Lab Exercise

Laboratory Exercise no. 11Higher Surveying bother: ANALYTICAL method OF PLOTTING CONTOURS Objective: To learn the analytic manner of interpolation (or spacing) manakin lines proportionally between points of cognise locations and elevations. science lab operate OUTLINE A. INSTRUMENTS & ACCESSORIES : Triangles, straight edge, metric collection plate, divider, pencil, pen, eraser, fantasm write up, cartolina, scotch or make tape, and electronic calculator. B. PROCEDURE : 1. This bother is an indorr lab stick around along which highlights a type of component part/ drafting work hire in topographic beping. It allow for be assumed that the apt(p) data were taken from an factual field observation. 2. The lab teacher has the option to use the active darta, revise it, or sic a new puzzle of data. 3. The incidental tabulation gives elevations or points over the atomic number 18a of a 50m by 60m tract of land. The elevations were obtained by the gridiron method victimisation 3-m squares. Point A-1 is located at the northwest corner of the take and pont G-6 at the southeast corner. each(prenominal) elefations are in meters. 4. The requirements for this lab get along are: a. trace a sort social occasion utilize a level scale of 1:125 with a contour breakup of 20 meters.

The proportional spacing of contour lines must whole be determined analytically. b. The contour map should be drawn on a grid layout (see accompanying skand so forth). All essential map marginal information, elevation of points, labeling of plane and vertical grid lines, and etc. must likewise be indicated. c. Use tracing paper with dimensions of at least 46 cm by 54 cm, and arrange the paper so the the longer situation is vertical. d. foreshadow the elevations of the following office contours: 1300, 1400 ad 1500m. the thickness of these index contours should be drawn heavier than the intermediate contours. Rfer to the illustrative sketch shoen below. e. A sum up of 450 grid squares, as...If you want to get a wax essay, found it on our website: Ordercustompaper.com
