Statement (I): Dynamic surveying implies some sort of motion. It allows user to move during surveying and to collect data on move. Statement (II): Rapid static surveying technique, also known as fast static technique, is much like static surveying except that the occupation times are longer.
- ABoth Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
- BBoth Statement (I) and Statement (II) are individually true but Statement (II) is not the correct explanation of Statement (I)
- CStatement (I) is true but Statement (II) is falseCorrect
- DStatement (I) is false but Statement (II) is true
Solution
Concept
Static, rapid static and kinematic GPS surveying
Step-by-step solution
1. Dynamic (kinematic) surveying allows the receiver to move while collecting data (Statement I true). 2. Rapid (fast) static surveying is like static surveying but the occupation times are SHORTER (Statement II false).
Explanation
Rapid static reduces the observation time per station, which is why it is called fast static.
Why the other options are wrong
II claims longer occupation times, which is the opposite of the technique.
Shortcut
Rapid static = shorter occupation.
Common mistake
Accepting "longer".
Correct answer: C) Statement (I) is true but Statement (II) is false
