At the edges of the 6 gnomonic projection sections that make up a cube-inflated-to-a-sphere, when the altimetry data is being interpolated due to data resolution limits, there are graphical artifacts that appear.
- Odd shadowing patterns that originate from misplaced triangles on the seam
- Incorrect bicubic-interpolated slope for continuous slope-match interpolation, resulting in a visual trench or cliff
On a few bodies, there are instead large artifacts (or real geological structures) in the existing dataset that can cause similar symptoms. This is the case on Phobos.
