NVDI Raster Subtraction
« on: March 24, 2024, 10:43:47 PM »
Hello
Is it possible to create a workflow that subtracts one NVDI raster from another? I know this is possible in software like Global Mapper but can it be done in Metashape? For example, if I fly a site that has been reclaimed/revegetated with a multispectral system on year 1, and then fly it again on year 2, I would like to be able to subtract year 1 from year 2 to see if there are positive or negative changes to the vegetation at the site.
I see that this type of transform can be done on DEMs already for surface elevations.
Thanks.
