Maps are everywhere—on the Internet, in our car, and even on our mobile phone. Moreover, maps of the twenty-first century are not just paper diagrams folded like an accordion. Maps today are colorful, searchable, interactive, and shared. This transformation of the static map into dynamic and interactive multimedia reflects the integration of technological innovation and vast amounts of geographic data. The key technology behind this integration, and subsequently the maps of the twenty-first century, is geographic information systems or GIS.

3. WHAT IS GIS?
A Geographic Information System designed to
capture, store, manipulate, analyze, manage and
present all types of spatial or geographical data.

6. Father of GIS
The first known use of
the term “Geographic
Information System" was
by Roger Tomlinson in
the year 1968 in his paper
"A Geographic
Information System for
Regional Planning".
ROGER TOMLINSON (1933-2014)

13. Information is Organized into layers

14. By combining layers and using operators and
displays, GIS enables us to work with these
layers to explore questions and find answers.

15. APPLICATION OF GIS

16. CRIME MAPPING
Every crime problem is
related to some location,
whether it’s an address,
street, ZIP Code, or
district. GIS can help you
leverage the locational
aspect of your data to
analyze, understand, and
build solutions to the
problems you face.

17. With the help of GIS we can understand the
risks, develop proactive adaptation
strategies, and increase society’s long-term
resilience to climate change through policy
modification.

18. EMERGENCY MANAGEMENT
GIS can help you with all phases of
emergency management, from developing
mitigation plans to managing limited
resources in the midst of chaos and
prioritizing recovery efforts once the dust
settles.

19. HELPING ENGINEERS
GIS technology provides a
central location to conduct
spatial analysis, overlay data,
and integrate other solutions
and systems. Built on a
database rather than
individual project files, GIS
enables engineers to easily
manage, reuse, share, and
analyze data, saving time and
resources.
