  author={Colin Robertson and Trisalyn A. Nelson and Barry Boots and Michael A. Wulder},
  journal={Journal of Geographical Systems},
Research questions regarding temporal change in spatial patterns are increasingly common in geographical analysis. In this research, we explore and extend an approach to the spatial–temporal analysis of polygons that are spatially distinct and experience discrete changes though time. We present five new movement events for describing spatial processes: displacement, convergence, divergence, fragmentation and concentration. Spatial–temporal measures of events for size and direction are presented… 

stampr: Spatial-Temporal Analysis of Moving Polygons in R

Methods described in this paper include deriving change events based on spatial relationships, plotting change events, summarizing measures of distance and direction of movement, characterizing changes in polygon shape changes, and characterizing sequences of polygons over time using graphs.

Quantitative versus Qualitative Geospatial Data in Spatial Modelling and Decision Making

In general, geospatial data can be divided into two formats, raster and vector formats. A raster consists of a matrix of cells where each cell contains a value representing quantitative information,

Trends in Spatial Statistics

With many leading spatial analysts nearing retirement, reflection on the discipline becomes beneficial. To capture some of their collective perspective, fifty-eight researchers were surveyed on key

Research in the spatial sciences: how are Canadian geographers contributing?

Geographic data collection, manipulation, analysis and visualization options have experienced substantial improvements during the past several decades, largely spurred by advancements in computing



Area-based tests for association between spatial patterns

Abstract. Edge effects pervade natural systems, and the processes that determine spatial heterogeneity (e.g. physical, geochemical, biological, ecological factors) occur on diverse spatial scales.

Exploratory Method for Analyzing Changes in Polygon Distributions

An exploratory method for analyzing changes in polygon distributions is developed and applied to the analysis of changes in market areas of a convenience-store chain in Tokyo, Japan, revealing the spatial structure ofChanges in a global scale.

It's About Time: A Conceptual Framework for the Representation of Temporal Dynamics in Geographic Information Systems

Abstract The study of spatiotemporal dynamics is certainly not new, nor is it unique to the field of geography. Nevertheless, addressing complex human and environmental issues such as global warming

Representation and Spatial Analysis in Geographic Information Systems

Abstract A common—perhaps modal—representation of geography in spatial analysis and geographic information systems is native (unexamined) objects interacting based on simple distance and connectivity

A computational approach for the analysis of changes in polygon distributions

A computational procedure for deducing a set of events from polygon distributions of two times is proposed and is applied to the analysis of the spatial competition between the major and small chains of convenience stores in Tokyo, Japan.

Exact Computational Methods for Calculating Distances Between Objects in a Cartographic Database

Most existing spatial analytic techniques use a simplified, point-based representation of spatial objects. This facilitates tractability of the standard computational procedures for many spatial

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.

Point-Set Topological Spatial Relations

Practical needs in the realm of Geographic Information Systems (GISs) have driven the efforts to investigate formal and sound methods to describe spatial relations. After an introduction of the basic

A Mark 1 Geographical Analysis Machine for the automated analysis of point data sets

A GAM offers an imaginative new approach to the analysis of point pattern data based on a fully automated process whereby a point data set is explored for evidence of pattern without being unduly affected by predefined areal units or data error.
