5. Components of GIS

6. GIS Tools for Social Impact
• the social consequences of GIS technologies go far beyond problem-
solving to actually influencing the goals.

7. GIS and Public Health?
LONDON (1831-1854)
• Cholera is an intestinal disease than
can cause death within hours after
the first symptoms of vomiting or
diarrhea
• 1831- The first cases of cholera in
England were reported in England
• 1831-1854 (24 YEARS)- THOUSANDS

10. In spite of the late
numerous deaths,
we have all the
materials for a fresh
epidemic
If I can establish
the location of
incidences…..
We can STOP
the spread.!!!

16. • GIS support public health in different ways:-
– GIS displays (Visualization)- help inform proper
understanding and drive better decisions
– identify and develop solutions to address those
shortcomings
– integrate disparate data from a wide variety of
sources
GIS and Public Health?

17. CONCLUSION
• Public health efforts have been based on analysis
and use of spatial data for many years
• Today’s health decision making depend on
modern GIS and other computer mapping
applications
• GIS as a tool for Spatial Decision Support systems
offers improved Geographic Data collection,
Analysis, Visualization techniques
– leading to faster, better, and more robust
understanding and decision-making capabilities in the
public health arena

numerous deaths,
we have all the
materials for a fresh
epidemic
Hmnnnm!…with
GIS….. WE CAN
STOP many
other
epidemic!!!
