6.3 DENSIFYING CONTROLS ALONG THE CENTER OF THE
'I'he detailing of the right of way of Enugu - Abakiliki road was
done by establishing points along the centre of the road. This is as a
rcsult of the specification for the federal high ways 300m interval of
controls along the centre of the road and along the sides 45m from the
centre of the road. b
'This was achieved using total station on 10 minutes static mode
and this was completed in one week. The base was set up on a primary
control and we would move the rover on the vehicle and the handheld
was set on 200m navigation mode. As the vehicle move, the distance
would reduce until it reads zero, then we would stop to set the rover on
the point to stay for 10 minutes and continued until the termination or
rather the limit of the job. The dimensions of the beacons were 40X
40X 1 Zcm width.
6.4 SETTING OUT OF RIGHT OF WAY AT BOTH SIDES OF
THE ROAD
This was done on Auto CAD land development sohare which
placed the points at both sides of the road at 45m from the centre of the
road. Downloads were done daily often a day work to free the
flash
(Downloads of data)
card of the GPS for the next day job. The job lasted for two weeks and it
was a huge success.
6.5 CONCLUSION
The right of way demarcation was successfblly carried out
according to the specification given by the office of the surveyor-
General of the federation.

'I'hc client was able to show us the land. Reconnaissance was hter
carried out on a fresh day where we ascertained the control to link our
survey to.
7.6.1 SURVEY PROPER
The instrument promark 111 GPS with its reflectors were mounted
o n the existing Government beacon around the area. The control Was
transferred to the area in question. All the point indicated during the
reconnaissance was occupied using the stop and go method. This was a
bit cii fficult initially because of the poor satellite resection.
7.6.2 DATA PROCESSING
The survey data was downloaded from the flash card of the GPS
and we used GNSS global navigation satellite system software for the
post processing. The adjustment was done by hammering of the points
and the plotting was finally done in AUTOCAD 2004.
(Waiting for the satellite tracking) 1
7.63 PRESENTATION
The plan was made available to the client both in soft and in hard

7.6.4 CONCLUSION
Even though we initially faced difficulty as a result of poor
satellite resection it was successfully carried out and quite an experience
for me.

8.4.1 PLANNING OPERATION
The planning for global positioning system is similar to
triangulation. A map of part of Nigeria was used for the planning.@A
wcll conditioned triangle was used for the baseline, the maximum of the
baseline must be determined. This is to minimize error in length for
hetter accuracy.
The time of the observation must also be put into consideration.
This can bc achieved with all" satellite availability" chart Almanac
installed on "leica GSP" ofice software. To access this Almanac, is
similar to star almanac, check satellite availability in leica GPS ofice
software by entering the data of observation. The available satellites
with respect to time of that day are displayed with the respective GDOP
(Geometric division of precision).
In the field: we navigated
to the point to be occupied using the handheld GPS since we couldn't
trace our own point. However, the reference was mounted on the L40
minna datum few hours before our team took off with our rovers to
respective stations to occupy. we were able to find the positions with the
hand held CiPS. Since the EIDC( expected position errors) was about 3m
radius on getting to the point the GPS beeped and that is a sign that .we
are within the point.
Ilowever, it was a static observation, the instrument was set up on
the station, and the tribra was mounted on the tripod, and properly
leveled on the station point
Consequently, since it is a differential GPS observation, we
started from the origin CL40( Minna datum) and coordinated other
points and extended the control to other points.
8.4.2 I)(I CC'NI, 0,I /IS 0 1.' /),4 TA PROCEDURE
1 .Insert the Dungle drive" into the system
2. lnsert the flash card into the compact flash "PCWCard (F-drive)
3. Double click leica GPS office software and go to click file and screw
to new to create
4. inputhet all necessary parameters click. "imput" and select raw data
5. Click "GPS" to view
Assign data by clicking "Assign" (Back up dialog box appears)
Click "yes" to batch up data (the point is automatically plotted)
Remove for all other flash cards.
I . Click view/Edit to bring out the plotted points.
2. Right click the poitit of interest say ABI which is to be used as the
control
3 . Select properties to view the properties of AB.
4. Select control in place of navigation as the status of ABI and input
the known coordinates
5. Click GPS processing
8.4.4 AD-JUSTMENT OF COORDINATES
Prior to adjustment process, first select all the points selected by
hammering i.e. click GPS process and select all observations bars by
clicking them.
The conversion of coordinates from WS 84 to Clarke 1880 was
done using geographic calculator "Gedal'
8.4.5 PROBLEMS ENCOUNTERED
Communication where these is no network coverage, rainfall,
flocks of cow passing by and the long distance traveling to occupy a
station.
8.4.6 CONCLUSION
The control extension w ecuted uccessfblly ex
gotten was acceptable within the range required.

