A GIS integrates hardware, software and data
to capture, manage, analyze and visualize
any kind of information with a geographic component.

You do not really understand something unless you can explain it to your grandmother.
Albert Einstein
Theoretical Physicist, unfortunately not related to GIS

Three perspectives
Map
Data
Models
-
The Data
A single data repository: the Geodatabase Every geographic dataset,
business logic and behavior
-
The Map
A set of geometric features that represents a geographic reality.
A window for exploring the data.
-
The Model
Analysis tools that creates new geographic information from existing data.
-
In short, a GIS is
An information system (hardware, software, data)
to any geographical datasets
which enables us to apply lots of analysis models
for generating derived information
that can be visualized as maps.
A Geographic Information System helps us understand our world,
answer questions about our environment and support us during decision-making.

Topologic integration
Data
-
Branch of mathematics that studies geometry from a qualitative perspective.
Topology describes the geometric relationships of a given space.
Topology
A topologist is someone that cant distinguish between a
cup of coffe and a doughnut
Data
-
Topology in our GIS
Defines the way different point, line or polygon layers relate each other geometrically.
Two parcels cant overlap
Two contour lines cant intersect
Buildings must be within parcels
Data
-
Behavior in our GIS
Geometric features may have properties that represent geographic objects.
Cadaster (parcels, boundaries, nodes )
Street network (edges, junctions, turns, impedances)

-
Geographic Information Systems
help us understand reality
answer questions about our world
and support us during decission-making.
-
A piece of advice
Where to begin
-
The application of GIS is limited only by the imagination of those who use it.
