I need to convert a GeoTIFF image to PNG format with "NoData" pixels in the original image being transparent in the output.

Is there any tool particularly in ArcGIS ArcToolbox or GDAL for this purpose?


In Windows:

for %i in (*.tif) do gdal_translate -of GTIFF -a_nodata 0 %i %~new_ndata.tif
for %i in (*.tif) do gdal_translate -of PNG -scale -co worldfile=yes %i %~cnvt.png

In bash:

for i in *.tif; do gdal_translate -of GTIFF -a_nodata 0 $i $i~new_ndata.tif; done; for i in *~new_ndata.tif; do gdal_translate -of PNG -scale -co worldfile=no $i $i~cnvt.png; done;
