Lab Exercise

Laboratory Exercise No. 11Higher Surveying bother: analytical METHOD OF PLOTTING CONTOURS Objective: To learn the analytical manner of insertion (or spacing) material body lines proportionally between points of known locations and elevations. science science laboratoryoratory EXERCISE OUTLINE A. INSTRUMENTS & ACCESSORIES : Triangles, straight edge, metric scale, divider, pencil, pen, eraser, tincture paper, cartolina, bilk or making tape, and electronic calculator. B. PROCEDURE : 1. This problem is an indorr lab get along which highlights a type of office/ compose work need in topographic mapping. It will be assumed that the granted data were taken from an actual theater of operations observation. 2. The lab instructor has the option to use the prep ard darta, revise it, or prepare a new set of data. 3. The ensuant tabulation gives elevations or points over the area of a 50m by 60m tract of land. The elevations were obtained by the gridiron method using 3-m squares. charge up 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 must(prenominal) whole be determined analytically. b. The contour map should be drawn on a grid layout (see accompanying field). whole essential map marginal information, elevation of points, labeling of horizontal and upright piano grid lines! , and etc. must likewise be indicated. c. work tracing paper with dimensions of at least 46 cm by 54 cm, and arrange the paper so the the longstanding 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
