| Summary: | The coastline is used in determining regional sea boundaries and used as a reference
for baseline to determining state maritime boundaries. The available shoreline
information is mostly not updated. Thus coastline mapping is needed to get the latest
coastline. Coastline mapping can use UAV(Unmanned Aerial Vehicle) technology,
with advantages in terms of time, finance, and workmanship.
This study aims to determine the coastline from aerial photo data with the influence of
tidal data. Photo acquisition was carried out in the study area of Ujung Genteng Beach,
with three acquisition sessions with momentary water levels: high water level, average
water level, and low water level. Processing of aerial photo data forms orthophoto and
DEM for each session. DEM data is processed into DTM which is then processed into
coastal slope. Tidal data processing with TPXO9 tide model to determine fixed water
level values: LAT, HAT, and MSL to obtain tidal correction. Determination of the
coastline using the water and land boundary delineation method from the results of the
digital classification of each orthophoto. The delineated coastline is corrected using
tide corrections and coast slope. Validation of the corrected coastline using coastline
in nautical map and topographic map.
The result of this research is that the coastline is corrected with the influence of tidal
data in the form of coastlines of LAT, HAT, MSL and chart datum lines. Validation
of the coastline obtained a difference of up to 10-20 m, the difference meets the
accuracy according to Regulatory Head of Geospatial Information Agency no. 15/2014
about Accuracy of Base Maps. The validation results prove that the shoreline results
are included in the accuracy requirements. Thus, the coastline results can be used as a
revision of the Ujung Genteng coastline on an existing map
