2. The interior angles of a closed traverse were measured with the following results: A= 110° 35' , B = 59° 52' , C = 85° 05' , D = 70° 20' , and E = 213° 53'. Determine the error of closure and adjust the measured angles. Assume that the error of closure was primarily due to accidental errors. Tabulate values accordingly.
Which among traverse adjustment methods can be used to evaluate data with equal angular and linear accuracy? Select the correct response(s): Crandall Method Transit Rule Least squares method Equilibrium Method Bowditch Rule
C) A 20-mile strip of terrain is to be photographed for highway mapping. The aerial camera to be used has a lens of focal length 12 in and takes 9×9 inches photographs. The ground elevation varies from a low of 800.00 ft to a high of 1050.00 ft above mean sea level. The plane has to make one flight line and the average width of the photographic coverage is to be 1650.00 ft. What will be the average scale of the photographs? What flying height, above mean sea level, should be used for this flight? If it is specified that the overlap (end lap) between photos be 60% and that 2 extra exposures be added at each end of the flight line, find how many photographs will be required.
a. Given the following tabulated data for a closed traverse in which the lengths of BC and CD have not been measured in the field. Determine these unknown quantities.b. Determine the actual area of the given traverse above using any method that you prefer.
An upright aerial photograph is taken using a camera focal length of 150.7 mm, where there are 2 points, namely a and b, whose photo coordinates have been calculated with the results as in the following.Xa = 18.4 mm ; Yes = -61.4 mmXb = 110.1 mm ; Yb = -21.2 mmFurthermore, the height of the two points is calculated in the field, namely point A (437.5 m) and point B (444.9 m). If the distance between points A and B is 585.1 meters, what is the flying height of the plane when shooting?

vertical aerial photo is exposed at 3910 ft above mean sea level using a camera having an 88.9 mm focal length. A triangular parcel of land that lies at elevation 850 ft above sea level appears on the photo, and its sides measure 39.5 mm, 28.9 mm, and 27.7 mm, respectively. What is the approximately area of this parcel in acres? 3. On a vertical photograph, image a and b of ground points A and B have photographic coordinates X = -12.68 mm, Ya = 70.24 mm, Xo = 89.07 mm, and yo = 92.41 mm. The horizontal distance between A and B is 1317 m, and the elevation of A and B are 382 m and 431 m above datum, respectively. Calculate the flying height above datum if the camera had a 152.5 mm focal length?
