Varying spatial connectivity affects network size, with little effect on scaling (slope). Increasing the low luminance threshold reduces the size, number and connectivity of components, but does not change the slope of the rank-size distributions. For China, the lower threshold results in the interconnection of several large components to form a single very large component on the Changjiang delta and Yangtze River basin—thereby disrupting the scaling of the upper tail. A similar effect is seen in ranks 30 to 100 for the USA
