abstract = "The objective of the present study, developed in a mountainous
region in Brazil where many landslides occur, is to present a
method for detecting landslide scars that couples image processing
techniques with spatial analysis tools. An IKONOS image was
initially segmented, and then classified through a Batthacharrya
classifier, with an acceptance limit of 99%, resulting in 216
polygons identified with a spectral response similar to landslide
scars. After making use of some spatial analysis tools that took
into account a susceptibility map, a map of local drainage
channels and highways, and the maximum expected size of scars in
the study area, some features misinterpreted as scars were
excluded. The 43 resulting features were then compared with
visually interpreted landslide scars and field observations. The
proposed method can be reproduced and enhanced by adding filtering
criteria and was able to find new scars on the image, with a final
error rate of 2.3%.",
