Convert the angles of a triangle to radians and show a computational check: *(a) 39°41’54”, 91°30’16”, and 48°47’50” (b) 82°17’43”, 29°05’54”, and 68°36’23” 2.17 Why should a number 2 pencil not be used in field note keeping?
2.18 Explain why one number should not be superimposed over another or the lines of sketches. 2.19 Explain why data should always be entered directly into the field book at the time measurements are made, rather than on scrap paper for neat transfer to the field book later. 2.20 Why should the field notes show the precision of the measurements?
2.21 Explain the reason for item 18 in Section 2.11 when recording field notes. 2.22 Explain the reason for item 20 in Section 2.11 when recording field notes.
2.23 Explain the reason for item 12 in
Section 2.11 when recording field notes. 2.24 When should sketches be made instead of just recording data? 2.25 Justify the requirement to list in a field book the makes and serial numbers of all instruments used on a survey.
2.26 Discuss the advantages of survey controllers that can communicate with several different types of instruments. 2.27 Discuss the advantages of survey controllers. 2.28 Search the Internet and find at least two sites related to (a) Manufacturers of survey controllers. (b) Manufacturers of total stations. (c) Manufacturers of GNSS receivers.
2.29 How can survey controller data be stored? 2.30 What are the dangers involved in using a survey controller?
2.31 Describe what is meant by the phrase “field-to-finish.”
2.32 Why are sketches in field books not usually drawn to scale?
