Answer 13

arrangement

Question 14

Advance planning and proper field procedures are necessary to ensure clarity of sketches and tabulations, and to minimize the possibility of mistakes and omissions.

Answer 14

clarity

Question 15

A good sketch will help to convey a correct impression. They are drawn freehand and of liberal size. The student should note that a sketch crowded with unnecessary data is often confusing.

Answer 15

sketches

Question 16

A series of numerical values observed in the field are best shown in a tabulated format. This format prevents mistakes, allows easy checking, save time, make the calculation legible to others, and simplify the work of the person checking the field notes.

Answer 16

Tabulations

Question 17

provide a written description of what has been done in the field.

Answer 17

explanatory notes

Question 18

Calculations of one kind or another form a large part of the work of surveying. Most surveying-type computations are made algebraically by the use of simple arithmetical steps and trigonometric functions.
