APPENDIX  III SAMPLE SURVEY FIELD NOTES The  field  notes  contained  in  this  Appendix  are presented to show you, the EA2 survey party chief or the  EA1  supervisor,  how  a  series  of  notes  are  indexed and arranged in a field notebook For completeness, the field notes shown in appendix V of the EA3 TRAMAN are repeated in this Appendix. The field notes in this Appendix are samples of the types of notes that are kept in surveying. They are not intended to describe how the notes should be kept. That is up to you. You are the one who decides what minimum information  is  necessary  to  achieve  complete  notes,  and you are the one who decides how that information is to be recorded. As you are well aware, note keeping is not only an art that makes your notes clean and legible but it is also a science that makes your notes meaningful and correct. Figures AIII-1 and AIII-2 are samples of the front page and index of a notebook. The front page should be filled out as required by your unit. A separate book should,  when  possible,  be  kept  for  each  major  project. The  index  should  show  all  surveying  projects  by  page number and must be kept up-to-date at all times. An example of recording horizontal measurements is shown in figure AIII-3. To record taping problems, record  distance  measured  (by  parts  of  tapes,  if measured) going from one station to the next. Record in the direction in which measured; that is, down for forward  measurements,  up  for  backward  measure- ments. A page check of a direct-level circuit is shown in figure AIII-4. As you recall, when page checking you are determining that the difference between the sum of the backlights and the sum of the forsights is equal to the   difference   in   elevation   between   the   initial benchmark or turning point and the final benchmark or turning point. For direct-level notes exceeding one page, the page check should always be made for each separate page of the notes. The final page should, in addition, show also a check from start to finish of the entire circuit. Remember, too, that when making a page check, you are checking only the accuracy of the arithmetic, not the accuracy of the level shots. Figure AIII-5 shows horizon closure for a traverse station. In this example, each angle was repeated twice, once direct and once reverse, using the procedures you studied  in  chapter  13  of  the  EA3  TRAMAN  for measuring  angles  by  repetition. Turn all angles, direct and reverse, to the right. Enter means, and if mean does not match single reading to ±30", reshoot the angles. Never proceed to the next station  until  horizon  closure  (360°  ±30")  has  been achieved. Figures AIII-6 and AIII-7 show, respectively, notes for  a  station-angle  traverse  and  a  deflection-angle traverse. Figure AIII-1.—Front page of a notebook. AIII-1
