What does a Base Line refer to in surveying?

  1. A line running north-south

  2. The main imaginary line running east and west

  3. A reference line for local sections

  4. A line marking county boundaries

The correct answer is: The main imaginary line running east and west

A Base Line in surveying specifically refers to the primary imaginary horizontal line that runs east and west. This line is fundamental in the public land survey system (PLSS) and serves as a reference point from which measurements and boundaries in a given area are calculated. It helps establish the coordinates of parcels of land and provides a framework for dividing land into sections and townships. By having a consistent horizontal reference, surveyors can accurately describe the position and extent of land parcels in relation to the Base Line, facilitating land ownership and management. It is essential for delineating large tracts of land and ensuring uniformity in surveying practices.
