Besavilla Cartography Practice Exam

Maximum error of area in Polyconic projection is:

5 7 3 9

Correct Answer:

Explanation:

In map projections, area distortion shows how much the projected area deviates from the true surface area. The Polyconic projection is not equal-area, so its areas are not preserved everywhere; distortion varies with latitude. The largest relative difference between projected area and actual area for this projection is about 7 percent. That means, at its worst, a region’s area on the map can be off by roughly 7% compared with its true area on the globe. This is why the correct choice corresponds to 7. Choosing much smaller values like 3% or 5% would underestimate the true maximum distortion, while 9% would overstate it for this projection.
