| 8. | A staff reading taken on a point whose elevation is to be determined as on a change called ? | |
|
fore sight reading
|

| 9. | The plane table surveying is ? | |
|
most suitable for preparing small-scale maps
|
||
|
particularly advantageous in magnetic areas
|
||
|
less costly than a theodolite survey
|
||
|
all of the above
|
||
| 10. | Which of the following statement is correct ? | |
|
The error in measured length due to bad ranging is compensating error.
|
||
|
If the chain used in measuring a distance is too short, the error is positive error.
|
||
|
The error in measured length due to careless holding of chain is cumulative error.
|
||
|
When the pull applied while measuring with a tape, is more than the standard tape, the error in measured length is positive.
