An Augmented Reality Facility to Run Hybrid Physical-Numerical Flood Models
This article presents a novel installation for the development of hybrid physical-numerical flood models in an augmented reality environment. This installation extends the concept introduced by the well-known Augmented Reality-SandBox (AR-Sandbox) module, which presents a more educational, and less research-based and professional application. It consists of a physical scale topography built in a sandbox into which other elements (such as buildings, roads or dikes) can be incorporated. A scanner generates, in real time, a Digital Terrain Model (DTM) from the sandbox topography, which serves as a basis for the simulation of overland flow using professional hydraulic software (Iber+). The hydraulic and hydrological parameters (surface roughness, inlet discharges, boundary conditions) are entered with a simple Graphical User Interface (GUI) developed specifically for this project, as indeed was the entire system that allows the visualization of the simulation results. This allows us to obtain quantitative results of flood extension and magnitude, which are represented directly over the physical topography, yielding a realistic visual effect. This installation is conceived for both educational and professional uses. An example of its use is presented, through which its accuracy can be appreciated, and which also illustrates its potential.
An Immersive System for 3D Floods Visualization and Analysis
2018
Climate change has serious implications on our environment. Examples of such natural risks are massive rainfalls and the rise of ocean levels. Millions of people are exposed to the risk of extreme floods and storms. It is therefore crucial to develop analytical tools that allow us to evaluate the threats of floods and to investigate the influence of mitigation and adaptation measures, such as stronger dikes, adaptive spatial planning, and flood disaster plans. The objective of our work is to present a flood management system that aims to model and visualize floods. It provides realistic images to help users in understanding and interpreting these disaster scenarios. In order to investigate the applicability in practice, we illustrated the use of our system for real-world data in a case study for the city of Paris, France.

This study presents a systematic review of the literature on virtual reality (VR), augmented reality (AR) and Mixed Reality (MR) used in disaster management. We consider the factors such as publication type, publication year, application domain, and technology used. We surveyed papers from 2009 to 2019 available in the Web of Science and Google Scholar database, and 84 research articles were selected for the review study. After an extensive review of the literature, it was found that the XR technology is applied extensively in computer simulation modeling, interaction techniques, training, infrastructure assessment and reconnaissance, and public awareness areas of disaster management. We found diverse advantages, opportunities, and challenges of XR usage for disaster management, which are discussed in detail. Furthermore, current research gaps in the field of XR technology for disaster management technology, which are needed to better support disaster management, are identified and ...
Flood Emergency Interaction and Visualization System
Visual Information Systems. …, 2008
In this paper we describe a visualization system for an emergency simulation. We start by presenting a flooding emergency case scenario and all the elements that are involved in it. Then we describe the design decisions that were made in order to create a credible representation of the scene. This includes using a game engine to render the scenario using a three-dimensional terrain, with objects and information retrieved from geographic information systems. Additionally we describe experiments with new touch and tangible devices that support a war table like interaction with the simulation. We further describe our ideas for the emergency interface and conclude describing the directions for future work.
3D Applications in Disaster Mitigation and Management: Core Results of Ditac Project
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
According to statistical data, natural disasters as well as the number of people affected by them are occurring with increasing frequency compared to the past. This situation is also seen in Europe Union; So, Strengthening the EU capacity to respond to Disasters is very important. This paper represents the baseline results of the FP-7 founded DITAC project, which aims to develop a holistic and highly structured curriculum for responders and strategic crisis managers. Up-to-date geospatial information is required in order to create an effective disaster response plan. Common sources for geospatial information such as Google Earth, GIS databases, and aerial surveys are frequently outdated, or insufficient. This limits the effectiveness of disaster planning. Disaster Management has become an issue of growing importance. Planning for and managing large scale emergencies is complex. The number of both victims and relief workers is large and the time pressure is extreme. Emergency response and triage systems with 2D user interfaces are currently under development and evaluation. Disasters present a number of spatially related problems and an overwhelming quantity of information. 3D user interfaces are well suited for intuitively solving basic emergency response tasks. Such tasks include commanding rescue agents and prioritizing the disaster victims according to the severity of their medical condition. Further, 3D UIs hold significant potential for improving the coordination of rescuers as well as their awareness of relief workers from other organizations. This paper describes the outline of a module in a Disaster Management Course related to 3D Applications in Disaster Mitigation and Management. By doing this, the paper describes the gaps in existing systems and solutions. Satellite imageries and digital elevation data of Turkey are investigated for detecting sites prone to natural hazards. Digital image processing methods used to enhance satellite data and to produce morphometric maps in order to contribute to the detection of causal factors related to landslides, local site conditions influencing and/or experiencing earthquake damage intensity or those of tsunami and storm surge hazard sites at the coasts.
