Short summary
How good are measurements of shapes in the landscape? This is not well constrained. We suggest that "synthetic tests" using constructed digital landscapes called synthetic DEMs are a powerful and necessary tool to establish the reliability of these data (e.g. mapped sizes). Thus, the tests have a key, complementary role in determining if conceptual and physics-driven models of processes can be reconciled with morphological observations of reality. A typology of synthetic DEMs is proposed.
