Identification of flood-prone area using remotely sensed data - Case in Tanjung Selor City, North Kalimantan

This research was conducted in Tanjung Selor area as a new city in North Kalimantan, Indonesia. It is aimed at analyzing flood-prone area based on high resolution image data. The area was sensed by a compact digital camera installed on Unmanned Aerial Vehicle (UAV).
