2.21 Explain the reason for item 7 in Section 2.11 when recording field notes.
2.22 Explain the reason for item 13 in Section 2.11 when recording field notes.
2.23 Explain the reason for item 18 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.
