I need to check that is there geo-location error or not in the pair of Envisat and ERS-2 30min lag image pair. How would i identify this
You want to check the geo-location error of both sensors? Or do you want to detect if they have an overlap?
yes. if they have an overlap in the image pair of 30 minute lag
In the SNAP Desktop you can have a look at the world map to see if they overlap of course.
When using the JAVA API (or python/snappy) you can do something like this : example.txt (1.1 KB)
But there is no tool for the command line.
