To enhance existing strategies for controlling the Aedes aegypti mosquito, geoinformation scientist Dr Steffen Knoblauch has created a high-resolution environmental suitability map for Rio de Janeiro (Brazil) that can help identify areas most conducive to breeding. It is based on advanced geospatial big data methods – leveraging openly available geodata such as satellite imagery, street view images, and climate data – that the researcher developed at Heidelberg University’s Interdisciplinary Center for Scientific Computing (IWR) and at HeiGIT (Heidelberg Institute for Geoinformation Technology).
