TL;DR: A method is proposed which delineates the service area of providers delivering social services and produces a probability metric that maps the equity of the program of services for each household and proposes an adjustment process, an allocation, to level access to services.
Abstract: Although social programs intend to provide equal access for all, in the final evaluation, fairness of the distribution of services is usually dictated by location. Measuring and predicting access to social services can help these programs adjust and better accommodate under-served regions. A method is proposed which delineates the service area of providers delivering social services and produces a probability metric that maps the equity of the program of services for each household. We begin with a computationally trivial method for delineating service areas, map the probability of households being served, and propose an adjustment process, an allocation, to level access to services. We argue such methods can serve to better locate service providers and insure equity when implementing social programs.

TL;DR: This research develops a desktop tool by calling the Google Maps Application Programming Interface (API) to tap into the dynamically updated transportation network data and the routing rules maintained by Google and obtain a reliable estimate of O–D travel time matrix.
Abstract: Many spatial analysis tasks call for the use of travel time between multiple origins and destinations, that is, O–D travel time matrix. Commercial geographical information systems (GIS) software re...

TL;DR: This article further elaborates on the nature of the UGCoP and explores how recent advances in geographical information system (GIS) and geospatial technologies can help address the problem.
Abstract: The uncertain geographic context problem (UGCoP), first articulated by Kwan (2012; The uncertain geographic context problem. Annals of the Association of American Geographers, 102 (5), 958–968), refers to the problem that findings about the effects of area-based contextual variables on individual behaviors or outcomes may be affected by how contextual units (e.g., neighborhoods) are geographically delineated and the extent to which these areal units deviate from the true geographic context. It is a significant methodological problem because it means that analytical results can differ for different delineations of contextual units even if everything else is the same. Drawing upon Kwan (2012) and recent social science studies (especially environmental health and neighborhood effects research), this article further elaborates on the nature of the UGCoP and explores how recent advances in geographical information system (GIS) and geospatial technologies can help address the problem. It discusses possible mean...

TL;DR: A personal view on some emerging research directions at the interface of social science and spatial analysis is presented, with particular emphasis on methodological challenges presented by developments in social science theory, demands for data manipulation, and the need for education and dissemination.

TL;DR: The need for a typology of map mashups is suggested while arguing that such a typologies is premature and the need for standards and formats is discussed, moving on to questions of security, privacy and confidentiality.
Abstract: Mashups, composed of mixing different types of software and data, first appeared in 2004 and ‘map mashups’ quickly became the most popular forms of this software blending. This heralded a new kind of geography called ‘Neogeography’ in which non-expert users were able to exploit the power of maps without requiring the expertise traditionally associated, in the geographic world, with cartography and geographic information science, and, in computer science, with data structures and graphics programming. First we suggest the need for a typology of map mashups while arguing that such a typology is premature. We then discuss the need for standards and formats, moving on to questions of security, privacy and confidentiality. We follow this by introducing the key issues of creating spatial data for mashups through crowd-sourcing. To ground this presentation in applications, we explore some classic exemplars from our own and related work with map mashups and portals such as MapTube (http://www.maptube.org/). We th...
