Resource-based cities: Spatial structure and evolutionary identification based on nighttime light images

open access: yesFrontiers in Earth Science, 2022
Dividing the development stage and grasping the best time to transition are significant for resource-based cities (RBCs). However, there is still a lack of research on how to judge the developmental stage of RBCs through objective indicators of urban ...

The spatial structure of networks [PDF]

open access: yes, 2004
We study networks that connect points in geographic space, such as transportation networks and the Internet. We find that there are strong signatures in these networks of topography and use patterns, giving the networks shapes that are quite distinct ...
