Suitability of UAV photogrammetry as a platform in topographic mapping / Siti Nurshahirah Othman

Othman, Siti Nurshahirah (2019) Suitability of UAV photogrammetry as a platform in topographic mapping / Siti Nurshahirah Othman. Degree thesis, Universiti Teknologi Mara Perlis.


There are several instrument and method used to collect the details of topography
such as Total Station, Unmanned Aerial Vehicle (UAV) Photogrammetry, Real Time
Kinematic Global Positioning System (RTK-GPS) and Terrestrial Laser Scanner.
Among those instrument and method, most frequent used was Total Station because
of its can give high accuracy output. However, since few years ago UAV
Photogrammetry become an alternative way to collect the topographic data because it
is lower in operating and manufacturer costs, reduce time and reduce man power. The
aim of this study is to analyze the potential of UAV Photogrammetry as a platform to
collect the topographic data. In this study. Aero M fixed wing UAV and Topcon ES
Total Station was used to collect the topographic details of Academic Height, UiTM
Arau, Perlis. Ground Control Points (GCPs) were established by using fast static
method of GPS observation while, the Check Points (CPs) was established by using
Tacheometry method (Total Station). An analysis carried out from this study is
qualitative and quantitative assessment. The qualitative assessment was done by
comparing the visualization of DEM and contour lines generated. Based on the result
of qualitative assessment, the DEM and contour line generated from UAV was more
beautiful and smooth. The quantitative assessment was verified by compared the
number of features collected from the survey and digitized and calculating the
planimetric and elevation Root Mean Square Error (RMSE) of coordinates from UAV
Photogrammetry and Total Station. Based on the assessment, the result shown that the
number of features collected from UAV was greater than Total Station, while the
result of RMSEx is ±0.2244m, RMSEy is ±0.1996m and RMSEz is ±0.530m. In
conclusion, this study shows that UAV Photogrammetry data can be used for detailed
topographic survey.