3D visualization tool for virtual models of natural disasters
2007
Visualization of large realistic forests, various countries, floods, fire spreads and landslides is very difficult and requires using of perfect modern graphic methods which allow rendering them as scenes in real time. This paper describes the creation of 3D visualization tool for visualization of natural disasters. A lot of international projects oriented on natural disasters utilise grid computing and within grid solution raises requirement of visualization service for presentation of the results. Such service requires unified standards like integration of input data formats and especially creation of unified visualization tool. It should integrate visualization requests of any kind of application oriented on computing of natural disasters. In case it is grid computing it has to be established also submit workflow, which controls execution of this visualization service. Development of all executable modules and solution of all above mentioned grid computing specific problems was subject of our scientific work presented in this article. The 3D visualization tool as well as submit workflow were tested on the applications solved in project MEDIGRID and on natural disasters applications solved in our institute [12].
Challenges of Using Drones and Virtual/Augmented Reality for Disaster Risk Management
ISPRS - International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Natural and man-made disasters can severely destroy environments and they make conditions difficult to access the affected areas and to provide assistance. The conditions on-site could be dangerous and unstable and there is an increasing need for life-saving decisions to be taken quickly to minimize evolving hazards and to start relief operations. The accurate and timely data gathering is important to produce a full information about the calamity. In recent disasters drones are deployed extensively to help find people quickly, provide imminent reliable imagery and data by flying closer to the ground. They are used to create disaster maps and assess damage after earthquakes, landslides, hurricanes, etc. The fast transition into the digital age makes new technologies become available to enhance and expand drone capabilities in disaster risk management, such as Virtual Reality (VR) and Augmented Reality (AR). The paper tries to analyze how VR can be used to plan operations in a controlled manner before deadly events strike by creating disaster simulations in digital environments, enabling the rescuers to practice as many times as necessary until they are able to achieve mastery of the life-saving techniques. The paper also analyzes how drones, equipped with cameras, devices and AR, can be used to create different types of maps that help rescuers locate critical spots. These can also facilitate the location of people in need, and can survey constructions to find critical damages.
This paper presents a new technology and a systematic approach for disaster response and recovery of Critical Physical Infrastructures (CPIs). Our suggested approach is based on using a Mobile Workstation Chariot (MWC) assembled on Segway personal transporter which supports both horizontal and vertical real-time visual data capture and transmission flow, first responders and civil engineers can quickly traverse hazardous terrain, collect and transmit photographs/videos, and communicate with the command center in real-time. Using MWC wireless communication tools, first responders and civil engineers can access disaster-survivable black boxes allowing Building Information Models (BIM), pre-disaster photographs and operational information of buildings to be collected and communicated back to the command center. Finally at the command center, using sensed visual data and image-based reconstruction techniques, the post-disaster site is reconstructed in 3D. The resulting integrated representation of the post-disaster model and the collected photographs are superimposed over the pre-disaster BIM to generate a 4D Augmented Reality (D 4 AR) model. By integrated representation of pre-disaster and post-disaster information, the D 4 AR allows damages, safety and stability of the CPIs as well as possible rescue operation routings and plans to be assessed. Critical information for disaster response and recovery can be analyzed and communicated back to the field easily and quickly. We present preliminary results of our experiments for collecting, analyzing, and visualizing sensed data using the MWC as well as the D 4 AR. These results demonstrate a great potential for application of MWC and D 4 AR for disaster response and recovery operations. The limitation and benefits of this approach plus further required developments are discussed.
Interactive Landscape Design and Flood Visualisation in Augmented Reality
Multimodal Technologies and Interaction
In stakeholder participation workshops, digital and hard-copy maps, alongside other representation formats in 2D and 3D, are used extensively to support communication, spatial evaluation and interactive decision making processes. In this paper, we present a novel tool to enhance traditional map-based workshop activities using augmented reality. Augmented reality technology is gaining momentum as a tool for visualising environmental design choices in planning and design, and is used in a range of applications including stakeholder participation, design evaluation and flood risk communication. We demonstrate interactive and collaborative 3D cartographic visualisations which enable real-time multi-user exercises in landscape intervention design and flood visualisation.
