The data for use in all of the Module 3 GIS and Spatial Analysis exercises are now available for download from:

These data are also on the "S" drive for access when on campus.
I'll be adding further information and discussion as the module progresses, you might also care to look back at blog posts tagged GIS and Spatial Analysis (DL) where you'll find information passed onto the Year 2 DL students who have already completed this module.
