Conceptual overview of the Local Distance Network, a many routes approach. Different methods for distance determination may connect the absolute scale determined by geometric means to H0. Background rectangles indicate from left to right where Rung 1, Rung 2, and Rung 3 of a traditional distance ladder would fall. Graphic by Fabio Crameri, ISSI, based on original from Casertano et al. (2025). Figure available from https://s-ink.org/local-distance-network
