This course discusses various map knowledge, cartesian coordinate systems, as well as knowledge of tools used for measurement and mapping. This lecture also discusses how to measure longitudinal planes and profiles, as well as calculating height differences trigonometrically and crosshair height. The height difference calculation will produce a contour image so that the volume of both the fill and excavation in an earthwork can be determined. Apart from that, there is also material regarding mapping to measure the area of an area, including understanding azimuth and coordinates, open and closed polygons, and the position of points by tying them to the face. Lectures are held face-to-face, both directly and online. Assessments are carried out to determine the achievement of course learning outcomes through assignments, quizzes, mid-semester exams and final semester exams.
