Lamberts Projection

Question 1

Parallel of origin of a conical chart

Answer 1

The circle of tangency would be a parallel of latitude - a small circle

Question 2

Parallels of latitude on a conical

Answer 2

Curved arcs of concentrated circles unequally spaced

Question 3

Meridians on a conical

Answer 3

Straight lines converging at the poles

Equally spaced

Question 4

Convergence

Answer 4

Convergency = CHlong x sinPO

Question 5

Sin Parallel of Origin

Answer 5

Convergence factor

Constant of the cone “n”

CF

Question 6

Lambert’s Conformal

Answer 6

Cone cuts through the earth

2 standard parallels at east <= 16* apart

Increases the area of constant scale

Question 7

Scale

Answer 7

Scale expands outside the standard parallels, and contracts in between the two standard parallels.

Question 8

Rhumb Lines

Answer 8

RHUMB LINES are curved,

concave to the pole
and
convex to the equator

Question 9

Great Circles

Answer 9

• Approximate straight lines, -

- Curves CONCAVE to the pole of projection

Question 10

Earth convergency is most accurately represented at:

Answer 10

Parallel of Origin

Question 11

The parallels on a Lambert Conformal Conic chart are represented by:

Answer 11

Parallels of latitude are concentric circles centred on the Pole and shown as such on a Lamberts chart.
