During the past year a complete digitized representation of pertinent spatial and aspatial data from the Upper Cape Study was entered into a Geographic Information System. The residential locations on all maps were digitized and a lengthy evaluation of the digitized data was performed to ensure that the representation was consistent with the paper maps and with the residential history database on file. In particular, investigators identified a number of inconsistencies that could have been introduced either in the process of digitizing, or in the original mapping. Comparing previously collected information to the digitized data, scientists identified which residences were missed in the digitization process. Inconsistencies within the digitized data were also identified, and all identifiable errors corrected. In parallel with the computerized mapping, new analytic techniques to analyze clustering in the digitized data have been developed. Lattice diagrams have been exploited to devise new strategies for exploratory data analysis and to obtain interesting theoretical results.
