using mapping drones for disaster prevention & response
DESCRIPTION
Adam Klaptocz of Drone Adventures and senseFly explains how autonomous mapping drones (UAVs) can help NGOs and similar organisations to make better decisions - using the latest drone technology to take high-resolution aerial photographs of at-risk areas and disaster zones, before transforming these shots into accurate 2D 'orthomosaics' (maps) and 3D models.TRANSCRIPT
