Drone mapping has been growing interest in marine ecosystem research. The lowcost,
quick and manageable as well as producing precise maps are considered
advantages of this method. This study introduces a novel technique of aerial
photography using a drone for mapping the coral reefs in the coastal waters of Pulau
Rusukan Kecil, Labuan, Malaysia. A total of 616 overlapped aerial images captured
(592 were selected to use), mosaicked and geo-corrected using Agisoft Photoscan
image processing software. Afterwards, the corrected overall photos were stitched and
used to produce an orthophoto mosaic which undergone supervised and unsupervised
classification. A GIS-based topological thematic map generated as output and the
accuracy value calculated for supervised was 53.85% while 20.51% in 6 (dead coral,
coral, rock, sand, macro algae and rubble) and 23.58% in 12 classes for unsupervised.
This method believed as a highly possible method than the conventional method used
for further research related to marine ecosystem monitoring.
