A brief review of distance measurement methods for some astronomical sources is presented. Galactic plasma density distribution as related to the distribution of radio pulsars is discussed and a method for constructing relations between dispersion measure and distance for Galactic radio pulsars in small solid angle intervals is described. Dispersion measure - distance relations for radio pulsars based on this approach in the Galactic longitude and latitude intervals of Δl=0°±2° and Δb = 0°± 2° are displayed and comparisons are made with the predictions of the two commonly used models
