Abstract
Abstract. Natural disasters as well as major man made incidents are an increasingly serious threat for civil society. Effective, fast and coordinated disaster management crucially depends on the availability of a real-time situation picture of the affected area. However, in situ situation assessment from the ground is usually time-consuming and of limited effect, especially when dealing with large or inaccessible areas. A rapid mapping system based on aerial images can enable fast and effective assessment and analysis of medium to large scale disaster situations. This paper presents an integrated rapid mapping system that is particularly designed for real-time applications, where comparatively large areas have to be recorded in short time. The system includes a lightweight camera system suitable for UAV applications and a software tool for generating aerial maps from recorded sensor data within minutes after landing. The paper describes in particular which sensors are applied and how they are operated. Furthermore it outlines the procedure, how the aerial map is generated from image and additional gathered sensor data.

Summary
AND MOTIVATIONHumanitarian relief in case of major disasters is a global task. Several international organizations and institutes take specific actions for its coordination and execution.1.1 GLOBAL ORGANIZATIONThe Office for the Coordination of Humanitarian Affairs (OCHA1) is part of the United Nations (UN) secretariat and is responsible for bringing together humanitarian actors to ensure a coherent response to emergencies, such as earthquakes, typhoons or conflicts. OCHA’s mission is to mobilize and coordinate effective humanitarian action in partnership with national and international actors in order to alleviate human suffering in disasters and emergencies. Towards major disasters OCHA ascertain the humanitarian needs of the affected government and is coordinating international relief actions. Rapid-response tools are served as well such as the United Nations Disaster Assessment and Coordination (UNDAC2) system and the International Search and Rescue Advisory Group (INSARAG3). UNDAC is part of the international emergency response system for sudden-onset emergencies and assessment teams can be deployed at short notice (12-48 hours) anywhere in the world. They are provided free of charge to disasteraffected countries. In case of sudden-onset emergency UNDAC installs an On-Site-Operations-Coordination-Center (OSOCC) and a Reception-Departure-Centre (RDC) for coordinating all
