Display of interactive artwork: pilot test of two different interfaces
The display of interactive artwork plays an increasingly important role in modern museums and galleries. However, the reaction of visitors has not been extensively tested to date. We present a pilot study that investigates ... -
Space, freedom, and law: maybe space is all that matters
The traditional causal, vectorial approach to formulation of physical law is contrasted to the analytic approach which is based on variational principles. Reviewing the work of Toffoli, these two “paradigms” are considered ... -
A preliminary investigation of the stability of Geographically-Weighted Regression
This paper describes preliminary work analysing the stability of parameter coefficient estimates for Geographically-Weighted Regression (GWR). Based on a large dataset (35721 points) various random samplings of this data ... -
Spatial variation in the association between neighbourhood deprivation and access to alcohol outlets
Background: People who live in poor areas suffer higher mortality than those living in wealthier areas. People who live in poor areas in New Zealand have better access to alcohol and this association appears to vary ... -
Development of an automated tracking system for analysis of human movement
To understand the mechanisms underlying a successful team, one must first understand the circumstances leading to successful performance outcomes (i.e., point/goal scoring events). However, tracking player performance in ... -
Two new tools for aggregation and geoprocessing of raw spatial data
The journey to successful data analysis is vulnerable to loss of accuracy at several key steps in its progression. Thus the ease of understanding the results and strength of insight into a work’s implications depends on ... -
Geographic information systems at AgResearch
AgResearch is New Zealand’s largest Crown Research Institute and undertakes research in the areas of pastoral agriculture and environment, applied biotechnologies, and food and textiles. While there is a great deal of scope ... -
Assessment of the performance of image fusion for the mapping of snow
The assessment of the performance of multi-resolution image fusion, or image sharpening methods, is difficult. In the context of binary classification of snow targets in mountainous terrain, fusion methods were applied to ... -
Spatial analysis of home range, core area and habitat selection of red deer (Cervus elaphus) on an extensively managed high-country station
The aim of this research was to determine the behavior and habitat selection of red deer (Cervus elaphus) hinds during the calving period, on an extensively managed rangeland in the high-country of New Zealand’s South ... -
The emergence and distribution of species in a gradient-based spatially-structured evolutionary algorithm
The ability to discover and maintain multiple solutions within a single run is a desirable property for evolutionary algorithms. Researchers have previously turned to many biologically-inspired methods for inspiration to ... -
The "Kawachi" algorithm: a single-parameter network constructor?
The last decade has seen resurgence of interest in the modelling of networked phenomena. In 1999, Albert and Barabási identified "scale-free" networks as being surprisingly widespread in phenomena as wide-ranging as the ... -
Does space always matter in the origin of biological species
For the last 40 years one of the most contentious issues in evolutionary biology has been determining the role that spatial separation of populations plays in the generation of new species. Most early formulations of this ... -
Point allocation inside polygons and GWR: an experimental analysis with survey data
The aim of this paper is to analyse different alternative implementations for a problem defined as "point allocation inside polygons" for Geographically Weighted Regression (GWR). The problem involves situations where the ... -
HD aerial video for coastal zone ecological mapping
The paper discusses a recent test of using High Definition (HD) video camera to obtain aerial mapping images for coastal zone study. Real-Time GPS was used to capture the ground control. It was revealed that the vibration ... -
Sea level change in New Zealand – spatial impacts from a surveyor’s perspective
The first comprehensive analysis of long-term sea level change in New Zealand was completed in 1990. That analysis revealed an average rise in sea levels around the New Zealand coastline of 1.7 mm/yr since 1900. A more ... -
The effect of spatial population structure on levels of genetic variation
A vast amount of genetic variation is a striking hallmark of natural populations, and is vital to the adaptation and long-term survival of a species. Just why this variation is there, however, is unclear: the two most ... -
The ARGOS project and the role of GIS
The paper introduces ARGOS, the Agriculture Research Group on Sustainability and discusses the potential role GIS can play within. The ARGOS programme examines the environmental, economic and social sustainability of ... -
Some approaches to the analysis of replicated bivariate spatial point patterns: Drosophila retina
With advances in technology and microscopy, many biologists are finding that their data take the form of replicated spatial point patterns. These are patterns in which the locations of points are the main interest. ... -
Beginning research on the quantification of spatial order
This research was conceived to contribute to the theoretical foundations of a general view of the dynamics of the world based on a concept of spatial order, defined and quantified in terms of differences or gradients. The ... -
Revealing the local geospatial knowledge base of oyster fishing at Bluff, New Zealand
This presentation discusses and demonstrates ways in which modern technology, specifically Web-based GIS (augmented by low-tech data gathering strategies), and a web page based on local meetings of fishermen and other ...
