  1. 1Short lines in a traverse are:
    1. ABetter than long lines because the ppm error in the EDM is smaller.
    2. BUndesirable because plumbing errors over short line cause large bearing errors.
    3. CBetter than long lines because angular errors become greater over long lines, thereby increasing the traverse misclose.
    4. DBest because it is easier for the surveyor and chainman to retain communication
    5. EUndesirable because the EDM additive constant error becomes too large.
  2. 2Pick which of the following angular readings would not be associated with a LF vertical angle reading of : -5° 10'.
    1. A275° 10'
    2. B-5.1667°
    3. C265° 10'
    4. D264° 50'
    5. E95° 50'
    6. F95° 10'
  3. 3Your chainman runs a total traverse and obtains a RF of 1 : 6,265. You calculate out their traverse sheet and find a total misclose 0.118m. If the misclose in the northing is 46mm, what is the misclose in the eastings? Show your answer in metres to 3dp. Do not show any units.

    Answer: [blank_start]0.109[blank_end]
    1. A0.109
  4. 4There are 3 main types of traverse specifications. One is the [blank_start][a][blank_end] traverse. This is typically used for [blank_start][b][blank_end] surveys. You might use an instrument with [blank_start][c][blank_end] accuracy of [blank_start][d][blank_end]". The expected RF would be 1 : 50,000 or better. Another type of traverse is the [blank_start][e][blank_end] accuracy type of traverse. This is typically used for [blank_start][f][blank_end] surveys. The instrument used could have an accuracy of greater than [blank_start][g][blank_end]". The RF would be better than 1 : 500 but less than 1: 5000. The third type of traverse is a [blank_start][h][blank_end] traverse. The instrument you would use would have accuracy's between [blank_start][i][blank_end]" and 10".

  5. 5Complete the following sentence concerning the calculation of the following traverse sheet -

    "The northing correction for line Trav 1 - Trav 2 is [blank_start][b][blank_end]m while the easting correction for this line is 0.00m. For the line Trav 3 - Trav 4 the northing correction is [blank_start][d][blank_end]m while the easting correction for this line is [blank_start][e][blank_end]m. The total misclose of this [blank_start][c][blank_end] traverse is [blank_start][a][blank_end]m."
