Earth observation is a science and technology with tremendous power to collect data over the whole of the Earth at many wavelengths and at many spatial resolutions. But does this science and technology, or rather the use of this science and technology, have an ethical dimension? This article explores the application of ethical concepts to Earth observation. Three main aspects of ethics are examined: duty theories of ethics, consequentialist ethics, and environmental ethics. These ethical ideas are then applied to the UN Principles on Remote Sensing, the International Charter on Space and Major Disasters and to Google Earth, and also to questions of security and privacy. The article concludes that there is no absolute ethical position in relation to Earth observation, but a dependency on the perspective of the observer.
