When we cruise using variable (non-fixed) area points, it is very important to not "miss" a sample tree. Explain why this is important.

Fundamental of surveying

Please base your answer on the given choices and alos take note that this is not a graded question only a sample question thank you for the help

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.

Define Dispersion or Variability

The following data is given. DETERMINE SPOT HEIGHTS FROM CONTOURS i. Higher contour is 100.830 ii. Lower contour is 100.580 iii. Distance from higher contour to grid is 24 mm iv. Distance between contours is 34 mm

For a survey scale is given as 1 cm = 120 meter. If error in length measurement is and liming length of offset is 2 m then angle 8 is.

The interior angles X, Y, and Z of a triangular traverse were measured with the same precision. The results were as follows: Station Interior Angle No. of measurement X 410 3 Y 650 4 Z 750 2 Determine the most probable value of the interior angles.

What are the effects of Poisson?
