Abstract:

The importance of points location on the earth surface with the use of digital instruments cannot be overemphasised this is because the accurate location of points depends on the quality of the instrument used. Different equipment can perform the same function. For example, total station can be used to coordinates points on the earth surface, likewise the DGPS can still be used for the same purpose, but the accuracy of each result will be different from each other. Hence, the research. This research, aims at comparing data collected from Total Station to that of DGPS on some already established survey points within the study area. The instruments compared were Leica Total Station (TC 805 model) and Hi –Target V30 GPS. The methods used in achieving the desire goal include: reconnaissance survey, test of instrument, data acquisition by running traverse on some control points. Moreso, data collected were processed and analysed. The linear accuracy in Hi–Target V30 GPS and Leica Total Station (TC 805 model) was 1/600,000 and 1/300,000 respectively. Furthermore, statistical analysis was carried out on the results collected. From the analysis, it was concluded that the result from Hi–Target V30 GPS is more accurate compare to Leica Total Station (TC 805 model).
