Abstract:

The convergence of Geographical Information Systems GIS and Statistical Dynamic Graphics has led to the development of a number of new concepts in spatial data analysis. This paper discusses how such ideas may be extended in the context of spatial modelling. The software environment we use - REGARD - incorporates the GIS ideas of point, line and region layers of data pertaining to an area under study. The spatial variation here is modelled by a variogram. The model may be used to generate new statistical views of the data, which may be regarded as diagnostics. Aspects of the model may be decomposed spatially in the linked-views environment. Many such aspects are naturally viewed as being defined point-wise. Aspects which refer to data pairwise can naturally be associated with line-objects. Many analyses are oriented to defining regions of anomalous behaviour. The paper will illustrate these intertwined ideas.
