Summary

Captures the Complexity of GIS for the Non-Specialist in a Ready-To-Implement WayUse of GIS applications in the medical community is not a new concept by any means. But, the ability to apply GIS technology on a wide scale is often hampered by the sophistication and complexity of the methodology and the limited access to affordable software. Spatial Epidemiological Approaches in Disease Mapping and Analysis illustrates the utilities of freeware using real-world data and leads users down the logical decision-making path toward developing spatial-statistical relationships.Wide-Ranging Overview of GIS Applications to Contemporary Health ProblemsThis internationally reputable guide brings instructional clarity to its treatment of spatial-statistical techniques, subjecting epidemiological data to statistical rigor and advanced methodological testing. With the help of a vivid color insert, this book illustrates the applications of GIS inexamining non-contagious (asthma and dengue) and contagious (SARS) diseases, making it applicable to any public health condition on any scale.  This landmark work follows a truly interdisciplinary model, capturing the complexity of GIS for the non-specialist in a ready-to-implement way and spotlighting the global challenge of analyzing public health concerns in a geographical context.
