SAS Global Forum 2011 Reporting and Information Visualization Paper 299-2011 Distance Mapping in Health and Health Care: SAS ® as a Tool for Health



Geomatics is the science concerned with using mathematical methods with spatial data to learn about the earth's surface. Health geomatics is used to improve the understanding of relationships between people, location, time, and health. Geomaticists assist in discovering and eliminating disease, aid in public health disease prevention and health promotion initiatives, and support healthcare service planning and delivery through defining spatial relationships. Distance mapping is one of many tools in the geomatics toolbox that furthers this understanding. SAS ® provides a comprehensive set of graphics tools and procedures as part of the SAS/GRAPH ® product that can be used for distance mapping, including the new GEOCODE procedure and the GEODIST function, available with SAS 9.2. This paper combines the graphics available in SAS/GRAPH with other available SAS tools to explore spatial relationships in the health care arena. Examples include maps, grid squares, area charts, and X-Y plots. The analytic graphics in this paper were developed with version 9.1.3 or 9.2 of SAS executing on a Windows XP platform. SAS 9.2 is required for the GEOCODE procedure. The graphics represented in this paper are not platformspecific and can be adapted by both beginning and advanced SAS users. BACKGROUND Health, disease, and health care differ from place to place and from time to time. While undertaking the analysis o
