Extending ArcObjects for Statistical Cancer Analysis
Track: Health and Human Services
Author(s): Harrison Brunton
The power of GIS does not lie in visualization alone. The ability to perform spatial and statistical analyses is a key aspect of cancer research. The U.S. National Cancer Institute's Long Island GIS (LI GIS) project developed four statistical extensions as part of a GIS that is available to investigators in studying breast cancer and the environment on Long Island: www.healthgis-li.com. These extensions are tools for Cluster Analysis and Empirical Bayes, a Disease Rate Calculator, and Areal Interpolator. Statisticians, epidemiologists, GIS analysts, and GIS programmers together developed the extensions.
This paper shows how ArcObjects and Visual Basic can be used to create extensions for statistical analysis of disease data. Topics include designing reusable modules and advantages of an object-based architecture.
Intricacies of migrating from Avenue to ArcObjects and converting from ArcObjects 8 to 9 are addressed.
