base line
designated airspace over a piece of land. Like surface property, may be transferred. 153
air lots

benchmarks
a horizontal plane from which heights and depths are measured. 153

plat map
in a metes and bound legal description, the starting point of the survey, situated in one corner of the parcel; must follow the boundaries of the parcel to the point of ending, which is also the beginning. 145
point of beginning, POB
in a metes and bounds legal description, the ending point of the survey, which is also the point of beginning. 145
point of ending POE
ttthe main imaginary line running north and south and crossing a baase line at a definite point; used by surveyors for reference in locating and describing land under the rectangular (government) survey system of legal description. 146
principal meridian
a strip of land six miles wide, extending north and south nd numbered east and west according to its distance from the principal meridian in the rectangular (government) survey system of legal description. 146
range
a system established in 1785 by the federal government, providing for surveying and describing land by reference to principal meridians and base lines. 155
rectangular survey systems
a portion of township under the rectangular (government) survey system. it is a square with mile-long sides and an area of one square mile, or 640 acres. 155
section
the process by which boundaries are measured and land areas are determined; the on site measurement of lot lines, dimensions, and position of a house on a lot, including the determination of any existing encroachments or easements. 144

MATH SHORTCUT:
To calculate acres in a survey system description, multiply all the denominators and divide that number into 640 acres.
for instance, the SE1/4 of SE1/4 of SE1/4 of Section 1= 4x4x4=64;
640/64= 10 acres.
