Data quality assessment of UAV-based products for land tenure recording in East Africa

Since the past two years, unmanned aerial vehicles (UAVs) are evolving as a mapping tool in African countries. However, conditions for flying, controlling and referencing respective data are more complex than in Europe and are often underestimated. Especially geometric accuracy and radiometry are negatively influenced by densely populated areas and adverse meteorological conditions. More than 40 datasets from 8 UAV field campaigns and demonstrations in Zanzibar, Rwanda and Kenya are used to conclude findings on opportunities and challenges to achieve high levels of data quality. The research is associated with the EU H2020 project “its4land”
