• Analyse Implications.
- "What if" scenario analysis
6. What is Spatial • Spatial data is data that has location at it's core;
Data? It can be in two, three or four dimensions (x,y,z,time)
X= latitiude

And time is time.
Haywood provides the examples of an avalanche at a ski slope. Its location is the
X and Y, its elevation from sea level (height up the mountain) is Z and its time of
occurrence is time.
7. What are some GPS
primary sources Survey
of spatial data Digitise
8. What are - Local Government
some secondary - State and Federal Government • Census
sources of spatial - Other organisations and businesses
data - ’Australian Spatial Data Directory
9. What is geodesy The study of the shape and size of the earth
10. What geodetic The World Geodetic System (WGS-84)
datum (position-
ing system) goes
gps use?
11. Define a geodetic Geodetic datums are reference systems that not only describe the size and shape of
datum the earth (ellipsoid), but also the origin and orientation of the coordinate systems
used to map the earth.
12. What positioning GDA94- a geocentric datum
system does Aus-
tralia use?
13. What is a geocen- A geocentric datum is one in which the point of origin is at the centre of the earth
tric datum?
14. What is a map The mathematical transformation of the earth's three dimensional surface to create
projection? a flat map.
