Ordinary kriging, a spatial interpolation technique, is commonly used in social sciences to estimate neighborhood attributes such as physical disorder. Universal kriging, developed and used in physical sciences, extends ordinary kriging by supplementing the spatial model with additional covariates. We measured physical disorder on 1,826 sampled block faces across four U.S. cities (New York, Philadelphia, Detroit, and San Jose) using Google Street View imagery. We then compared leave-one-out cross-validation accuracy between universal and ordinary kriging and used random subsamples of our observed data to explore whether universal kriging could provide equal measurement accuracy with less spatially dense samples. Universal kriging did not always improve accuracy. However, a measure of housing vacancy did improve estimation accuracy in Philadelphia and Detroit (7.9 percent and 6.8 percent lower root mean square error, respectively) and allowed for equivalent estimation accuracy with half the sampled points in Philadelphia. Universal kriging may improve neighborhood measurement.
In this article I explore how an integrated approach to the anthropological study of urban space would work ethnographically. I discuss four areas of spatial/cultural analysis—historical emergence, sociopolitical and economic structuring, patterns of social use, and experiential meanings—as a means of working out of the methodological implications of broader social construction theoretical perspectives. Two plazas in San Jose, Costa Rica, furnish ethnographic illustrations of the social mediating processes of spatial practices, symbolic meaning, and social control that provide insight into the conflicts that arise as different groups and sociopolitical forces struggle to claim and define these culturally significant public spaces.
