ABSTRACT
Use
of GIS in public health is currently limited to tracking immunizations,
disease surveillance, and establishing new service areas. The potential
of GIS to improve planning, implementation and monitoring of programs
and to inform policymaking processes for universal access to healthcare
is grossly underutilized. Major reasons for restricted use are paid
access to GIS software and difficult interpretation for non-GIS
professionals. WebGIS technologies present an opportunity for non-GIS
public health professionals to present complex data and findings in
simpler manner. Conventional GIS methods and Geovisualization are
compared and contrasted in this paper using data from the MATIND project
in the Gujarat state of India. In-depth literature review on GIS
techniques used in health implementation research was conducted. In this
paper, MATIND data have been used for comparing conventional GIS
methods with a newer web based GIS tool-Geovisualization. GIS software
is more useful for analytical purposes; whereas web based
geovisualization techniques are much better for visualization and easy
interpretation of results by non GIS public health researchers. As the
images are easy to interpret, interactive/dynamic and not much technical
expertise is required to perform basic analysis, the tool is useful for
policy makers and planners. Geovisualization provides a user-friendly
tool for presenting large scale community based survey data. Increased
use of this tool will help to present implementation research in a
creative way to the program planners and policy makers. For program
managers, it is a useful tool to monitor implementation and impact of a
program to improve health of population.
