The acquisition of geospatial information by small UAV

The recent advances of MEMS devices(GPS, gyro and acceleration sensor) has made possible low-cost and miniaturization. Thereby, multi-copter mounted with these sensors have appeared.That it requires a high level of technology and knowledge in the handling of RC traditional helicopter,beginners to steer is difficult.To enable even beginners to get easily geospatial information of high-resolution by multicopter. In this study, we examined method of acquiring geospatial information(orthophoto, DSM, NDVI, and temperature distribution) by using small UAV.
