| Summary: | Topographic measurements of mining areas using the Terrestrial Laser Scanner (TLS)
tool have several weaknesses, namely, there are safety issues because they have to set
up tools directly in the area of observation object and it also takes a long time. With
the development of Unmanned Aerial Vehicle (UAV) photogrammetry technology, it
is hoped that it will become an alternative to topographic measurements in the mine
area, which can cover the weakness of TLS. This final project aims to obtain the results
of the accuracy of UAV photogrammetry measurements and evaluate the results of the
implementation of topographic measurements of the mining area using the UAV
photogrammetry method as a material for making work instructions for measuring the
topography of the mine area using UAV photogrammetry. The study was conducted
at the PT Berau coal mine lokasi in a disposal area of approximately 30 hectares. Data
acquisition begins with the measurement of the Ground Control Point or abbreviated
as GCP, followed by the acquisition of UAV and TLS photogrammetric measurements
at the same time, the UAV photogrammetric data processing is carried out with various
GCP and TLS configuration schemes into a Digital Terrain Model (DTM), then the
analysis is carried out, by assuming the TLS DTM as true data. Based on the results of
the analysis, the vertical accuracy of UAV photogrammetry with various GCP
configurations, including the configuration of 4 GCPs which are only at the boundary
of the research area, is still within the tolerance of the 1:1000 scale map, which is
below 10 cm. Then for the difference in volume percent formed between DTM from
photogrammetry and TLS, which is 0.13%, this is still within the tolerance of
American Society for Testing and Materials (ASTM), which is 2%. It is hoped that the
resulting work instructions, based on the results of the evaluation of this study, can be
applied to topographic measurements of mining areas using UAV photogrammetry. |
