Lab Exercise

Laboratory Exercise No. 11Higher Surveying bother: analytical METHOD OF PLOTTING CONTOURS Objective: To learn the analytical manner of interpellation (or spacing) course lines proportionally between points of known locations and elevations. science testing ground EXERCISE OUTLINE A. INSTRUMENTS & ACCESSORIES : Triangles, straight edge, metric scale, divider, pencil, pen, eraser, tincture paper, cartolina, cut across or making tape, and electronic calculator. B. PROCEDURE : 1. This problem is an indorr testing ground get along which highlights a type of office/ pen work need in topographic mapping. It will be assumed that the granted data were taken from an actual field of view observation. 2. The lab instructor has the option to use the prep ared darta, rescript it, or prepare a new set of data. 3. The attach to tabulation gives elevations or points over the area of a 50m by 60m tract of land. Th e elevations were obtained by the gridiron method using 3-m squares. superman A-1 is located at the northwest corner of the lot and pont G-6 at the southeast corner. each(prenominal) elefations are in meters. 4. The requirements for this lab exercise are: a. trace a contour map using a level scale of 1:125 with a contour breakup of 20 meters.

The proportional spacing of contour lines essential whole be determined analytically. b. The contour map should be drawn on a grid layout (see accompanying subject). entirely essential map marginal information, elevation of points, labeling of h orizontal and vertical grid lines, and etc.! must likewise be indicated. c. put on tracing paper with dimensions of at least 46 cm by 54 cm, and arrange the paper so the the eternal situation is vertical. d. Indicate the elevations of the following office contours: 1300, 1400 ad 1500m. the heaviness of these index contours should be drawn heavier than the intermediate contours. Rfer to the illustrative sketch shoen below. e. A total of 450 grid squares, as...If you want to get a wax essay, order it on our website: OrderCustomPaper.com
