13 Surveying Field Notes - Permanent legal record of field work - Notes must be complete and correct. - All notes must be written in the field book to provide experience under job conditions - Notes with a pencil of at least 3H hardness - Erasures are not permitted, use a line and correct above. For pages use diagonal lines. - Never remove pages from the field book

14 Arrangement of Notes - Left and right hand pages used in pairs ALWAYS!!! - One title using both pages - Location and type of work on right page beneath the title - Left page is ruled in 6 columns and normally reserved for tabulations - Upper left hand corner of the right page should contain: Date, time, wind, velocity, temp, etc. - Upper right hand corner of the right page should contain: Names of the party, their duties and instruments serial codes.

15 Suggestion on Recording Notes Take Care of Instruments Attendance Policy ADA Academic Integrity Dropping the Course

16 CONTENT - Objectives - Equipment - Procedure Pacing - Procedure Taping

17 - Pacing, a rapid means of approximately checking more precise measurements and taping - Taping, measuring horizontal or inclined distances with a steel tape

18 - 100 foot tape - One range/alignment pole - Chaining pins - Wooden hub - Hammer

19 - Pacing is a rapid means of approximately checking more precise measurements of distance - Pacing over rough country may be done with a precision of one in one hundred - The natural pace of each individual normally varies from 2 ½ to 3 ft

20 - Each member will determine his/her pace - Walk with normal steps back and forth over the 300 foot measured distance adjacent to the EE building - Divide the 300 feet by the average of number of steps - Pace off three times and average the number of steps

21 - The common method of determining distance is by direct measurement with a tape - The tape is called a "chain" and is usually 100 ft in length - The distance measured with a steel tape is much more precise than the distance obtained by pacing - The precision obtained depends upon the degree of refinement with which the measurements are taken - Ordinarily, taping over flat, smooth ground with a steel tape or chain, divided in hundredths of a foot, provides a precision of one in three thousand to one in five thousand

22 - Select a flat open area - Place a wooden hub 200 feet from the starting point (Pace off) - Each hub with the group letter - Measure the distance between hubs twice - Use chain pins to mark intermediate points - Use range poles to maintain alignment of the tape
