GEOGRAPHY

, GEOGRAPHIC INFORMATION SYSTEMS [GIS]
GIS → computerized system consisting of or hardware, software, data, people &
methods designed to read, manage, manipulate, analyse, model & display spatial
geographic data  complex planning & solve management problems

• Geography: Study of the Real World. Physical and cultural world with its spacing
patterns of people, the environment and their interaction with each other.
• Information: Set of processes that use raw data to compile information that can
be used in decision-making processes
• Systems: group of bound objects and activities that act on each other



NOTES: 5 COMPONENTS:

, 7 ELEMENTS:

1. Sun = source of electromagnetic energy
2. Solar energy = waves > travel through atmosphere [satellites = energy (radio waves)]
3. Energy = Earth's surface > wavebands & interaction with surface [absorbed, radiated,
reflected back]
4. Remote sensors = energy detected in different wavebands &right-isolate information
5. Energy information = electronic signals → ground station (converting information >
maps > satellite imagery)
6. People → satellite imagery = information about Earth
7. Maps / models = develop new knowledge about area / help solve environmental
problems

DATA must first be spatially referenced in a coordinate system = georeference(GeoRef
in short)

SPATIAL & SPECTRAL RESOLUTION

ELECTROMAGNETIC ENERGY SATELLITES & SENSORS
[SPECTRAL RESOLUTION] [SPATIAL RESOLUTION]
→ wavelengths = bands → each = sensors > detect information
→ detect sensors on satellites = energy beyond [describes quantity/size of image elements in
visible spectrum PIXELS]
→ ability of the sensor to detect information
across multiple spectrum bands of the
electromagnetic spectrum




High Resolution Med. Resolution Low Resolution




4 TYPES OF DATA

Spatial features = point, line or area characteristics [ geographic data = shape and the
absolute and relative position of all geographic features displayed]

Non-spatial data ( attribute data ) = information describing the spatial characteristics
of the spatial features or objects

, RASTER, VECTOR AND REAL WORLD DATA


Vector data = shows geographic
features in the form of basic geometric
objects such as points, lines, and polygons




Raster / GRID data = shows geographic
features by way of arranged patterns
within a grid of square or rectangular
cells. The position of each cell is
determined by the number of its row and
column.
