gpt BandMaths and multiple source products
3/30/12 3:23 PM
Hi,

How should the multiple source products be specified in the graph xml to reference the different products with sourceProducts#.bandName in the BandMaths operator as described here

I'm calling the graph with:

gpt mygraph.xml -SfirstProd=xxx.dim -SsecondProd=yyy.dim -t out.dim

and would like to compute a new band using bands from both of the sources.

Hi Thomas

I attached a simple graph and here's the command & error message.

Hi Mikko,

your expression in the XML-file is missing the '$'-characters.
It should be $sourceProducts0.cloud_prob + $sourceProducts1.c2r_tsm instead of sourceProducts0.cloud_prob + sourceProducts1.c2r_tsm.

The rest of your configuration is fine.

Best regards,
Thomas
