Surveying Forest-Bat Communities with Anabat Detectors
Surveying bat populations and activity with ultrasonic bat detectors is a widespread practice in microchiropteran field research. We conducted tests on two aspects of bat detector use: vertical deployment of detectors and identification of species by call. The number of bat calls recorded from simultaneous bat detector surveys, conducted at tree canopy-level and at ground-level with Anabat II d...
متن کاملSynchronised Data Acquisition for Sensor Data Fusion in Aerial Surveying
An existing facility for data acquisition in aerial surveys is presented. It contains a laser radar, an infrared camera and a video camera. The system supports synchronisation of sensor data, even when the sensor does not inherently offer that feature. This allows data from different sensors to be merged and processed together. The necessary temporal referencing is achieved by specialised hardw...
متن کاملLow Cost Surveying Using an Unmanned Aerial Vehicle
Traditional manned airborne surveys are usually expensive and the resolution of the acquired images is often limited. The main advantage of Unmanned Aerial Vehicle (UAV) system acting as a photogrammetric sensor platform over more traditional manned airborne system is the high flexibility that allows image acquisition from unconventional viewpoints, the low cost in comparison with classical aer...
متن کاملUnmanned Aerial Vehicles (UAVs) for Surveying Marine Fauna: A Dugong Case Study
Aerial surveys of marine mammals are routinely conducted to assess and monitor species' habitat use and population status. In Australia, dugongs (Dugong dugon) are regularly surveyed and long-term datasets have formed the basis for defining habitat of high conservation value and risk assessments of human impacts. Unmanned aerial vehicles (UAVs) may facilitate more accurate, human-risk free, and...
متن کاملMonitoring Urban Development of Small Chinese Cities Using Innovative Aerial Surveying Technologies
Beside the enormous grow of Chinas mega-cities, also small cities and big villages show up an urban sprawl that makes a monitoring essential. Especially in the eastern part of the country, forced by the economic growth, the sprawl of urban fabric is extreme. This causes a need for a frequently and rapid monitoring in order to take pace in mapping and documentation. The typical turn rate of coun...
