Introduction
GeoBUGS is an add-on module to WinBUGS which provides an interface for:
*
producing maps of the output from disease mapping and other spatial models
*
creating and manipulating adjacency matrices that are required as input for the
spatial models available in OpenBUGS for carrying out spatial smoothing.
GeoBUGS contains map files for
* Districts in Scotland (called
Scotland
)
* Wards in a London Health Authority (called
London_HA

A list of the area IDs for each map and the order in which the areas are stored in the map file can be obtained using the
export Splus command.
GeoBUGS also has facilities for importing user-defined maps reading polygon formats from
Splus,
ArcInfo and
Epimap, plus a link to a program written by Yue Cui for importing
ArcView shape files.
