What is the disadvantage in using a
Mercator projection for surveying
purposes?
1.
2.
3.
4.
Mercator projections of the
equatorial regions are
impossible
Mercator projections provide
relatively large-area maps that
are conformal in distance only
The parallels are slightly
curved. They are neither
parallel nor precise
No distance scale can be
consistently applied to all
parts of the Mercator
projections
8-55.
A polyconic projection has near
conformal direction due to what
factor?
1.
Largs-area maps are projected
onto several cones and the
spliced together
2.
Small-area maps are projected
onto several cones and built
around a central meridian
3.
Small-area maps are projected
on more than one cone to have
parallel meridians
4.
Small-area maps are projected
on more than one cone to have
parallels perpendicular to
meridians
8-56.
Which of the following statements
regarding great circles are true?
1.
All parallels are great circles
2.
All meridians are great circles
3.
The equator is a great circle
4.
Both 2 and 3 above
8-57.
A nautical mile is equivalent to
1.
1 minute of longitude
2.
1 minute on an arc on a great
circle
3.
1 minute of latitude
4.
Both 2 and 3 above
8-58.
What map projection is used as a
base for the state coordinate
systems for zones whose greater
dimension is north-south?
1.
Transverse Mercator projection
2.
Lambert conformal conic
projection
3.
Polyconic projection
4.
Gnomonic projection
