Mapping trees, finding heat islands: Research drones offer many new options for small-scale observation of the environment. Earth observation, also known as remote sensing, provides highly relevant information about the state and change of our planet every day via satellite data worldwide. The data can be used, for example, to gather information about heat islands in cities, droughts or the condition of forests. Earth observation is currently opening up additional data sources: With sensors installed on commercially available drones, it is obtaining further detailed environmental information - and at a spatial resolution so high that it cannot be achieved with satellite data. "The very high resolutions in the centimetre range open up new areas of application and research questions," says scientist Dr Mirjana Bevanda from the Earth Observation Research Hub at Julius-Maximilians-Universität Würzburg (JMU), a merger of the JMU Chairs of Remote Sensing and Global Urbanisation and Remote Sensing.
