3.2 DATA ACQUISITION
Field observations involved the acquisition of data in accordance with the specification given. The data acquired during the field measurements were distances and angles relative to the horizontal and vertical planes that is, to determine X, Y and Z coordinates of points. These are the procedures undertaken on the field.
(i) Test of instruments.
(ii) Theodolite traverse.
(iii) Spirit leveling.
(iv) The choice of scale.
(v) Detailing by the use of total station(ray method).
(vi) Curve designation and setting out.
3.2.1 EQUIPMENT USED
The following were the equipment used in the execution of the project.
i. One digital theodolite (GEOMAX - 910586) and its tripod
ii. One automatic level instrument and its tripod
iii. Two leveling staves
iv. One steel tape(100m)
v. Two foot plates
vi. One plumb bobs
vii. Field books (Both traverse and leveling field books)
viii. One cutlass
ix. One Leica (TC600-407611) total station and its tripod
x. One reflector
xi. Writing materials
xii. Red flag
xiii. Bottle cork and nails
xiv. Microsoft word (2010)
xv. AutoCAD software.
3.2.2TEST OF INSTRUMENT
This was done in order to ascertain the working condition of the instrument collected from the store department, the collimation errors were checked to know if any exist.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTTheproject was focused on the execution of route surveying for the purpose of road reconstruction from Oriawo along Ogbomosho road, Oyo to School of Science, Sabo Oyo Town. Stations were selected along the existing route at regular intervals as in the specificationsTheodolite traverse was run over stations, while levels were observed along the longitudinal and cross-sections of the traverse lines. All data were gathered with effective orientation from the controls, these were used to pro ... Continue reading---

CHAPTER TWO - [ Total Page(s): 3 ]Traverse is a sequence of connected straight lines whose direction and distances have been measured. Traverse is also the process of connecting series of lines with known bearings and distances. It is subdivided into first order for precise measurement and second order for the establishment of secondary controls while the third order is meant for survey of tertiary and topographical features.Basak (2000) explained leveling as the art of determining the relative vertical heights of different poin ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 SUMMARY, RECOMMENDATION AND CONCLUSION5.1 SUMMARYThe reconnaissance, which was the main planning, was carefully carried out because of its importance to good execution of any survey project or work. Having carried out the reconnaissance, six (6) second order control stations were located and used as connection along the given route. The total number of nineteen (19) stations excluding the controls where the angles and distances were determine by a closed traverse met ... Continue reading---
