The local costs of remote sensing: Examining the ethics of laser scanning in tropical forests

Laser scanning, often referred to as lidar, has rapidly transformed how tropical forest regions are studied, monitored and understood across academic disciplines. The technology enables researchers to peer through dense forest canopies, rapidly providing high-resolution scans of the landscape below. This growing observational power is central to the scientific value of remote sensing technologies but also brings into focus the conditions, interests and power structures under which they are used.
