Hagerstrand's time geography is a powerful conceptual framework for understanding constraints on human activity participation in space and time. However, rigorous, analytical definitions of basic time geography entities and relationships do not exist. This limits abilities to make statements about error and uncertainty in time geographic measurement and analysis. It also compromises comparison among different time geographic analyses and the development of standard time geographic computational… 

Time Geography and Space–Time Prism

Time geography is a constraints-oriented approach to understanding human activities in space and time that recognizes individual histories and the importance of geographic context.

A Field-Based Theory for Time Geography

Classic time geography is powerful but rigid, admitting only uniform travel velocities. Computational time geographic methods that resolve the uniform velocity assumption through transportation

Time geographic fields : A continuous velocity theory for time geography

1. Overview Time geography is powerful but until recently has only been a conceptual framework. Over the past decade or so, researchers have improved the rigor of time geography through

A spatial data model for urban spatial–temporal accessibility analysis

A velocity model is developed for a traffic network and walking surface-constrained travel environment through the divide-and-conquer principle and is demonstrated the usefulness of the model for studying the space–time accessibility of a moving object over a study area with varying spatial structures.

Incorporating Uncertainty into Time-geographic Density Estimates

This research develops an approach for explicitly incorporating GPS error into timegeographic density estimates, and quantified the magnitude of positional error for GPS waterfowl-tracking devices under five different land cover types.

The elements of probabilistic time geography

This paper starts with the standard assumption of time geography (no further knowledge), and develops the appropriate probability distribution by three equivalent approaches.

Beyond the Boundary: New Insights from Inside the Space-Time Prism

This chapter provides some novel insights into the internal structure of the prism, which can improve not only the theoretical understanding of the space-time prism but also practical applications.

Toward a kinetic-based probabilistic time geography

The goal of this paper is to synchronize two new ideas, probabilistic time geography and kinetic-based time geography, to develop a more realistic set of movement constraints that consider movement probabilities related to object kinetics.



Conceptualizing and Measuring Accessibility within Physical and Virtual Spaces

The study of accessibility in geography and related disciplines has a distinguished history dating back to Ravenstein’s work over a century ago. In the late 1940s to the 1960s, scholars such as Zipf,

Representations of Space and Time

It is a major premise of Peuquet's book that computer-based, spatial-temporal representations should be informed by human cognition, and her book divides her book into two (unequal) parts, possibly reflecting her belief that the balance in H-C interaction should be reversed.

Measuring Space‐Time Accessibility Benefits within Transportation Networks: Basic Theory and Computational Procedures

Space-time accessibility and benefit measures that are consistent with the rigorous Weibull axiomatic framework for accessibility measures are derived that reflect the locations, distances and travel velocities allowed by an urban transportation network.

Time in geographic information systems

A conceptual model of geographic change that treats only changed data over time, then extends the conceptual model to common geographic data types, and introduces a taxonomy of multidimensional access methods for solving the problem of responding to ad hoc queries to a spatiotemporal database.

In this paper, the derivation and manipulation of space-time prism concepts within a geographical information system (GIS) are discussed and a generic GIS based procedure is presented.

Minimum-cost distances in spatial analysis

An axiomatic approach to distance is developed which focuses on thosebehavioral concepts of distance related to movement in space which extend the classical notions of paths, path lengths, and shortestpaths in metric spaces.

Human Extensibility and Individual Hybrid-accessibility in Space-time: A Multi-scale Representation Using GIS

A focus on the individual enabled by GIS methods also reveals the spatial-temporal complexity in individual activity patterns and accessibility through 3D visualization or computational procedures.

Representation and Manipulation of Moving Points: An Extended Data Model for Location Estimation

A classification for spatio-temporal systems based on the properties of the represented objects is introduced, and it is claimed that features of some complex objects can be derived from those of simpler ones, suggesting an evolutionary approach.
