1 Chapter 1 Introduction of Basic Surveying What is Surveying? Surveying has to do with the determination of the relative spatial location of points on or near the surface of the earth. It is the art of measuring horizontal and vertical distances between objects, of measuring angles between lines, of determining the direction of lines, and of establishing points by predetermined angular and linear measurements. Along with the actual survey measurements are mathematical calculations. Distances, angles, directions, locations, elevations, areas, and volumes are thus determined from the data of the survey. Survey data is portrayed graphically by the construction of maps, profiles, cross-sections, and diagrams. Aqueduct in Spain Pyramid in Egypt

2 Types of surveys: 1. Geodetic Surveying: - The type of surveying that takes into account the true shape of the earth. - These surveys are of high precision and extend over large areas. 2. Plane Surveying: - The type of surveying in which the mean surface of the earth is considered as a plane (in which its spheroidal shape is neglected) with regard to horizontal distances and directions. - Measurements are made as if the lines of force due to gravity were everywhere parallel to each other, as if underneath the irregular ground surface there existed a flat, horizontal reference plane.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
