The Development of Interpretataion Method For Remote Sensing Imagery In Determining The Candidate of Landslide In Leitimur Paninsula, Ambon Island
ABSTRACT: Remote sensing is
one of the methods used to address the problem of research on spatial data
acquisition technologies and is also acquiring the problems of territorial and
land resource management. The utilization of remote sensing method for the
landslide research is visual and digital imagery interpretation. The purpose of
this study was to compare the accuracy of the method of interpretation and
determine the location of the landslide event. The imagery that used in this study
was Landsat 8, Quickbird and SRTM. The method that used to determine the
candidate of landslide was the layered visual interpretation, digital imagery
interpretation with NDVI, OBIA, Toposhape, and combination-OBIA NDVI and
NDVI-OBIA-Toposhape. The use of the interpretation method for the landslide
event is the best of layered-visual interpretation with a percentage of 90%.
Digital interpretation with NDVI has a 47% of its accuracy, thoroughness OBIA
45%, Toposhape 47%, the combination of NDVI-OBIA 47%, and the combination of
NDVI-OBIA-Toposhape 53%. From the
layered-visual interpretation and field observations were obtained type of
landslide found that soil rotational slide in large quantities 7 points
(38.9%), creep soil (soil creep), the flow of material destruction (debris
flow), landslides translation with soil materials (earths slide) and multiple
rotational slide.
