(Conference or Workshop Item (Oral presentation), 15th Annual Colloquium of the Spatial Information Research Centre (SIRC 2003: Land, Place and Space), 2003)This talk will address the problem of determining the semi-rigid motion of an ice floe from a series of grayscale images of the floe. The analysis will start with the global properties of the images. The next step is to ... -
(Conference or Workshop Item (Oral presentation), 18th Annual Colloquium of the Spatial Information Research Centre (SIRC 2006: Interactions and Spatial Processes), 2006)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 New ... -
(Conference or Workshop Item (Oral presentation), 15th Annual Colloquium of the Spatial Information Research Centre (SIRC 2003: Land, Place and Space), 2003)Modelling the relationship between the genetic distribution of a biological system on a landscape, and the diversity of this system, are fundamental concepts that can be studied using simulation models. This work examines ... -
(Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)We have used the DNA sequences of Pacific topshells, belonging to the genera Diloma, Melagraphia and Austrocochlea, to ascertain how this group became established over a large area of the Pacific. Phylogenetic analyses of ... -
(Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)We present a new method for calculating the transformation parameters for a rigid body undergoing planar motion parallel to the image plane. The method utilises splines to represent the outline of the rigid shape rather ... -
(Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)The conservation status of New Zealand's indigenous grasslands has been assessed, as of September 2002, against an 1840 baseline, i.e., immediately before European settlement when New Zealand grasslands were essentially ... -
(Conference or Workshop Item (Oral presentation), 17th Annual Colloquium of the Spatial Information Research Centre (SIRC 2005: A Spatio-temporal Workshop), 2005)Reintroduction of threatened species to predator-free offshore islands has long been advocated in New Zealand as a prime management tool for conservation. They also provide a good experimental framework to investigate ... -
(Conference or Workshop Item (Oral presentation), 18th Annual Colloquium of the Spatial Information Research Centre (SIRC 2006: Interactions and Spatial Processes), 2006)A Dynamic map is implemented and tested using a cartogram algorithm to distort space to enlarge any areas of user interest. The map organises space into a hierarchy of shapes, island at the country level, provinces at the ... -
(Conference or Workshop Item (Oral presentation), 19th Annual Colloquium of the Spatial Information Research Centre (SIRC 2007: Does Space Matter?), 2007)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 ... -
(Conference or Workshop Item (Oral presentation), 15th Annual Colloquium of the Spatial Information Research Centre (SIRC 2003: Land, Place and Space), 2003)Measurements of vegetation structure (the three dimensional placement of the vegetation biomass) and structural diversity (the number of vegetation layers present and the abundance of vegetation within them) are required ... -
(Conference or Workshop Item (Oral presentation), 19th Annual Colloquium of the Spatial Information Research Centre (SIRC 2007: Does Space Matter?), 2007)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 ... -
(Conference or Workshop Item (Oral presentation), 19th Annual Colloquium of the Spatial Information Research Centre (SIRC 2007: Does Space Matter?), 2007)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 ... -
(Conference or Workshop Item (Oral presentation), 15th Annual Colloquium of the Spatial Information Research Centre (SIRC 2003: Land, Place and Space), 2003)I describe a model for the evolutionary consequences of plasticity in an environmentally heterogeneous metapopulation in which specialists for each of two alternative environments and one plastic type are initially present. ... -
(Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)Agricultural expansion is a major threat to the indigenous biodiversity of New Zealand’s tussock grasslands. Options for integrating biodiversity conservation with agricultural management is a topic that requires further ... -
(Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)Glacier fluctuations have been recognized as one of the clearest signals of climate variability and change. A change in climate characteristics directly alters the glacier mass balance. The End-Of-Summer-Snowlines (EOSS) ... -
(Conference or Workshop Item (Oral presentation), 19th Annual Colloquium of the Spatial Information Research Centre (SIRC 2007: Does Space Matter?), 2007)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 ... -
(Conference or Workshop Item (Oral presentation), 17th Annual Colloquium of the Spatial Information Research Centre (SIRC 2005: A Spatio-temporal Workshop), 2005)The leading cause of mortality in 15-24 year-olds in New Zealand is injury, accounting for three quarters of deaths. Road traffic crashes account for over half of all injury deaths and a third of hospitalisations, and ... -
(Conference or Workshop Item (Oral presentation), 16th Annual Colloquium of the Spatial Information Research Centre (SIRC 2004: A Spatio-temporal Workshop), 2004)At the Wangaloa Coal Mine, South-East Otago, ArcGIS is being used to manage, integrate, analyse and visualise the diverse range of datasets being generated from an interdisciplinary research team. GIS will assist with ... -
(Conference or Workshop Item (Oral presentation), 15th Annual Colloquium of the Spatial Information Research Centre (SIRC 2003: Land, Place and Space), 2003)Less than 5% of the land on New Zealand’s coastal plains is still in predominantly indigenous habitats, falling to less than 2% across much of the Southland and Manawatu coastal plains. The protection, conservation, and ... -
(Conference or Workshop Item (Oral presentation), 17th Annual Colloquium of the Spatial Information Research Centre (SIRC 2005: A Spatio-temporal Workshop), 2005)Hector’s dolphins are an endemic species found along coasts in both the North and South Islands in New Zealand. They are primarily observed along the coast within 5 nautical miles (nm) of the shore. Surveys conducted during ...
