The document provides an introduction to geographic information systems (GIS) including: - A definition of GIS as an integrated system that combines geographic and tabular data using software for analysis and presentation of that analysis in map form. - A brief history of early GIS maps including John Snow's 1855 cholera map, one of the first epidemiological maps. - An overview of current applications of GIS including 3D modeling, web-based GIS, and a wide range of uses in fields such as urban planning, environmental science, business, health care, and more. - A quote from GIS pioneer Jack Dangermond that the applications of GIS are limited only by users' imaginations

3. What is GIS?
Almost everything that happens, happens somewhere
Knowing where something happens can be critically important
An ensemble of geographic and tabular data, using software that allows analysis and
presentation of such analysis in map incorporates databases and spreadsheets with spatial
information in one integrated system

4. GIS allows us to view, understand, question,
interpret, and visualize data in many ways
that reveal relationships, patterns, and
trends in the form of maps, globes, reports,
and charts
A GIS helps you answer questions and solve
problems by looking at the data in a way that
is quickly understood and easily shared
GIS is about data visualization
GIS is about telling a story

5. Historical GIS Maps

6. Snow’s Cholera Map (1855) - The first epidemiological map illustrates cholera cases in
relation to water pumps

7. GIS Today

11. 3D GIS

Planning 3D urban

12. Web GIS
Web maps are online maps
that provide a way to work
and interact with geographic
content organized as layers

18. GIS Applications
In addition to fun and daily usages, GIS is a
very powerful professional skills
Nowadays, it is very difficult to find
something that don’t need GIS
It has been widely used in management,
industry, and research (social and nature)
The application of GIS is limited only by the
imagination of those who use it
