Conceptual overview of the Local Distance Network, a multi-route approach to deriving the Hubble constant in our universe. Included are a non-exhaustive collection of various methods for determining galactic distances and how these can connect the absolute scale established through geometric means to the Hubble constant H0. Background rectangles illustrate the positions of Rung 1, Rung 2 and Rung 3 in a traditional distance ladder from left to right. The graphic was developed within the framework of the IS
