Study Notes
Introduction to Land Surveying
- Land surveying involves measuring distances and angles to determine the relative positions of points on the Earth’s surface.
- This practice utilizes various techniques and instruments for accurate data collection.
Purposes of Land Surveying
- Essential for determining property boundaries, land development, and construction projects.
- Provides legal documentation and assists in land ownership disputes.
Branches of Land Surveying
- Cadastral Surveying: Involves mapping property lines for legal documentation, often using GPS for boundary determination. Cadastral plans must show adjacent plots and access roads.
- Engineering Surveying: Focused on infrastructure projects (roads, buildings), emphasizes high accuracy over short distances. Typically does not consider Earth's curvature.
- Topographic Surveying: Determines the location of natural and artificial features, producing topographic maps that depict elevation and feature positions using conventional symbols and contours.
- Hydrographic Surveying: Studies bodies of water, mapping underwater terrain and features.
- Geodetic Surveying: Accounts for Earth's curvature, providing broader measurements for large-scale geographic mapping.
Coordinate Systems for Survey Computations
- Utilizes the rectangular coordinate system for defining points, enabling precise calculations and mapping.
Basic Principles and Techniques of Surveying
- Working from the Whole to the Part: Begin with broad measurements before focusing on specific details.
- Appropriate Method for Required Result: Selecting the best method applicable to the survey objectives.
- Sectioning: Techniques for capturing detailed configurations of land contours.
Importance of Surveying Theory
- Students should grasp key surveying principles, including chain, compass, theodolite, and EDM instrument techniques for measuring angles and distances.
- Understanding the theoretical framework supports practical skills in conducting land surveys.
Chain/Tape Surveying Equipment
- Arrows/Pins: Used for marking chain lengths with one end pointed; aids in accurate distance measurement.
- Tapes: Made from various materials; used for subsidiary measurements and offsets. Steel tapes are preferred for accuracy.
- Ranging Poles: Mark main survey points and intermediate locations; available in various lengths for convenience.
Survey Documentation
- Field notes and maps require clear recording practices to ensure unambiguous interpretation by others.
- Conventions, such as the use of a plus sign for certain measurements, help distinguish between different types of data collected during surveys.
