How We Watch the City: Popularity and Online Maps
Microsoft Research
Danyel Fisher
ABSTRACT
One way of conceptualizing physical spaces is to look at
where people notice, remember, or note them. Computer-
assisted methods give us new tools based on implicit, rather
than explicit, data about how users have examined and
travelled online through cities. “Hotmap” is a tool that
visualizes how people have used maps.live.com, an
interactive mapping service, looking at what parts of the
maps they find most compelling.

Abstract:
This paper proposes a new spatial ordering index that that can be used to quantify the dependence of a given pattern of income segregation on the spatial arrangement of neighborhoods. Unlike other spatial measures of income segregation proposed in the literature, the spatial ordering index is less sensitive to the presence of outliers, satisfies the principle of transfers, and is flexible enough to quantify a variety of spatial patterns of segregation. The index can be interpreted in terms of the ratio of two covariances. Properties of the proposed measure are demonstrated using an example from the city of Baltimore, Maryland.

Exploring Changes in Income Clustering and Centralization during the 1990s

This article employs a new "spatial ordering index" to describe and explain changes in the degree of income clustering and centralization within U.S. metropolitan areas during the 1990s. The results suggest that while the spatial pattern of household income became more decentralized and less clustered during the 1990s, the patterns established as of 1990 were highly persistent over the decade. Factors associated with metropolitan area size and growth affected changes in both the degree of centralization and the degree of clustering. Although traditional determinants of suburbanization were associated with increases in income decentralization during the 1990s, densely developed cities with an increase in the percentage of white residents saw increases in income centralization during the decade. Furthermore, changes in the patterns observed were shaped by various policy influences, including the number of Low Income Housing Tax Credit units, urban containment policies, and the degree of local government fragmentation.
Key Words: economic segregation • spatial analysis • metropolitan governance • urban containment • growth management
