Land Surveying question n answers graded A+

Land SurveyingSurveying - correct answer the art of taking field measurements on or near the surface of the Earth Plane Surveying - correct answer ignores the curvature of the Earth for horizontal dimensions Geodetic Surveys - correct answer Curved (ellipsoidal) shape of the Earth Total Station - correct answer distances and angles (electronically), computation of x, y, z position and electronic storage of data. Theodolite - correct answer horizontal and vertical angles and alignment Error - correct answer The difference between a measured or observed value and the "true" value. Systematic Errors - correct answer Errors who's magnitude and algebraic sign can be determined. (can be eliminated form the measurement)(will compound if not fixed) Random Errors - correct answer Errors associated with the skill and vigilance of the surveyor. Precision - correct answer describes the degree of refinement with which the measurement is made. Accuracy - correct answer the relationship between the value of a measurement and the "true" value of the dimension being measured; greater the accuracy, smaller the error. Accuracy ratio - correct answer ratio of the error of closure to distance measured error of closure - correct answer difference between measured location and theoretically correct location
