In our introductory column in November, I spoke of profiling right-minded environmental health projects that address the numerous challenges agencies face today. I know that citizens want more information about the health of their communities. They expect answers (and not just data, but conclusions) faster than ever before. GIS stands out as a tool health agencies must utilize to meet this pressing need. The best application of GIS technology can bring about far-reaching insight and manifest inferences about the relationship between our environment and our health never before imagined.