9.4 METHODOLOGY
9.4.1 ACQUISITION OF SATELLITE IMAGERY OF ABUJA
'The Quick bird satellite Imagery of Abuja was bought and was
prepared for the project. In the GlS lab in the office, image processing
was (image refinement enhancement etc) carried out using I L W
software. Then the image was exported to AUTOCAD 2000 where it
was properly gm-referenced with some coordinates of conspicuous
feature in the imagery which we did confirm with the hand held GPS.
These points were located and coordinated on the p u n d with the GPS.
9.4.2 VECTORISATION
All the feature in the imagery were vectorized using the AutoDesk
CAD overlay for automatic vectorization the vectorization took 6 days
to be completed.
9.4.3 IMPORTING FROM AUTOCAD TO ARC VIEW.
The digitized street guide of Abuja from the satellite imagery was
imported to Arc-view for population of data base. Some of the popular
places and roads were filled in and we (field men) were sent to the field
to get the street names and some important structures on the course of
getting the street names with the printed map of Abuja phase 1.
For each day we went to the field we come back to the office to
f i l l in the information on the system. This lasted for weeks and finally
we were able to cover the phase 1 of Abuja master plan.
9.4.4 POPULATION OF DATA BASE
All these data of streets, building names, roads etc were filled into
the AutoCAD and finally imported to arc-view for population. Different
layers were created for different features for proper quarry.
9.4.5 IMPORTANCE OF PROJECT b
It was realized that with such tool, one can achieve lots of things
with it. Among which are: - navigate phase 1 of Abuja master plan at a
glance. This street guide will be useful to:
Individuals and different cooperate bodies like Nigeria police, federal
road safety commission, fire services, to aid location of place and
shortest distance when the need arises in crime control, disaster
management, road network.
9.4.6 CONCLUSION
The project was successfully carried out and it was a niece
experience for me.

10.0 TRAININGIWORKSHOP ATTENDED
the use During the industrial training (IT) a training workshops on t
of GPS SR20, Leica DNA10 digital level and promark 111 GPS
organized by the Office of the Surveyor-General of the Federation
which included all the Chief residence surveyors fiom each of the Geo-
political zones were attended . I was availed the opportunity of
b participating in the training workshop.

The training lasted for a week with a practical to demonstrate the
accuracy and our understanding of the principles of the instruments.
The training further exposed me practically on the use of GPS, in
carrying out survey jobs.
(Taking reading )
Downloads of the perimeter survey done to test the participants
understanding were downloaded and plotted using AutoCAD
The SR20 GPS and Promark I11 GSP receivers allow the user the
maximum flexibility, the GPS receiver can be used as a high accuracy
land surveying device, a powehl GIs data collector and reference
station also.

A workshop organized by the anti-corruption and transparency unit of
the Office of the Surveyor-General of the Federation on the theme
"transparency and cost of corruption" was attended.
10.1 CONFERENCES ATTENDED
I had the opportunity of attending conferences during my
industrial training.
The Annual General Meeting and conference (AGM) of surveyors
in Nigeria, held at Jos in crest Hotels, plateau state from 2"d-6th July,
2007 was attended. The different paper presentations extracted from
virtually every area in surveying at the AGM exposed me to the reality
in surveying. Theme is "Rural and Urban development in kigeria,
issues, problems and
v - . -
Options"
(marketing survey instruments at the AGM)
The conference on survey coordination and advisory board on
survey training conference held at the international conference centre
area 11 Garki, Abuja from 1 0 ~ - 13 '~ September 2007, was
attended. The theme of the conference is "the role of surveying and
mapping in conflict management in Nigeria" the conference X-rays the
importance of surveying and mapping in conflict management.

Conference
held at Rock view hotels Abuja was attended. This was organized by the
mapping division of OSGOF. During the conference I was able to know
about Global navigation satellite system (GNSS) GNSS is simply a
satellite communication technology that attends to the requirements of
Global navigation services, it is the standard generic term for satellite
navigation systems that provides a set of positioning, navigation and
timing services with global coverage.
10.2 PRODUCTS OF AFREF
Very accurate GNSS satellite ephemeredes and related
information. Positions and velocities of tracking stations satellite and
receiver clock information ionispheric and tropopheric information.

