Basic Surveying II

Upon completion of this course, students should be able to: 1. carryout measurements, apply necessary corrections to attain required accuracy; 2. use more advanced methods of surveying and geoinformatics tools for data acquisition and data processing; and 3. demonstrate understanding of elementary adjustment of survey network and production of plans/maps at suitable scales.

Field observations, Forward, Backward and area computations in traversing. Elementary adjustment of traverse network. Production of traverse plan at a suitable scale. Sources of errors and accuracy attainable in traversing. Basic concept, method and uses of leveling. Leveling with inverted staff, double and reciprocal leveling. leveling data collection, computation and elementary adjustment of level network. Sources of errors, corrections and accuracy attainable in leveling. Principles, special features and uses of tachometry. Field observations, computations and production of plans at suitable scales from tachometry. Substance bar and its uses.
