Available methods of survey
The
boundaries will usually be surveyed by closed theodolite traverse.
Other methods include staring the traverse on checked and proven
boundary beacons and ending same on checked and proven boundary beacons
insofar as the starting and closing beacons form part of the new
boundary of the property surveyed .For any of the methods, the position
closure (after Azimuth adjustment where applicable)shall be 1/5,000.
Field books
All field observation must be entered in the field book clearly with neat booking.
Clear
diagrams: Diagrams of plot survey must be unambiguously represented in
the field book. Such diagram will also show permanent features within
and along area adjacent to the plot.
Electronic field book may also be used.
Computations:
Computation – manual or electronic shall include the following:
Azimuth computation where necessary.
Reduction of bearing showing angular closures.
Distance, measured/corrected.
Un-adjusted/final coordinate/linear closures.
Area computation.
The required computational accuracy are as follows:
Deduced bearing to the nearest 10â€
Corrections to measured distance for slope, standard(standardization where applicable) to the nearest mm.
Coordinates to the nearest mm.
Area
Allowable drawing scales:
The following drawing scale shall be used for plotting:
1:250
1:500
1:1,000
1:2,000
1:2,500
1:5,000
1:10,000
1:20,000
1:25,000
Different
scales may be used for the main survey and the connection where the
latter is long. Any chosen scale should permit the clear representation
of all measured detail, bearing, distances and area on plan.
Electronic copy maps must be prepared using base data with relevant location accuracy.
STUDY AREA
The
study area is medium density layout, Ikot Offiong, Ifuho, Ikot Ekpene
Local Government Area, Akwa Ibom State and it is located on latitude 58
46 longitude 135 00 UTM zone 32 north. The estate is situated along Ikot
Offiong road on the south and on the west 500m away from Aba
