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.

To carry out survey work using eTSM, the work flow are as follow:
Before we start the survey work, the Nomad Data Logger must first establish connection with
the total station.
1. Create a new job first, after that, in the job menu, select Workspace. Choose the correct
COM port (in this fieldwork, COM port 3 is used).
2. Click on the Setting button and select the correct Instrument and model. E.g. Topcon
– ES-Series. Make sure the settings (Baudrate, Databits, Parity & Stopbit) are match
with Total Station as well. Then click Set button.

3. After the instrument setting is done, click the Save button. Once the instrument setting
is saved, back to the main menu, select the option Test Connection. Then click on Test
button after setting done, if connected, the Instrument will be showing 0.0000 for
Horizontal Bearing and “Connected” will be shown.
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.

1. Instrument at station A, measure distance A-B. Click the measure button.
2. Instrument at station C, measure distance C-A. Click the measure button.
3. Instrument at station C, measure distance C-B. Click the measure button.
Once the DFT is completed, we will start our survey work. A good datum line is selected. All
survey work must start from the datum for starting traverse line. Under the Survey menu, go
to Datum.

1. Key in the initial start bearing, your “Sit Station ID, “To Station ID” and select or
manually key in your marker type.
Note: If the is any stone number for a particular station ID, you may enter in the
particular stone number directly the field under the marker type
2. If you are start from CRM points, the Datum Dari, chose for RO.
3. After all the information is keyed in, tab the Measure button to measure the bearing
and the distance for your face left. The measurement value will be retrieved
automatically.
4. Then continue measure the bearing and the distance for your face right.
Note: For step 3 and step 4, once you tab the measure button the screen below will
appear indicating that measurement is in progress. If the screen below does not appear,
you need to tab the measure button again to start your measurement.
5. After all the measurement required was measured, tab on the reduce button to
reduce the measurement to produce mean, reduction and final value.
6. Finally tab the save button to save your datum record. You can view your field book by
tabing the button
Note: The measurement that you have measured will only be save once you tab the save button.
If not the measured bearing and distance of that particular record will not be saved
Once the datum is defined, the traverse can be continued. Go to the Survey menu, go to
Traverse.
1. Select the “1.Sit Stn”, the “2.Back Stn” from the provided combo box and the type in
the “3.To Stn”. Then select or manually key in your “4.Marker type”
2. Sight to the [Back station] and tab at the [P.Kiri button ] to set the back bearing for
your [5.P.Kiri].

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.

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

5.0 Result
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.