CHAPTER ELEVEN
I I .O PROBLEMS ENCOUNTERED
The duration of the training was also marked by certain challenges,
though not enough to affect the smooth working condition during the
period. a friendly working environment was evident all through the
period of the industrial training . I gained GIs, surveying and mapping
knowledge respectively. therefore, 1 am ever grateful to SIWES for the I
opportunity 1 was offered that impacted and exposed me to my field of
study.
flowever. I experienced financial difficulty during the period of
my training; the cost of transportation was so high that the little I had
was not enough. that subjected me to work some distance on foot to get
to the office. I did not encounter serious problems
Also. searching for a place of attachment was a bit difficult,
checking the proximity of where one resides, It was quite a burden
moving from one place to another in search of place of attachment.
11.1 RELEVANCE OF THE SIWES PROGRAMME
The SlWES programme is a "must do" for all profession to expose and
further enlightened the student in one's area of specialization. I had the
privilege of working with modern surveying instruments like Leica
GPS, DNA10 digital level, Total Stations, Promark 3 GPS, etc in
carrying out surveying jobs. 42
I carried out the GIs processes severally. It was then that the
importance of digitizing maps became so real than it had ever been. I
also interacted with those at the helm of affairs when it codes to
surveying and mapping in the various Conferences/Workshops I
attended, that further boost my interest in Surveying as a profession.
I gained practical experience of AutoCAD, Arc View, Swfer 8,
Micro Station, GNSS, Google Earth Software and others. 1 had the
privilege of working with various States Administrative Maps. I dorked
with Delta, Bayelsa, Rivers, Katsina, FCT Administrative Maps.
With my present level of exposure, 1 now appreciate the value of
Surveying and Mapping in the development of the nation, especially in
the application of GIs in solving problems also the conversion of
analogue map to digital maps, for up date for the ever changing
environment of our country.
This experience is really going to have positive impact on my
career, and I thank SIWES once more and especially the Office of the
Surveyor-General of the Federation for the opportunity given to me to
get this high esteem of knowledge.
The SI WES period exposed me to civil service environment. It gave me the opportunity of having a fecl of the civil service environment, which is quite different from the academic setting. The entire experiences gave me an insight to what one will be exposed to after graduation. The SIWES period was quite interesting.
CHAPTER TWELVE r"
12.0 GENERAL, APPRAISAL OF THE PROGRAMME.
The SIWES programme could be improved on through the
following ways;
. 12.1 PROVISlON OF PLACE OF ATTACHMENT
There i s need for S I W S managerslorganizers to provide online
@ information concerning place of attachment that includes:
1. Names of establishment (that offer placement relating to one's
discipline)
2. The addresses of the establishments
3. The relevance of the establishment to different courses of study.
I discovered the need for such information to be in the SIWES website if
there is one and if there is none, they should get one to enable student!?
to access such on the internet. One of the ITF function is to provide
information on companies for attachment and assist in the industrial
placement of students.
12.2 REGULAR SUPERVISION OF STUDENTS.
It is the duty of the ITF to provide supervisions for students.
Unfortunately, all through my stay in the oEce of the Surveyor-General
of the Federation, no supervisor came. Regular supervision will enhance
the programme 44
for this will bring the consciousness to students and make them to be
punctual and participate actively in any task being undertaken by the
S establishments.
12.3 MONTHLY DISBURSEMENT OF ALLOWANCE.
Currently, the allowance payable to students by the Industrial
Training Fund (ITF) only gets to them at the end of the programme. It is
necessary to bring to the lime light the difficulties students go through
during the training period. Students' places of attachments are far fiom
home, they end up staying with relations, fiiends or get their
accommodation which is very demanding. In this case, students face
financial difficulties especially when the organization does not have any
financial provision for students on industrial training. With monthly
disbursement, students stand better chance of enjoying the programme
12.4 ADVICE FOR FUTURE PARTICIPANTS
Many students prior to their attachments consider monetary
commitments in establishment than the experience which is the aim of
SIWES, I therefore, advice future participants to put the experience fmt
for it is worth more than the money, money can come latter.
'This is the only opportunity to relate the theoretical knowledge in
the lecture rooms to practical work as experienced in the society and this '
must be taken seriously as this build and prepare one for a promising
Future
12.5 ADVICE FOR SIWES MANAGERS 1
To facilitate the full realization of the objectives of SIWES, it is
essential to ensure the proper training of students in preparing them for
world of work. One of the important instruments of maintaining this
programme is to get a website so that information can be accessed freely
concerning SIWES, Also, to ensure regular visit by the supervisor to
b places of attachment.
