ANNEX

PROCEDURES FOR THE .SURVEY AND DEMARCATION
OF TEE BOUNDARY BETWEEN THE REPUELIC, OF INDONESIA
AND . PA.PUA . NEW GUINEA

SC.OPE _OF OP_ERATIONS

1.

Survey and demarcation of the boundary will be
conducted concurrently by survey teams of Indonesia
and Papua New Guinea.

2.

The scope of operations will consist of the following
activities:
(a)

Study of all aerial photographs, satellite
imagery and maps to determine the probable
location of the boundary.

If necessary, new

aerial photographs will be taken.
(b)

Investigation of the existing boundary monuments
and auxiliary astro stations (BAS and TA) as
determined by the Joint Indonesia Australia
Border Survey in 1966 and 1967.

(c)

Establishment of new boundary monuments to
replace existing boundary monuments if they are
missing or in danger of being lost.

The new

boundary monuments will be placed on the
meridian through the old positions and not more
than 1 kilometer distant from the positions •

• • • /2

- 2 -

(d)

Establishment of new boundary monuments at
specified sites on the geodesic line between the
existing boundary monuments or their
replacements by Doppler satellite observations
at the auxiliary stations and traversing from
these stations. The proposed general location
of these is indicated in Appendix D.

MONUMENTATION

1.

2.

There are two types of monuments to be used, namely:
(a)

Type A as per Appendix A, will be used for
auxiliary stations close to the correct position
of new boundary monuments to be established.

(b)

Type B as per Appendix B, will be used for new
boundary monuments or the replacement of
existing monuments.

Suitable permanent recovery marks will be planted
within 200 metres of every type A or type B monument.

DATUM

Consistent with the existing boundary monuments, the
final co-ordinates of the new boundary monuments will
be on both astronomic datum (geoid) and WGS-72 •

. . • /3

- 4 -

(ii)

Papua New Guinea will translocate to
existing border monuments.

(iii)

Papua New Guinea will locate intermediate
auxiliary stations by translocation.

(iv)

Indonesia to locate existing stations and
auxiliary stations by point position
techniques with 40 passes.

(v)

If the co-ordinates of the auxiliary
stations as determined by Papua New Guinea
by translocation do not differ from those
determined by Indonesia by point
positioning by more than 10 metres, the
Papua New Guinea co-ordinates will be
adopted.

(vi)

The border point may then be laid in so as
to lay on the geodesic joining the two
adjacent existing markers.

(vii)

Indonesia will then subsequently calculate
transformation parameters to the local
geoid determined by relation to the old
astronomical co-ordinates and the WGS - 72
co-ordinates. Indonesia will then
calculate the position of the new border
point in the terms of the local geoid.

(viii)

If the longitudes as determined by either
side are within 2 seconds of arc of the
positions as determined by the other they
will be accepted.

...I5

(ix)

(d)

If they are not within 2 seconds of arc,
the Joint Technical (Sub) Committee will
reconvene to consider the differences.

Spot photography.
Each monument will be photographed from
altitudes of 1000 ft and 3000 ft respectively.
In case those monuments are established in
featureless environment, additional photography
has to be taken from a higher altitude, not less
than 7000 ft.

(e)

Description of monuments.
The elements of station description of each
monument are;
Monument number and name of place
Preliminary and final co-ordinates
Description of access to station and
topographic sketch of its location and
environment
Recovery marks and diagram
Photographic views from North, East, West
and South.

2.

Standards of accuracy.
(a)

Doppler satellite observations.
With the view of simultaneously obtaining the
necessary accuracies for Project I and II
respectively, 40 acceptable passes are required
at each station.
This will give an expected absolute ac curacy of
10 metres.

• •• /6

- 6 -

(b)

Traverse.
Position closure after azimuth adjustment will
be in the order of 1
5, 000.

(c)

Local azimuth will be determined astronomically
or by gyro observation to the nearest 20 seconds
of arc.
