Understated in the development both of scientific and critical approaches to the field of cartography has been the role of cartographic inference. Making inferences from maps is fundamental to the visual analytical tradition and the thinking/communication continuum. Reasoning is also fundamental to critical cartography and the development of critiques relies on inference based on “evidence” encoded or inscribed in a map or set of maps. The social construction of a map and the map’s use have a significant impact on the types of inferences that are made, but conclusions must be carefully scrutinized with respect to these inferences. This study examines the Piercean notions of abductive, deductive, and inductive inference and their application to cartographic inquiry from both scientific and critical perspectives. A study of John Snow’s famous map of a cholera outbreak in London shows the evolution of this map from an instrument of scientific inquiry to one of historical discourse. This historical discourse also shows the continuous unfolding of “Snow’s map” as a mapping practice. By understanding how logical inferences change over time as the context of a map within society changes, this study shows biases inherent within cartographic expression integral to both scientific and critical lines of inquiry.

Measuring differential access to facilities between population groups using spatial Lorenz curves and related indices / Gordon A. Cromley in Transactions in GIS, Vol 23 n° 6 (November 2019)

When population and facilities are not uniformly distributed across the landscape, inequities in accessibility may occur. Current research into GIS‐based accessibility measures has focused primarily on spatial inequities between different geographic locations but not directly on differences in accessibility between subgroups of the population. The research presented here develops a new method for measuring differential accessibility to facilities between various segments of the population. The method extends concepts and techniques in spatial point pattern analysis that account for the spatial structure of demand and its relationship to supply. In this approach, the traditional Lorenz curve and its associated indices, the Gini coefficient and the dissimilarity index, which are used to measure inequality, are recast in spatial terms for measuring differences in accessibility between population subgroups. An analysis of spatial accessibility to grocery stores in Akron, OH illustrates the value of the spatial Lorenz curve and its associated indices compared to other methods.
