NdviOp missing from graph builder

The NdviOp is available in the Thematic Land Processing drop down menu, but it’s not available in the graph builder. Is this a known bug or is it just an issue with my installation?

Dear gsk33,

Please be informed that the issue related to NdviOp not available in the Graph Builder is known and it will be fixed in coming module updates.
In order to apply NDVI in the Graph Builder you could use the BandMath module.

Best Regards,
Fabrizio

It’s strange that other indices are available but not ndvi

The NDVI Operator was one of the first operators developed. The Graph Builder and the other indices came later. Unfortunately, it is not fully compatible with the Graph Builder. This will be fixed in the future.

It is also simple to implement using band maths in the graph builder and then merging with the other bands.
