Unmanned above the clouds; [Unbemannt über den Wolken]

Abstract

This article discusses unmanned aerial platforms and their use for observing areas from above. Aerial systems can collect imagery and measurements for mapping, inspection and monitoring, often with flexibility in timing and coverage. To produce useful geospatial information, operators must consider flight planning, sensor capability, positioning accuracy, processing and validation. The topic highlights the relationship between aerial data acquisition and GIS workflows, where captured information is transformed into maps, models or measurements. It also points to the need for responsible operation and a clear understanding of the accuracy required by the intended application.
