What cell sizes are used to represent the shaded relief?

Shaded relief layers based on GTOPO30 are represented in 30, 60, and 120 arc-second cells. The approximate equivalent metric values are 1, 2, and 4 kilometers. Shaded relief layers from the 3DEP data in The National Map are derived from input data that are represented in 1/3, 1, 4, 8, and 16 arc-second cells. The approximate equivalents in meters are 10, 30, 120, 240, and 480.
