Commercial use of images created by pygmt and its underlying DCW data

Is commercial use permitted of images derived from images generated by pygmt, GMT, and its underlying DCW data? e.g. Can I put these images on a puzzle, mug, sweatshirt, etc, and sell the product?

Yes. It’s all free softs/data.

Yes, you can do that. Our license only restricts distribution of GMT source and the data sets themselves, not graphics representation of them.
