Title: Airborne LIDARDerived Digital Elevation Models for Characterizing Active Faults and Landslide Proces
1Airborne LIDAR-Derived Digital Elevation Models
for Characterizing Active Faults and Landslide
Processes
- We successfully organized an airborne LIDAR
mapping team to generate high-resolution digital
elevation models in the Taiwan region. Among our
published research results related to the LIDAR
work are (1) Analyzing fault activities around
the Hsinchu industrial park based on detailed
morphologic features, and indicating that the
nearby Hsincheng fault to be an earthquake threat
to the region. (2) Deriving earthquake-induced
landslide volumes and erosion rates accurately
for the the Jioufenershan and Tsaoling
landslides, which differ greatly from previous
known estimations. (3) Identifying the
morphological structures along post-landslide
surfaces using the LIDAR images, which indicate
clear unstable features for future landslide
activities.
