1.0 Introduction

Cadastral surveying is the discipline of land surveying that relates to the laws of land

ownership and the definition of property boundaries. It involves interpreting and advising on

boundary locations, on the status of land ownership and on the rights, restrictions and interests

in property, as well as the recording of such information for use on plans, maps, etc. It also

involves the physical delineation of property boundaries and determination of dimensions,

areas and certain rights associated with properties, whether they are on land, water or defined

by natural or artificial features.

Cadastral surveys are generally performed to subdivide land into parcels for ownership

under a land title and to re-establish boundaries of previously surveyed properties to determine

the physical extent of ownership or to facilitate the transfer of the property title.

The scale of cadastral maps is of great importance. Since the object of the map is to

provide a precise description and identification of the land, the scale must be large enough for

every separate plot of land which may be the subject of separate possession (conveniently

called a “survey plot” or “land parcel”) to appear as a recognizable unit on the map. When map

data are stored in a computer, they may be drawn at almost any scale and this can give an

impression of greater accuracy than the quality of the survey data may warrant.

Cadastral survey work done by using traditional method that is using a total station and

solar observation. The Datum use to start the work is the datum that required according to the

survey regulation given. Pipe is used to plant 2 boundary marks at suitable location (if Datum

is peg). Other boundary marks to be planted with peg only.

Boundary lines cannot be use as the traverse line except for boundary line that to be as

Datum. The coordinates use for solar observation is the coordinate provided from the Certified

Plan given. Field work booking, and its regulation must be done during the survey work and

should apply the ‘C’ corrections and misclosure. ‘M’ correction is applied after traverse is close

and ‘C’ corrections.

Then, calculation sheet (jilid kira) must be done for Bowditch adjustment and area

calculation. Refixation is done on missing pegs with in the Certified Plan. When do the survey,

all surveyors must follow the regulations by UTM, such as do not enter restricted area while

doing the survey work. Lastly, final product is to produce Certified Plan as JUPEM guidelines.

After the Nomad Data logger is paired and connected to the Total Station, we can start

to carry out the survey work. Make sure the correct job file is selected before proceed with the

survey work. The first thing to do when we start a new survey work is to perform Differential

Field Test (DFT). Under the Survey menu, select Diff Field Test.

4.3 eTSM Operation Solar Observation, C correction and M correction

eTSM can be used to perform solar observation to provide M correction.

The eTSM module can also automatically perform correction for the traverse.

Everything is automatically calculated in the eTSM module. We used the C correction module

to carry out closure correction for our traverse.


17

We also perform meridian correction by using the M correction module in the eTSM.

6.0 Discussion and Recommendation

Differential Field Test shall be conducted whenever starting a new job. For work that

began with two (2) Cadastral Reference Mark mutually visible, Differential Field Test shall be

made on the line connecting the two Cadastral Reference Mark. If there is a difference in

distance between direct observations using Total Station compared the calculations results of

two (2) Cadastral Reference Mark, distance calculation results of two Mark Cadastral

Reference should be adopted. Difference must not exceed 0.020 meters. For difference exceeds

the limit 0.020 meters, the following actions should be taken if:

a) Differential Field Test in the 0.010-meter limit, redo the determination of Cadastral

Reference Mark.

b) Differential Field Test is not within limits, calibration must be made onto total station

instrument.

Distance AB = 65.774m

Distance CA = 37.403m

Distance CB = 28.371m

7.0 Conclusion

In conclusion, there are many reasons why Differential Field Test should be done in

order to get the best accuracy in the survey observation. We need to know if there is any error

in the instruments that might give a huge impact towards the product of survey in the end. The

test also can make the students to able handle the equipment in the right way without any

problem.
