Knowledge in (Geo)Visualisation: The relationship between seeing and thinking

Modern research in geovisualisation has framed the discipline as a field more akin to geovisual analytics - one that pleaces an emphasis on the human elements of exploration of data through interactive and dynamic geo-interfaces, rather than simple data representation. This rephrasing highlights the importance of cognitive aspects of human interaction with geo-based data and the interfaces designed to present them. In an attempt to provide a psychological background to the benefits of geovisual analytics, this paper will explroe the role that perception hasi n complex problem solving and knowledge discovery, and will demonstrate that, through modern interactive technologies, (geo)visualiations augment and facilitate our natural ability to surface novel, surprising and otherwise invisible relationships between information. It will argue that it is through these novel relationships that we add to our understandings of the original information and simultaneously reveal new knowledge 'between the gaps'

Rerouting Framework for Sustainable Management in Elephant Conservation

: Human-Elephant Conflict (HEC) has been identified as one of the major threats to wild elephants through its range in thirteen countries including Malaysia. With development encroaching into the elephant’s natural territories, the number of HEC cases has increased. The aim of this study is focusing on developing a framework of elephant rerouting and causeway using geomatics technology and 3D Geo-visualisation as strategy to conserve elephant in sustainable way for Taman Negara Rompin. The framework was used to propose alternative pathway based on rational model. Four main elements strongly highlighted in the rerouting framework are elephant diet’s sources, tracking trail, fencing and deterrents and the corridors monitoring. With the integration of Geographical Information system, the knowledge to protect elephants from HEC can be enhanced

Determination of electromagnetic field exposure in public spaces

The monitoring of electromagnetic (EM) field, caused by the presence of radio frequency (RF) and microwave radiation from ICT devices as various sources of EM field, has emerged as an important technical and social challenge in terms of planning, management and usage of open public spaces. Considering the necessity of EM field level determination in the context of using ICT devices in service areas, as well as monitoring of EM field exposure in public spaces, the several technical issues have been foreseen in the analyses based on corresponding examples: from the method for modelling of EM field propagation in the vicinity of RF and microwave sources - base stations for mobile networks, broadcasting transmitters, local wireless networks, together with the distribution of EM field from ICT devices, through the appropriate measurement and exposure assessment methods, to the adequate software support for geo-visualisation, the data acquisition and processing.Funded by the Horizon 2020 Framework Programme of the European Union.peer-reviewe

The potential of integrating E-participation in planning support systems

The increasing complexity of spatial planning issues and pressure from citizens to takepart in designing and deciding on spatial plans result in a need for improved methods to aidcommunication between governmental actors and citizens. These developments put high demands onparticipatory Planning Support Systems (PSS); instruments that can aid planners in doing theirplanning tasks. By using the accessibility of the internet, e-participation offers opportunities as a PSS.Although many advantages are attributed to participatory PSS, its use in the planning practice remainsmarginal until now. It is argued here that this is partly caused by the lack of empirical studies thatdemonstrate potential benefits and problems when applying PSS. This paper provides guidelines fororganizations that contemplate on using a participatory PSS. In order to do so, a framework isdeveloped, identifying obstacles that could block effective participation in a PSS. Three planningprocesses are evaluated to investigate the importance of these obstacles. It is demonstrated that,although e-participation has potential as PSS, the lack of political will blocks effective participationand a more profound link between the citizen input and the decision-making is neede

The Etruscans in 3D: From Space to Underground

eomatics and Geoinformatics deal with spatial and geographic information, 3D surveying and modeling as well as information science infrastructures. Geomatics and Geoinformatics are thus involved in cartography, mapping, photogrammetry, remote sensing, laser scanning, Geographic Information Systems (GIS), Global Navigation Satellite Systems (GNSS), geo-visualisation, geospatial data analysis and Cultural Heritage documentation. In particular the Cultural Heritage field can largely benefit from different Information and Communication Technologies (ICT) tools to make digital heritage information more informative for documentation and conservation issues, archaeological analyses or virtual museums. This work presents the 3D surveying and modeling of different Etruscan heritage sites with their underground frescoed tombs dating back to VII-IV century B.C.. The recorded and processed 3D data are used, beside digital conservation, preservation, transmission to future generations and studies purposes, to create digital contents for virtual visits, museum exhibitions, better access and communication of the heritage information, etc

GEO-VISUALISATION AND VISUAL ANALYTICS FOR SMART CITIES: A SURVEY

Geo-Visualisation (GV) and Visual Analytics (VA) of geo-spatial data have become a focus of interest for research, industries, government and other organisations for improving the mobility, energy efficiency, waste management and public administration of a smart city. The geo-spatial data requirements, increasing volumes, varying formats and quality standards, present challenges in managing, storing, visualising and analysing the data. A survey covering GV and VA of the geo-spatial data collected from a smart city helps to portray the potential of such techniques, which is still required. Therefore, this survey presents GV and VA techniques for the geo-spatial urban data represented in terms of location, multi-dimensions including time, and several other attributes. Further, the current study provides a comprehensive review of the existing literature related to GV and VA from cities, highlighting the important open white spots for the cities’ geo-spatial data handling in term of visualisation and analytics. This will aid to get a better insight into the urban system and enable sustainable development of the future cities by improving human interaction with the geo-spatial data

Graphic study and geovisualization of the old windmills of La Mancha (Spain)

In Spain, one can find geographical diversity and unique sites of great significance and cultural heritage. Many of the nation’s treasured places, however, have deteriorated or have even disappeared. What is left, then, should be studied and documented both graphically and infographically. It is important to preserve and document Spain’s unique locations, especially those related to vernacular heritage, to transhumance and visual impact assessment in many national infrastructures projects. Windmills are important examples of agro-industrial heritage and are sometimes found in the beds of streams and rivers but can also be found high in the hills. Their presence is constant throughout the Iberian Peninsula. These mills are no longer in use due to technological advances and the emergence of new grinding systems. The aim of this study was to present a specific methodology for the documentation of windmills, to create a graphical representation using computer graphics, as well as to disseminate knowledge of this agro-industrial heritage. This research has integrated graphic materials, including freehand sketches, photographs, digital orthophotos, computer graphics and multimedia in the creation of a specific methodology based on cutting-edge technology such as a digital photogrammetric workstation (DPW), global navigation satellite systems (GNSS), computer-aided design (CAD) and computer animation
