FIXED TRAVERSE
Set the instrument in the order of 1, 2, 3 and 4,
then make the measurement.
1: [Start point]
2 and 3: [Traverse points of Station P]
4: [End point]
CLOSED TRAVERSE
Set the instrument in the order of 1, 2, 3 and 4,
then make the measurement.
1:[Start point]
2, 3, 4: [Traverse points of Station P.]
1, which is measured last, is [End point]
Example:
For point 1
“Closing errors/Total length is the horizontal distance error at point 1 between measured
value and theoretical value.
“Total length” is the distance measured in the order of 1-2-3-4-1
For point 3
“Length between last station P. & current P.” is the distance between 2 and 3
“Length between start P. & current P.” is the distance measured in the order of 1-2-3
OPEN TRAVERSE
Set the instrument in the order of 1 and 2,
then make the measurement.
1: [Start point]
2: [Traverse point of Station P.]
3 and 4: [Traverse points of not Station P.]
Example
：
For point 4
“Length between last station P. & current P.” is the distance between 2 and 4.
