coordinate for a location. How
accurately have you located this
point?
1.
Within a 1000-meter square
2.
Within a 100-meter square
3.
Within a 10-meter square
4.
Within a 1-meter square
8-49.
Figures 9-18 and 9-19 show some of
the marginal information of the
frid map. Which of the following
items are part of the marginal
information?
1.
Index to state boundaries
2.
Latitude and longitude of the
SW corner of the grid map
3.
Both 1 and 2 above
4.
Grid north
Learning Objective: Identify
concepts of conic, gnomonic, and
polyconic projections. Recognize
characteristics of conformality.
8-50.
In figure 9-20, what point is the
apex of the cone?
1.
North Pole
2.
South Pole
3.
Equator
4.
30th parallel
8-51.
What is the difference between a
gnomonic projection and a conic
projection of the polar region?
1.
In the gnomonic projection, the
cone is cut and flattened out
to form a map; whereas, the
conic projection will appear as
is
2.
In the gnomonic projection, the
points lying close together on
either side of the meridian
along which the cone is cut
will be widely separated on the
map; whereas, the conic
projection will give a
continuous and contiguous view
of the area
3.
In the conic projection, the
cone is cut and flattened out
to form a conformal map;
whereas, the gnomonic
projection will appear as is
4.
In the conic projection, the
cone is cut and flattened out
to form a map; whereas, the
gnomonic projection will appear
as is
8-52.
A Mercator projection is useful as
a navigational chart due to which
of the following factors?
1.
Directional conformity only
2.
Distance conformity only
3.
Distance and directional
conformity
4.
Distance conformity and near
directional conformity
8-53.
Conformity for projections meets
which of the following
descriptions?
1.
Meridians are parallel to each
other and equidistant from
parallels
2.
Direction is relative to the
point occupied
3.
Distance is proportional to the
location
4.
Distance scale is the same for
north and south as east and
west
