3.4 TOTAL STATION TACHEOMETRY

3.4.1 COMMENTS AND PROLEM ACED

On our next project, our task is to do the detail survey by using total

station in our station. As usual, our group arrived at UKK Lab around

7.4a!."hen #e start borro# the instru!ent and the #eather $or that day

is %uite good $or us to do the &eld #ork. A$ter borro#ed the instru!ent, #e

started to go to our project site #here usually sa!e site #ith a project

one. 'hen arrived at project site, #e direct go to a station one to set up

the instru!ent. At station one #e are setup a total station, and at a

station &ve #e set up a pris! to get a back sight bearing.

(n this project #e !ust use t#o !ethods #hich are )*+ detail

surveys and total station detail survey. Our group has used a total station

!ethod at a station one. (n order to do this, the total station !ust be

con&gure be$ore it can be used #hich are enter the coordinate o$ thestation, enter the height o$ the total station, enter the height o$ pris! pole

and enter the reduced level o$ the station. e$ore #e start observed, #e

!ust take height o$ total station and height o$ pris!. A$ter that, #e

observed each point and each spot height #here is established. )ach

point #e !ust observed a northing, easting and reduced level.

*uring doing this project has so!e another group asked our

!e!ber o$ group to do this project but another !e!ber o$ group stilled

doing a project. 'hile observed at station one, #eather is very hot.

Around ten o-clock #e are &nished observed at station one, and #e are

rested in ten !inutes. "hen #e continue our detail survey at station t#o,

#e still used a sa!e !ethod $or doing a detail survey at this station. (n

this station #e only $ace a proble! #ith o$ our station #here the

location is %uite bushes and there are a lot o$ aides !os%uito and !any

insect surrounding the station, all our group !e!bers has been bitten#ith a lot o$ aides !os%uito and #e take this proble! as a challenge $or

us.

"hen #e continue the detail survey, the procedure still sa!e #ith at

the station one. +ake sure be$ore begin an observed #e need to take

height o$ total station and pris!. Our group has taken a northing, easting

and reduced level still #e &nished observed each point. /or the next

station #e !ust continue another !ethod #hich is by using )*+ detail

From the diagram, the height of the observed point can be computed as follows:

Sin = V/D

V = D sin

H = D kos

H = hi + V hp

Reduced level at Prism = Reduced Level Station + H

Page4;

hi = height o !D"

hp = height o prism

D = slope distance

= vertical angle
