Laboratory Exercise No. 11Higher Surveying bother: analytic METHOD OF PLOTTING CONTOURS Objective: To learn the analytical manner of interpellation (or spacing) shape lines proportionally between points of known locations and elevations. science science science lab EXERCISE OUTLINE A. INSTRUMENTS & ACCESSORIES : Triangles, straight edge, metric scale, divider, pencil, pen, eraser, tincture paper, cartolina, itch or making tape, and electronic calculator. B. PROCEDURE : 1. This problem is an indorr lab get along which highlights a type of office/ draftsmanship work need in topographic mapping. It will be assumed that the granted data were taken from an actual matter observation. 2. The lab instructor has the option to use the prep bed darta, fiat it, or prepare a new set of data. 3. The accompany tabulation gives elevations or points over the area of a 50m by 60m tract of land. The elevations wer e obtained by the gridiron method using 3-m squares. manoeuvre 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 moldiness whole be determined analytically. b. The contour map should be drawn on a grid layout (see accompanying skeleton). all essential map marginal information, elevation of points, labeling of horizontal and tumid grid lines, and etc. must likewise be indicated. c. recitation tra cing paper with dimensions of at least 46 cm! by 54 cm, and arrange the paper so the the lengthy situation is vertical. d. Indicate the elevations of the following office contours: 1300, 1400 ad 1500m. the burdensomeness 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:
