Louisiana has how many baselines and meridians?

• A. One baseline and one meridian
• B. Two baselines and two meridians
• C. Three baselines and two meridians
• D. One baseline and two meridians

Answer: (D)

In land surveying under the Public Land Survey System, land is described using a grid built from a baseline (an east–west reference) and meridians (north–south references). The number of baselines and meridians a state uses depends on its surveying history and geography.

Louisiana uses one baseline for the entire state, and two meridians to cover the area. This setup reflects how the land was originally mapped in pieces under different authorities or survey needs, but ultimately fits into a single east–west reference with two north–south lines. So parcels in the state are described relative to that single baseline plus whichever of the two meridians applies to their location.
