Government Survey System

The government or rectangular survey system divides land using principal meridians, baselines, townships, ranges, and 36 one-mile-square sections. A township is generally six miles by six miles. A section is generally 640 acres, and fractional section descriptions are solved by repeatedly multiplying the stated fractions.

Facts checked against the current PSI Candidate Information Bulletin and GREC sources. Last reviewed August 2, 2026. Editorial standards.

The Rule

PSI publishes the weight for the complete content area, not a fixed question count for this lesson. Learn the rule well enough to apply it when PSI changes names, numbers, or parties in a new scenario.

Complete lesson

Read each concept as part of one decision system. The exam often gives one accurate statement and three statements that belong to a nearby concept.

Principal meridian and baseline

North-south meridians and east-west baselines create the reference framework from which township and range positions are counted.

Township and range

Township tiers run north or south of a baseline. Ranges run east or west of a principal meridian. Their intersection identifies a survey township.

Sections

A standard township contains 36 numbered sections. Each standard section is one square mile or 640 acres, subject to survey corrections.

Fractional descriptions

Work from the section inward. The NW 1/4 of the SE 1/4 is 1/4 × 1/4 × 640, or 40 acres.

Decision rule

Start with 640 acres for a standard section and multiply every fraction named in the description.

Georgia-specific distinction

Georgia is not a primary rectangular-survey state, but PSI includes the method on the national outline. Learn it as national exam vocabulary and do not assume it is the usual Georgia deed form.

Worked example

Scenario. Find the acreage in the E 1/2 of the NW 1/4 of a standard section.

Reason it through. Start with 640 acres, multiply by one-fourth, then by one-half: 640 × 1/4 × 1/2.

Answer. The parcel contains 80 acres.

Common exam traps

  • Treating a township as one square mile
  • Adding fractions instead of multiplying
  • Forgetting range is east or west
  • Assuming every surveyed section is perfectly regular

Original practice questions with detailed explanations

These questions were written for instruction and mapped to the current outline. They are not copied from PSI or any live examination. Choose an answer before opening the explanation.

Question 1

How many acres are in a standard section?

  1. A. 40
  2. B. 160
  3. C. 640
  4. D. 3,600
Show answer and explanation →

Answer: C. 640

One standard section is one square mile, equal to 640 acres.

Question 2

A standard township is generally how large?

  1. A. One mile by one mile
  2. B. Six miles by six miles
  3. C. Ten miles by ten miles
  4. D. Thirty-six miles by thirty-six miles
Show answer and explanation →

Answer: B. Six miles by six miles

A survey township is six miles square and contains 36 sections.

Question 3

How many acres are in the SW 1/4 of the NE 1/4 of a section?

  1. A. 20
  2. B. 40
  3. C. 80
  4. D. 160
Show answer and explanation →

Answer: B. 40

640 × 1/4 × 1/4 = 40 acres.

Government Survey System questions

Facts checked against the current PSI Candidate Information Bulletin and GREC sources. Last reviewed August 2, 2026. Editorial standards.

Is Government Survey System on the Georgia real estate exam?

Yes. It belongs to PSI's Property Ownership content area, which is 10% of the 100-question national portion. PSI publishes content-area weights, not a guaranteed question count for this individual lesson.

What is the main rule for Government Survey System?

Start with 640 acres for a standard section and multiply every fraction named in the description.

What Georgia-specific distinction should I remember?

Georgia is not a primary rectangular-survey state, but PSI includes the method on the national outline. Learn it as national exam vocabulary and do not assume it is the usual Georgia deed form.

How do I know I have mastered this lesson?

Explain the rule without notes, solve the worked example again with changed facts, answer all original questions correctly, explain every distractor, and repeat mixed practice on a later day.
