A team from Department of Civil and Geomatics Engineering, went out to the Kuttal village of Dhulikel municipality, and Panga and Itagol of Kirtipur municipality to collect the data about the damage caused due to devastating earthquake on April 25th, 2015. The team used emerging technology of Unmanned Aerial Vehicle, which the Geospatial Lab has been using for the Biomass Estimation Research Project here at Kathmandu University. The team collected the aerial images of these places with the Sony Digital Camera mounted on the UAV. The team deployed self-assembled hexacopter as a sensor carrier for serving the purpose.
The UAV flights were conducted in the first week of May, 2015. The team collected aerial images of these places using the digital camera mounted on the hexacopter. The camera mounted on the UAV was Sony Cybershot W120. The images were taken at the height of about 100m from the ground. The image overlap were 80% in the flight direction and 60% across the flight direction. The UAV has its inbuilt GPS and IMU so the location of camera position was recorded for each image along the flight.
