SURVEYING
As stated by Dr. Adam Chrzanowski, "Surveying is the field of applied science and engineering that deals with spatial information about positions of points on, above or below the earth's surface. The spatial information may be displayed as maps, digital terrain models, or just a list of coordinates of the points of interest in a selected coordinate system. "
The purpose of this courseis to learn; how to make field notes, basic surveying procedures and the instruments used to perform these procedures, survey calculations that apply to the procedures and how the survey procedures apply to mining.
Main Types of Surveys
Plane surveying is that type of surveying in which the surface of the earth is considered to be a plane for all X and Y dimensions. All Z dimensions (height) are referenced to the mean spherical surface of the earth (mean sea level).
Geodetic Surveying is that type of surveying in which the surface of the earth is considered to be spherical (actually an ellipsoid of revolution) for X and Y dimensions. The Z dimensions (height) are referenced to the mean surface of the earth (msl),
Classes of Surveys
Preliminary: to locate and gather survey data, physical features and vertical information.
Layout: marking on the ground the features shown on the design plan ie; roads, pipelines.
Control: used to reference preliminary and layout surveys. Horizontal control is tied to the property boundaries or other horizontal control points and vertical control is determined by benchmarks with known elevation amsl.
