Define traverse.......................................
is continues line with bearing and distance
is that type of survey in which a number of connected survey lines form the framework only
is continues line with bearing only
is continues line with distance only
Define Opened Traverse..................................
When the lines form a circuit ends elsewhere except starting point
Start and close the traverse at same point
Start and close the traverse at known coordinate
Define Closed Traverse_________________________________
Close the traverse at unknown coordinate
When the lines form a circuit ends elsewhere except starting point
Start and close the traverse at same point
Define Latitude ______________________________
line is its projection on the north-south meridian and is equal to the length of the line times the cosine of its bearing.
sum of all latitudes must equal zero or the difference in latitude between the initial and final control points
line is its projection on the east-west meridian and is equal to the length of the line times the sine of its bearing.
Define Departure _________________________________________
a line is its projection on the north-south meridian and is equal to the length of the line times the cosine of its bearing.
A line is its projection on the east-west meridian and is equal to the length of the line times the sine of its bearing.
the sums of latitudes and departures do not equal zero, corrections must be made.
