    Heritage graphic representation combining building spatial location and urban/land planning supports the decision-making of government agencies and simplifies the development of protection and conservation projects. The evolution of web-based open-source representation systems, able to store 3D graphics information and to make it accessible by web platforms, allows to develop novel heritage catalogues which simplify the exchange of information between administrations and citizens. This work is devoted to the creation of the Digital 3D Inventory of the Aragonese Mudéjar Architectural Heritage, a list of 225 buildings with unique architectural elements which are part of the UNESCO World Heritage. We propose a generalized methodology for collecting, store and disseminate friendly 2D geospatial and 3D geometric documentation of the historical buildings, ensuring that valuable information is stored and providing greater graphic and documentary resources than traditional inventories of architectural heritage. The main novelty is creation of a web platform which allows the exploitation of the architectural information through a cartographic webGIS viewer and a 3D environment based on webGL for rendering large point clouds. The proposed web platform enables to delivery 3D content through generic web browsers natively supported by all devices and without installing third-party applications neither downloading massive data files

    Seafloor characterization using airborne hyperspectral co-registration procedures independent from attitude and positioning sensors

    The advance of remote-sensing technology and data-storage capabilities has progressed in the last decade to commercial multi-sensor data collection. There is a constant need to characterize, quantify and monitor the coastal areas for habitat research and coastal management. In this paper, we present work on seafloor characterization that uses hyperspectral imagery (HSI). The HSI data allows the operator to extend seafloor characterization from multibeam backscatter towards land and thus creates a seamless ocean-to-land characterization of the littoral zone

    Generation of a digital archive of heritage, with drones in rural areas

    The enhancement of heritage, both cultural and natural, must be considered as a resource for revitalizing the territory. In this context, Aragon has a great landscape and cultural heritage that is scattered throughout the territory and is not very accessible. It needs to be properly documented and inventoried as a means of activating new processes of knowledge, enhancement and use of rural development. This work is devoted to the creation of the Digital 3D Inventory of the Aragonese Mudejar Architectural Heritage, which includes buildings that currently have little graphic and imprecise documentation, since many of them are located in small towns of less than 500 inhabitants, with urban fabric of narrow streets. To carry out the registration, the use of drones to capture images and later the construction of the point cloud with photogrammetry, it is an adequate technical and economically sustainable solution since it deals with populations plagued by depopulation and with few resources. A generalized methodology is proposed to collect, store and disseminate 2D/3D geometric and geospatial documentation of inventoried buildings, providing more graphic information than traditional architectural inventories. As a novelty, for the dissemination of information, the creation of a web platform composed of a cartographic viewer (WebGIS) and a point cloud manager based on WebGL technology is proposed as a valuable tool to relate buildings with their environment, characteristic of great importance in the case of heritage located in rural areas

    Proceedings of the 3rd Open Source Geospatial Research & Education Symposium OGRS 2014

    The third Open Source Geospatial Research & Education Symposium (OGRS) was held in Helsinki, Finland, on 10 to 13 June 2014. The symposium was hosted and organized by the Department of Civil and Environmental Engineering, Aalto University School of Engineering, in partnership with the OGRS Community, on the Espoo campus of Aalto University. These proceedings contain the 20 papers presented at the symposium. OGRS is a meeting dedicated to exchanging ideas in and results from the development and use of open source geospatial software in both research and education.  The symposium offers several opportunities for discussing, learning, and presenting results, principles, methods and practices while supporting a primary theme: how to carry out research and educate academic students using, contributing to, and launching open source geospatial initiatives. Participating in open source initiatives can potentially boost innovation as a value creating process requiring joint collaborations between academia, foundations, associations, developer communities and industry. Additionally, open source software can improve the efficiency and impact of university education by introducing open and freely usable tools and research results to students, and encouraging them to get involved in projects. This may eventually lead to new community projects and businesses. The symposium contributes to the validation of the open source model in research and education in geoinformatics

    A Web GIS-based Integration of 3D Digital Models with Linked Open Data for Cultural Heritage Exploration

    Get PDF
    This PhD project explores how geospatial semantic web concepts, 3D web-based visualisation, digital interactive map, and cloud computing concepts could be integrated to enhance digital cultural heritage exploration; to offer long-term archiving and dissemination of 3D digital cultural heritage models; to better interlink heterogeneous and sparse cultural heritage data. The research findings were disseminated via four peer-reviewed journal articles and a conference article presented at GISTAM 2020 conference (which received the ‘Best Student Paper Award’)

    A Bibliography on the Application of GIS in Archaeology and Cultural Heritage

    Get PDF
    Geographical Information Systems (GIS) applications to archaeological projects of different scales, chronological contexts and cultural milieux has accrued by now a long history and bibliography. Hopefully the phases of experimentation and almost blind testing are over, even if GIS applications are still sometimes being labeled as “new technologies”
