Edit metadata

Hi
How can I edit metadata manually?

Hi,

simply speaking, this is not supported.
You can save the product as BEAM-DIMAP ad edit the xml content of the *.dim file. This would be a workaround.
What is your use case? Why do you want to change the metadata?

Thanks for your reply. I want to geocode Agrisar simulated sentinel 1 SLC images. These images have incorrect metadata. In other words latitudes for first/last near are switched by first/last far values. I geocoded images and exported as google earth kmz and found this problem.
