by given number to indicate that there is no valid data, this option is required to use the resulting files with ArcGIS as the default setting using 'NaN' to represent missing values is not supported by ArcGIS.
4) The DxDySupported property shown in the above example can be used to export a grid with cells that are not exactly square. The ESRI ASCII grid format definition only supports a single CELLSIZE property that is the same for X and Y axes. If the cell widht and height are not equal and you set the DxDySupported property to true, a DX and DY value will be written, this is conform the GDAL extension to the ASCII grid definition but unfortunately not supported by ArcGIS.
