Real-time monitoring of natural disasters, mass events, and large accidents with airborne optical sensors is an ongoing topic inresearch and development. Airborne monitoring is used as a complemental data source with the advantage of flexible dataacquisition and higher spatial resolution compared to optical satellite data. In cases of disasters or mass events, optical highresolution image data received directly after acquisition are highly welcomed by security related organizations like police and rescueforces. Low-cost optical camera systems are suitable for real-time applications as the accuracy requirements can be lowered in returnfor faster processing times. In this paper, the performance of low-cost camera systems for real-time mapping applications isexemplarily evaluated based on already existing sensor systems operated at German Aerospace Center (DLR). Focus lies next to thegeometrical and radiometric performance on the real time processing chain which includes image processors, thematic processors forautomatic traffic extraction and automatic person tracking, data downlink to the ground station, and further processing anddistribution on the ground. Finally, a concept for a national airborne rapid mapping service based on the low-cost hardware isproposed
