Suggest a reason why this would be included on. One is geographic north, and the other is magnetic north. Hint: A contour interval in the survey about the vertical distance or sometimes as the difference in its elevation. contourfcmap(x,y,z,clev,cmap) plots a filled contour plot of the matrix z with coordinates x and y.z must be at least a 2x2 matrix x and y can either be matrices defining the grid for z, or vectors that correspond to the column and row coordinates, respectively. On the bottom margin, there are two arrows together. At each corner is a longitude and latitude number. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing. What is the contour interval of this map Observe the numbers at each corner of the map area. Index contours are bold or thicker lines that appear at every fifth contour line. To determine the height of the instrument, subtract the backsight reading from the benchmark elevation subtract the foresight reading from the benchmark elevation add the backsight reading to the benchmark elevation add the foresight reading to the benchmark elevation A contour interval is the vertical distance or difference in elevation between contour lines. is the distance of the theodolite above the leveling datum of the target above sea level of the level above sea level of the theodolite above the point/benchmark Identify the following feature of the digital theodolite, as referenced by the red arrow: SOU Optical image Focus Horizontal Lock & Fine-tune Adjustment Gun Sight Cross-hair Focusģ:4:5 is a method of Triangulation survey Making perpendicular offset Levelling none of these.įace right and face left observations eliminate the graduation errors eccentricity error observational errors none of these If the leveling screw is turned as shown, then the bubble in the level will move in the direction of the arrow. contour interval synonyms, contour interval pronunciation, contour interval translation, English dictionary definition of contour.
The height of a Tee-beam above the floor level is: m Tee Beam Floor Datum The reading on a staff held upside down against the underside of the beam is 3.565 m. A contour interval is a vertical distance or a difference in elevation between contour lines in a topographic map, index contour lines are bold or thick.Scale of the map: For small scale maps covering. The staff reading on the floor is 2.055 m. The Edit Intervals dialog box appears with a default set of contour intervals that you can modify in any of the following ways: Edit any interval value by clicking its row and entering a new value. A contour interval is a vertical distance or difference in elevation between contour lines. To customize interval values for the User-defined interval type, click. The elevation of the floor is 100.855 m above datum. Select User-defined to use a customized set of values in the contour plot. What is the process of spacing the contours proportional between the plotted ground points? Interpolation Tacheometric method Cross section method By squares method Transcribed image text: Contour interval is inversely proportional to the scale of the map directly proportional to the flatness of ground larger for accurate works larger if the time available is moreĬontour lines cross a ridge line at 90° 100° 45° 30°
