1. Cartography is not part of GIS False
2. Most maps are wrong in at least three False
and sometimes four different ways.
As a GIS expert, you need to know
that your map or data can be ab-
solutely correct as long as you use
GPS data.
3. The curvature of the earth causes dis- False
tortion in all maps. If the area covered
in the map is small (personal or local
scale) the impacts of the curvature
are minimized. A study area that is
longer than approximately 63 miles
across is considered small enough to
not have any curvature impacts.
4. The "G" in GIS is not the most impor- True
tant term in the acronym, but without
the proper treatment of Geographic
components, GIS is not possible.
5. GIS is, for most part, a toolbox of True
functions that can be applied to any
discipline where the data have refer-
ence to space and time. GIS can be
implemented in Agriculture, Forestry,
Real Estate, meteorology, and space
exploration, among many other disci-
plines. The Weather Channel was an
early adopter of GIS technology.

6. Geographic Coordinate system (GCS) True
are regular measurements from the
center of the earth to a point on a
spheroid. The precision of a GCS lo-
cation is dependent upon the num-
ber of decimal places in the angu-
lar measurement and the precision of
the spheroid for the location of the
object.
7. A map projection is equal area if every True
part, as well as the whole, has the
same area as the corresponding part
on the Earth at the same reduced
scale. No flat map can be both equal
area and conformal.
8. In the context of GIS, Geography true
refers tot he science mathematical-
ly approximating the shape of the
earth. The science and math has be-
come more complex over time but
the formulas and concepts some-
times are traced to ancient geogra-
phers from the 1500's or earlier.
9. Latitude - Longitude coordinates are True
meaningless values unless the Spher-
oid is provided.
10. An orthographic projection is used to True
show the earth as it would appear
from deep space. This projection was
