This paper describes how multisource satellite data and efficient image analysis may successfully be used to conduct rapid-mapping tasks in the domain of disaster crisis-management support. The German Aerospace Center (DLR) has set up a dedicated crosscutting service, which is so-called "Center for satellite-based Crisis Information" (ZKI), facilitate use its Earth-observation capacities service national international response major situations, humanitarian relief efforts, civil security...
Abstract. Human immediate response is contextualized into different time compartments reflecting the tsunami early warning chain. Based on available and evacuation quantified. The latter incorporates accessibility of safe areas determined by a hazard assessment, as well environmental demographic impacts speed properties assessed using Cost Distance Weighting GIS approach. Approximately 4.35 million Indonesians live in endangered southern coasts Sumatra, Java Bali have between 20 150 min to...
A critical requirement for an effective and coordinated response by public entities tasked with management, security, relief during large-scale events or natural disasters is the availability of current situational information. However, today there a lack comprehensive operational systems allowing near-real-time (NRT) collection, visualization, provision information larger areas. In this study methodological framework proposed, which allows NRT extraction visualization based on aerial image...
Large-scale events represent a special challenge for crisis management. To ensure that participants can enjoy an event safely and carefree, it must be comprehensively prepared attentively monitored. Remote sensing provide valuable information to identify potential risks take appropriate measures in order prevent disaster, or initiate emergency aid as quickly possible the of emergency. Especially, three-dimensional (3D) is derived using photogrammetry used analyze terrain map existing...
The provision of reliable and quick spatial information in case a crisis event is still crucial aspect regarding relief actions. Remote sensing data can be source large-scale up-to-date information. Within the Data4Human project, researchers users from NGOs jointly worked on crisis-related demand driven provision. In following paper, we take closer look two aspects project that provide with access to i) flood monitoring tool ii) damage assessment AI methodology. Both approaches were...
Abstract. Enhancing situational awareness in real-time (RT) civil protection and emergency response scenarios requires the development of comprehensive monitoring concepts combining classical remote sensing disciplines with geospatial information science. In VABENE++ project German Aerospace Center (DLR) tools are being developed by which innovative data acquisition approaches combined extraction as well generation dissemination products to a specific user. DLR’s 3K 4k camera system allow...
Flooding represents the most-occurring and deadliest threats worldwide among natural disasters. Consequently, new technologies are constantly developed to improve response capacities in crisis management. The remaining challenge for practitioner organizations is not only identify best solution their individual demands, but also test evaluate its benefit a realistic environment before disaster strikes. To bridge gap between theoretic potential actual integration into practice, EU-funded...
The fastest growing regional crisis is happening in West Africa today, with over 8 million people considered persons of concern. A culmination identity politics, climate-driven disasters, and extreme poverty has led to this humanitarian the region exacerbated by a lack political will misplaced media attention. current state art does not present sufficient investigations thematic spatial coverage news region. This paper studies as reported media, themes associated those locations, based on...
With the breakthrough of spatial resolution optical remote sensing images at sub-meter level and explosive development deep learning, geospatial object detection has achieved a growing interest in community. However, labeling large training datasets is still an expensive tedious procedure. This might lead to poor model generalization degraded network learning ability. To this end, weakly-supervised (WSDN) developed for by applying digital surface (DSM)-aided auto-labeling pre-trained learned...
Abstract. In order to analyse optical satellite images for maritime security issues in Near-Real-Time (NRT) an interactive graphical user interface (GUI) based on NASA World Wind was developed and is presented this article. Targets or activities can be detected, measured classified with tool simply quickly. The service uses images, currently taken from 6 sensors: Worldview-1 Worldview-2, Ikonos, Quickbird, GeoEye-1 EROS-B. GUI also handle SAR-images, air-borne UAV images. Software...
In the context of project OpSSERVE - Optical Satellite Services for EMSA (European Maritime Safety Agency) – European Space Imaging (EUSI) and German Aerospace Center (DLR) established first time a fully operational near real-time service to detect vessels maritime activities with optical satellite imagery . The was implemented in 2013 contribute situation awareness, e.g. order reduce risk accidents, marine pollution loss human life at sea. Since its activation 2007, EMSA's CleanSeaNet (CSN)...
