Question 427Navigation General
70% to passWhich conic projection chart features straight lines which closely approximate a great circle?
A
Polyconic
B
Orthographic
C
Lambert conformal
D
Stereographic
AI Explanation
The correct answer is C) Lambert conformal. The Lambert conformal conic projection is a common chart used for coastal navigation, as it features straight lines that closely approximate great circle routes. This makes it well-suited for navigation, as great circle routes represent the shortest distance between two points on the Earth's surface. The other options are not as well-suited for this purpose - the polyconic and orthographic projections do not have this property of straight lines approximating great circles, while the stereographic projection is more commonly used for polar regions rather than general coastal navigation.
