• Generic vector-agents 

    Hammam, Yasser; Moore, Antoni; Whigham, Peter A; Freeman, Claire
    The work reported here has been motivated by the need for a generic spatial model to overcome the limitations of Cellular Automata (CA) regarding the rigid square-cell structure and limited neighbourhood configurations. A ...
  • Irregular vector-agent based simulation for land-use modelling 

    Hammam, Yasser; Moore, Antoni; Whigham, Peter A; Freeman, Claire
    Urban structures exhibit complex patterns made of heterogeneous and irregular objects. Few works in the computational urban modelling literature have considered and examined the real geometric boundary of the city’s objects. ...
  • Nitrogen species distribution in the Taieri Plain aquifer, New Zealand 

    Kensington, Christopher; Richards, Katrina; Murray, Dave; Peake, Barrie
    Nitrogen contamination of drinking water has been linked to health risks including ‘blue baby syndrome’. In New Zealand, up to 51% of people use at least some groundwater for drinking, and there is growing concern that the ...
  • The storage and reconstruction of polygon boundaries using circles 

    Moore, Antoni; Mason, Chris; Whigham, Peter A; Thompson-Fawcett, Michelle
    This paper investigates the accuracy of using circles to store polygon boundaries. Can a series of xy points be accurately replaced by a smaller array of variably-sized circles used in a non space filling sense to approximate ...
  • Towards topoclimate maps of frost and frost risk for Southland, New Zealand 

    Richards, Katrina; Baumgarten, Mandy
    The spatial distribution of radiation frosts is closely associated with topographic patterns, and this link makes frost an obvious candidate for topoclimate mapping. There are several potential approaches involving field ...
  • A vector-agent paradigm for dynamic urban modelling 

    Hammam, Yasser; Moore, Antoni; Whigham, Peter A; Freeman, Claire
    In the past, researchers and model developers were restricted by their theoretical knowledge about the city and how it might be simulated as well as constrained by technological limitations. Nevertheless, the simulation ...
