One of my friends and I used to always have this debate because of our different backgrounds. I got used to +Y being up because of doing physics for several years and seeing side-on diagrams that needed to account for gravity. My friend has a background in geology, so he's used to top-down surveying maps where +Z is up. It all depends on your perspective.
But my way is right. We need to have standards, people.
I'm like your friend, but my perspective is from the atmospheric sciences. The z-axis is anything vertical.
I wonder if all earth sciences are like this?
