Abstract
Penelitian ini mengenai Studi Ketelitian Planimetrik pada
permukaan (3D) model dalam survei tiga dimensi menggunakan
terrestrial laser scanning (TLS). Jembatan Suramadu yang berlokasi di
antara Kota Surabaya dan Kabupaten Bangkalan sebagai penghubung
Pulau Jawa dengan Pulau Madura ini terpilih sebagai objek penelitian.
Instrumen teknologi laser yang digunakan sebagai pembanding adalah
Geomax Zoom 300 (Terrestrial Laser Scanner) dan Ruide RTS-822 R3
(Electronic Total Station) serta GPS Geodetik Topcon-Hiper Pro untuk
pengukuran titik referensi (BM) dan sebagai pedoman titik koordinat
georeferensi. Dua puluh titik ada pada posisi yang sama di masingmasing
model permukaan pengukuran yang dipilih. Koordinat hasil
pengukuran Electronic Total Station dan Terrestrial Laser Scanner
kemudian diubah menjadi koordinat global (UTM) menggunakan proses
georeferensi hasil pengukuran GPS Geodetik. Koordinat 3D dan
ketinggian Jembatan Suramadu dihitung untuk setiap model. Perbedaan
jarak koordinat dan ketinggian dianggap sebagai kesalahan dalam x, y,
dan z. Standar deviasi perbedaan jarak koordinat 3D adalah x =
0.240119501 m, y = 0.299053305 m, and z = 0.172432871 m.. Dengan
interval kepercayaan 90% pada uji statistik, beberapa perbedaan jarak
tidak jatuh dalam kisaran toleransi (sekitar 10 %).. 3D visualisasi
ketinggian Jembatan Suramadu yang dihasilkan dari data Terrestrial
Laser Scanner lebih tepat daripada yang dibuat dari data Total Station.
Di masa depan, 3D seperti visualisasi model permukaan dapat
digunakan untuk dokumentasi, pelestarian dan rekonstruksi bangunan
jembatan.========== Research subjects reported was the study on model of threedimensional
(3D) surface model of Suramadu Bridge in threedimensional
using terrestrial laser scanning (TLS). Longest bridge
located between Surabaya and Bangkalan as connecting Java and
Madura was chosen as the research object. Laser technology
instruments used for comparison is GeoMax Zoom 300 (Terrestrial
Laser Scanner) and Gowin TKS-202 (Electronic Total Station) as well as
geodetic GPS coordinates for the reference measurement and the longest
bridge georeferenced. Ten points there are in the same position in each
of the measurement surface model chosen. Coordinate measurement
results Electronic Total Station and Terrestrial Laser Scanner is then
converted into a global coordinates (UTM) using georeferencing process
Geodetic GPS measurement results. 3D coordinates and altitude longest
bridge is calculated for each model. Coordinate distance and altitude
difference is regarded as an error in the x, y, and z. The standard
deviation of the differences within the 3D coordinates are x =
0.240119501 m, y = 0.299053305 m, and z = 0.172432871 m.
With a= 90% confidence interval on statistical tests, some
distance difference does not fall within the tolerance range (about 10%)
.. 3D visualization height Suramadu generated from the data Terrestrial
Laser Scanner more precise than those made of the data Total Station. In
the future, such as the visualization of 3D surface models can be used
for documentation, preservation and reconstruction of bridge building.
