Bands decomposition
8/3/12 11:07 AM
Dear all,
I have asome GeoTIFF products, the product contains two bands, and I want to decompose it to two single GeoTIFF files, which contains only one band.
How to do it batch processing using gpt or command line, or APIs?

With gpt on the command line you need to runs
1gpt Subset -f GeoTIFF -PbandNames=<bandNameOne> -Ssource=<sourceProductPath> -t <targetFile1>
2gpt Subset -f GeoTIFF -PbandNames=<bandNameTwo> -Ssource=<sourceProductPath> -t <targetFile2>


With the API you can do:
 1ProductSubsetDef subsetDef1 = new ProductSubsetDef();
 2subsetDef1.setNodeNames(new String[]{"name_1"});
 3Product p1 = source.createSubset(subsetDef1, source.getName(), source.getDescription());
 4ProductSubsetDef subsetDef2 = new ProductSubsetDef();
 5subsetDef2.setNodeNames(new String[]{"name_2"});
 6Product p2 = source.createSubset(subsetDef2, source.getName(), source.getDescription());
 7
 8ProductIO.writeProduct(p1,new File("file/location/file1.tif"),"GeoTIFF",false, ProgressMonitor.NULL);
 9ProductIO.writeProduct(p2,new File("file/location/file2.tif"),"GeoTIFF",false, ProgressMonitor.NULL);
