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. A nonexhaustive list of baseline linkages discussed in the literature or the paper is labeled on the right. Links to geometric distances provided by masers, DEB, and parallaxes are indicated as available in our analysis. Background rectangles in orange, light blue, and gray indicate where Rung 1, Rung 2, and Rung 3 of a traditional distance ladder would fall. Unlabeled tick marks represent groups (Fornax & Virgo for the TRGB to SBF, Coma for FP). Example references: Riess et al. (2022b, SH0ES), Freedman et al. (2025, CCHP), Anand et al. (2021, EDD), Anand et al. (2024b, Pop-II), Pesce et al. (2020a, MCP), de Jaeger et al. (2022, Pop-I), Kourkchi et al. (2020, CF4), Said et al. (2025, DESI), Vogl et al. (2025, adh0cc). Appendix C.1 replicates a subset of these routes.
