INTRODUCTIONIn surveying compass, observations and measurements on line survey
bearings and distances involved. Surveying compass bearings inthe mean angle
made by the line depth with a particular reference meridian.Read the compass bearing and distance are measured with a band depth or
tape measure. Survey lines did not form a triangle frameworks
as measuring chain. Continuous series of survey lines will
form a circuit known as the traverse. The direction of the line depth
is based on a reference meridian or north magnetic
magnet. The points at which the compass bearing is fitted to the observed
referred to as a depth stop.
To build a compass traverse, bearing and distance to the line depthobserved to enable the direction and length of the line depth
dipelot. Base line and the review is not needed in
measured as the formation of chain traverse

Method and compass observeObservations of a compass bearing to the target is
based on the following measures: -
a. Install and go get a compass on the stop tripod
selected. Level the compass so that the compass dial are in
free conditions.
b. Point the blade calm to the target (pole row) and aligned
cool bar with a target capillary.
c. Read the bearing through the prism of reading on the superposition of capillary
reading a compass dial.
d. If the compass dial are not located in a quiet(stop / rest) press the stop pins carefully to
accelerate it stops.
e. If the reading on the compass dial blur, adjust the prism of
down the rise of the prism.

CONCLUSIONTherefore traverse compass can be reflected clearly on a map or plan when
distance and direction of survey lines and the position of a point to know.
Traverse an order of survey lines, respectively.Bearing and distance will be determined with the right tools. in
traverse a compass, read a line bearing compass and the distance y
depth measured with a chain or tape measure. There are two types of traverse
compass, namely: -
i. Closed traverse
ii. Open traverse
