Dear colleagues,
I am working on bulk processing of Landsat data using GPT. The following error (…" could not parse expression…" ) is shown when running my script.
In the first node, I calculate three new bands (“dLCC”, “ndvi_master” and “ndvi_slave”) which are used in the second node to calculate a new band (“trend”). Unfortunately, it does not work.
when the graph is ended after the first node, I get a three band product. Opening the new product in SNAP I see all three bands and I can calculate the band „trend“ as shown in my second node. But this is done manually. I will do it automatically.
That’s a bug in SNAP. To give the source products names only works if you have more than one. For a single product simply remove the $input. in your expression.
