TL;DR: The state factor approach is used to highlight the role of important aspects of climate, substrate, organisms, relief, and time in differentiating urban from non-urban areas, and for determining heterogeneity within spatially extensive metropolitan areas.

TL;DR: In this article, the marginal values of different open space attributes were tested using a hedonic pricing model with residential sales data from central Maryland, and the identification problems that arise due to endogenous land use spillovers and unobserved spatial correlation were addressed using instrumental variables estimation with a randomly drawn subset of the data that omits nearest neighbors.

TL;DR: This article reviewed some of the advances that have been made by geographers and natural scientists in developing spatially disaggregate and explicit models of spatial land use change, focusing on their modeling of the economic process associated with land use changes.

TL;DR: Estimated fragmentation gradients that describe mean fragmentation as a function of distance from urban centers confirm the hypotheses that fragmentation rises and falls with distance and that the point of maximum fragmentation shifted outward over time.

TL;DR: In this article, a model of land use conversion that incorporates local spillover effects among spatially distributed agents is developed to test the hypothesis that fragmented patterns of development in rural-urban fringe areas could be due to negative externalities that create a'repelling' effect among residential land parcels.
