Hi, I’ve noticed that when I use `gmt spatial -Q[unit]`, it seems to give me the area in km^2 (I think?) no matter what unit I choose. I’m wondering what the expected behaviour is supposed to be? If I use `gmt spatial -Qd`, I’m not sure I should expect an answer in degrees squared, should I? ```auto cat << EOF > poly.tmp 0 0 0 1 1 1 1 0 0 0 EOF gmt spatial poly.tmp -Q gmt spatial poly.tmp -Qk gmt spatial poly.tmp -Qe gmt spatial poly.tmp -Qd ``` Gives the results ```auto 0.5 0.5 1 0.5 0.50000702007 12281.2810988 0.5 0.50000702007 12281.2810988 0.5 0.50000702007 12281.2810988 ``` I’m using gmt v6.2.0. Is this expected? ---

Hi tmerry. Yes, you are right. It is a [bug](https://github.com/GenericMappingTools/gmt/pull/6060) and it was fixed 10 days ago. You should use the dev version (GMT 6.4) ---

Ah okay, thanks! I didn’t think to check pull requests!
