  8. Content • Definitions of Surveying and Surveyor • Figure of Earth • Types of Surveying • Units of Measurement • Scale of Surveys • Traditional Geometric Principles of Surveying

  9. Definitions • Surveying • Art and science of making and analyzing measurements made on, above or below the surface of the earth, and the processing of these measurements into some positional formsuch as maps and coordinates. It also includes the opposite establishment of positions on earth that previously located on a plan or a map.

  10. Definitions • Surveyor • A professional person with the academic qualifications and technical expertise to practice the science of surveying.

  11. Definitions • Surveyor can be enrolled within the following practices: • Determination of size and shape of any part of earth surface. • Positioning of objects in space. • Determination of boundaries. • Establishment of LIS and GIS • Measurement of natural resources • Planning of Properties • Value Assessment • Estimation of Construction Costs

  12. Figure of Earth

  13. Geoid System

  14. Geoid System • The following system is used for reference: • For areas > 500 km2 Ellipsoid • a = 6378135 m • b = 6356750.5 m • f = 1/298.26 • e = 0.08181881066 • 50 km2 < Area < 500 km2 Sphere • R = 6372200 m • Area < 50 km2 Plane

  15. Types of Surveying • Size of Surveying: • Geodetic Surveying • Plane Surveying • Positioning of objects in space. • Ground Surveying • Remote Surveying

  16. Types of Surveying • Purpose of Surveying: • Land Surveying • Topographic Surveying • Hydrographic Surveying • Route Surveying • Construction Surveying • Mine Surveying

  17. Questions?!

  18. Units of Measurement • Length: • English System inch (in “), foot (ft ‘), Yard (yd) • Metric System cm, m, km • Area: • English 1 acre = 43560 ft • Metric 1 donum = 1000 m2 • 1 hectare = 10000 m2 • 1 km2 = 1,000,000 m2

  19. Units of Measurement • Angles: • Sexagesimal • circle is divided into 360°, each is divided into 60 min (΄), each is divided into 60 seconds (΄΄) • 213° 24΄ 47΄΄

  20. Units of Measurement • Decimal or Centisimal • circle is divided into 400 equal grads (g), each grade is divided into 100 simal minutes (c), each is divided into 100 centisimal (cc) • 128g 60c 47cc

  21. Units of Measurement • Decimal or Centisimal • The central angle opposite to a circular arc whose length is equal to its radius. • The whole circle has an opposing angle 2π

  22. Scale of Surveys • Architectural Works, Building Works, Location Drawings: • 1/50, 1/100, 1/200 • Site Plans, civil engineering works: • 1/500, 1/1000, 1/1250, 1/2000, 1/2500 • Town surveys, highway surveys: • 1/1250, 1/2000, 1/2500, 1/5000, 1/10000, 1/20000, 1/50000 • Mapping: • 1/25000, 1/50000, 1/100000, 1/200000, 1/500000, 1/1000000
