22. The Data
• A single data repository: the Geodatabase
• Every geographic dataset,
business logic and behavior

23. The Map
• A set of geometric features that
represents a geographic reality.
• A ‘window’ for exploring the data.

24. The Model
• Analysis tools that creates new geographic information
from existing data.

25. In short, a GIS is…
An information system
(hardware, software, data)
which enables us to apply lots of
analysis models
to any geographical datasets
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.

34. Topology
• Branch of mathematics that studies geometry
from a qualitative perspective.
• Topology describes the geometric relationships
of a given space.
“ A topologist is someone
that can’t distinguish between a
cup of coffe and a doughnut
Data

35. Topology in our GIS
• Defines the way different point, line or polygon layers
relate each other geometrically.
Two contour lines can’t intersect
Two parcels can’t overlap
Buildings must be within parcels
Data

36. Behavior in our GIS
• Geometric features may have properties that represent
geographic objects.
Street network
(edges, junctions, turns, impedances)
Cadaster
(parcels, boundaries, nodes )

51. A GIS is…
An information system
(hardware, software, data)
that allows us to apply lots of
analysis models
to any set of geographic data
in order to generate derived information
that can be explored as a map.

52. Geographic Information Systems…
…help us understand reality…
…answer questions about our world…
…and support us during decission-making.

53. Where to begin
A piece of advice…

54. «The application of GIS is limited only
by the imagination of those who use it.»
