Hi,
I have a 0.1ºx0.1º point dataset that represents global ocean bathymetry in meters. I need to make a map of angles each point make to mean sea level (horizontal). I was looking at the slope/gradient function, but that requires x, y and depth in the same unit and in my dataset, x, y is in decimal degrees that if converted to meters will change along changing latitude. So is there any way I can perform this correctly?
The final product that I want would be similar to the what this picture shows in polygon format, where major break in gradient will be a polygon.
Thanking you in advance.
