  2. 1. Ontology as Conceptual Schema when Modelling Historical Maps for Database Storage

    Author : Gustaf Svedjemo; Erland Jungert; Wollter Arnberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; ontology; historical maps; database modelling; GIS; Geographical Information Systems; archaeology; history; ontologi; historiska kartor; databasmodellering; GIS; geografiska informationssystem; arkeologi; historia; Computer science; Datavetenskap; History subjects; Historieämnen;

    Abstract : Sweden has an enormous treasure in its vast number of large-scale historical maps from a period of 400 years made for different purposes, that we call map series. The maps are also very time and regional dependent with respect to their concepts. A large scanning project by Lantmäteriverket will make most of these maps available as raster images. READ MORE

  4. 2. Analytical tools and information-sharing methods supporting road safety organizations

    Author : Imad Abugessaisa; Erland Jungert; Kenneth Asp; Åke Sivertun; Josef Mikulik; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visual data mining; STRADA; GLOBESAFE; Conceptual model; System thinking; Internet GIS; Computer science; Datavetenskap;

    Abstract : A prerequisite for improving road safety are reliable and consistent sources of information about traffic and accidents, which will help assess the prevailing situation and give a good indication of their severity. In many countries there is under-reporting of road accidents, deaths and injuries, no collection of data at all, or low quality of information. READ MORE

  5. 3. A visual query language served by a multi-sensor environment

    Author : Karin Camara (Silvervarg); Erland Jungert; Genaro Costagliola; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; query language; command and control; spatial; temporal; uncertainty; sensor data independance; visual query language; sensor data source; Computer science; Datavetenskap;

    Abstract : A problem in modern command and control situations is that much data is available from different sensors. Several sensor data sources also require that the user has knowledge about the specific sensor types to be able to interpret the data. READ MORE

  6. 4. Exploring Tactical Command and Control : A Role-Playing Simulation Approach

    Author : Jiri Trnka; Erland Jungert; Björn Johansson; Tim Grant; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis concerns command and control (C2) work at the tactical level in emergency and crisis response operations. The presented research addresses two main research questions. The first question is whether it is feasible to simulate and study C2 work in the initial stages of response operations by means of role-playing simulations. READ MORE

  7. 5. Prerequisites for data sharing in emergency management : joint analysis using a real-time role-playing exercise approach

    Author : Jiri Trnka; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : This thesis explains how semi-coordinated or separated utilization of information and communication technologies may affect collaborative work between different emergency management organizations, and their capabilities to perform joint tasks during emergency responses. Another aim is to explore the modeling of emergency management and data collection methods with respect to utilization of these technologies. READ MORE
