Mapping with GIS

Why use maps to communicate a message?

 Maps are a compact and elegant method of communicating information. With a well-designed map, a reader should be able to quickly interpret the displayed information without assistance. Today, the most efficient and effective method of producing maps that communicate a message is with a computer-based Geographic Information System (GIS).

Maps and MEDRIX

MEDRIX staff teaches health care professionals how to use GIS maps to display health care data. The latest classes were taught in Vietnam in March 2016 by Robert Catherman. The medical doctors in this class were quick to learn GIS skills and eager to use GIS technology to display results of their research and projects. gis class


Free GIS software and training curriculum

Because licenses for use of GIS software can be quite expensive, MEDRIX uses free open source GIS software in our classes. In addition, MEDRIX-developed curriculum is also open source and downloadable here. This curriculum teaches the GIS workflow beginning with how to download GIS software and maps and concluding with producing the finished map for printing or inserting in PowerPoint presentations. The curriculum is useful for teaching in the classroom setting or for self-study use by individuals to learn the basics of GIS.

Good reading recommendation

The fascinating history of the beginning of the use of GIS in health care is told in the New York Time’s best seller book “The Ghost Map” by Steven Johnson, 2006. The story revolves around the cholera epidemic of 1854 in London and how Dr John Snow used a map to change the world’s understanding of how cholera was spread.
