Study Notes
Introduction to Surveying
- An ancient art and science focused on determining angular and linear measurements.
- Aims to establish form, extent, and relative position of points, lines, and areas on the Earth's surface or extraterrestrial bodies.
- Utilizes applied mathematics and specialized equipment.
Classifications of Surveying
-
Plane Surveying
- Assumes the Earth is flat for limited extent distances.
- Exact shape of the Earth is disregarded.
-
Geodetic Surveying
- Accounts for the Earth's spheroidal shape over larger areas.
- High precision using geodesical principles; utilizes advanced mathematics including spherical trigonometry and calculus.
Types of Surveys
-
Cadastral Surveys
- Closed surveys determining property lines, boundaries, and municipal jurisdictions.
-
City Surveys
- Focus on urban areas for planning, locating property lines, and mapping physical features.
Field Survey Party Roles
-
Chief of Party
- Responsible for the overall direction and supervision of the survey.
-
Assistant Chief of Party
- Aids the chief and assumes responsibilities in their absence.
-
Instrumentman
- Operates and maintains surveying instruments.
-
Technician
- Manages electronic instruments and equipment calibration.
-
Computer
- Carries out computations of survey data and computational checks.
-
Recorder
- Documents sketches, measurements, and schedules.
-
Head Tapeman
- Oversees accurate linear measurements using tape and marking stations.
-
Rear Tapeman
- Assists the head tapeman during measurements.
-
Flagman
- Holds markers and assists with measurements; clears obstructions.
-
Rodman
- Holds the stadia or leveling rod for measurements.
-
Pacer
- Verifies linear measurements made by the tapeman.
-
Axeman/Lineman
- Clears vegetation and ensures safety on-site.
-
Aidman
- Provides first aid to survey team members.
-
Utilityman
- Assists with logistical needs like driving and setting up camp.
Types of Measurement Errors
-
Personal Errors
- Result from human limitations in senses; varies by individual.
-
Natural Errors
- Caused by environmental factors like temperature, humidity, and magnetic declination.
Accuracy and Precision
-
Accuracy
- Measures how close a result is to its true value.
-
Precision
- Reflects the consistency of repeated measurements and their clustering.
Theory of Probability
-
Probability indicates the likelihood of an event occurring, relevant in scientific measurements.
-
Most Probable Value (MPV)
- The average of repeated measurements reflects the expected result.
Relative Precision (RP)
- Defined as the ratio of error to measured quantity, expressed in the same units to facilitate comparisons.
