Towards a virtual hub approach for landscape assessment and multimedia ecomuseum using multitemporal-maps

Landscapes are dynamic entities, stretching and transforming across space and time, and need to be safeguarded as living places for the future, with interaction of human, social and economic dimensions. To have a comprehensive landscape evaluation several open data are needed, each one characterized by its own protocol, service interface, limiting or impeding this way interoperability and their integration. Indeed, nowadays the development of websites targeted to landscape assessment and touristic purposes requires many resources in terms of time, cost and IT skills to be implemented at different scales. For this reason these applications are limited to few cases mainly focusing on worldwide known touristic sites. The capability to spread the development of web-based multimedia virtual museum based on geospatial data relies for the future being on the possibility to discover the needed geo-spatial data through a single point of access in an homogenous way. In this paper the proposed innovative approach may facilitate the access to open data in a homogeneous way by means of specific components (the brokers) performing interoperability actions required to interconnect heterogeneous data sources. In the specific case study here analysed it has been implemented an interface to migrate a geo-swat chart based on local and regional geographic information into an user friendly Google Earth^©-based infrastructure, integrating ancient cadastres and modern cartography, accessible by professionals and tourists via web and also via portable devices like tables and smartphones. The general aim of this work on the case study on the Lake of Como (Tremezzina municipality), is to boost the integration of assessment methodologies with digital geo-based technologies of map correlation for the multimedia ecomuseum system accessible via web. The developed WebGIS system integrates multi-scale and multi-temporal maps with different information (cultural, historical, landscape levels) represented by thematic icons allowing to transfer the richness of the landscape value to both tourists and professionals

Harmonization of categorical maps by alignment processes and thematic consistency analysis

Nicolau, R., Basos, N., Marcelino, F., Caetano, M., & M. C. Pereira, J. (2020). Harmonization of categorical maps by alignment processes and thematic consistency analysis. AIMS Geosciences, 6(4), 473-490. https://doi.org/10.3934/geosci.2020026This paper describes an approach for harmonizing historical vector categorical maps with related modern maps. The approach aims at the correction of geometric distortions and semantic disagreements using alignment processes and analysis of thematic coherence. The harmonized version of the map produced by this approach can already be overlaid with other maps, what was unfeasible with the original map. The positional errors of the old map are reduced by two consecutive geometric adjustments, which use transformations usually available in most GIS software. The thematic consistency between the old and the modern map is achieved by harmonizing their classification systems and by the inclusion of specific contents missing in the early map, but represented in the modern map (e.g. small rivers). This approach was tested in the geometric and thematic harmonization of the Portuguese Land Cover/Land Use (LCLU) map for 1990 (COS90). In this test, the 1995 orthorectified aerial images and the 1995 LCLU map (COS95) were used as reference sources of higher positional accuracy, to align the COS90 map. COS90 was firstly adjusted with the 1995 aerial images by an NTV2 grid transformation, developed by the authors. Then, for reduction of the local distortions, the map resulting from the first transformation was aligned with the COS95 by a rubber-sheeting linear interpolation transformation. This geometric harmonization enabled a decrease of the Root Mean Square Error of COS90 from 204 meters to 13 meters. The thematic harmonization of COS90 enabled its comparison with modern related maps, and the integration of 201 river sections, that were missing because the specifications used in the production of the original map did not allow their representation.publishersversionpublishe

Museos virtuales y entorno construido: narrativas y experiencias inmersivas vía centros de geodatos multitemporales

[EN] Our built environment is nowadays considered as a dynamic complex, stretching and transforming across space and time, with the interaction of human, social and economic dimensions. It needs to be safeguarded as living places for the future taking into account such complexity. The general aim of this work is to contribute to the comprehension of landscape values, enhancing participation processes by tourists and local communities, considering the built environment as a system: the sum of natural transformation, ancient artefacts stratification and human activities, partially covering the tangible traces, and functioning as a vehicle for the comprehension of intangible values. Multi-temporal, multi-scale and geospatial datasets can play an important role in such knowledge transfer processes by means of narratives and immersive experiences in a multimedia museum approach. In particular, the cartographic heritage, in the form of metric and non-metric maps, can be progressively used as a source of information for innovative narratives. Virtual Museums (VMs)are additional "channels" to disseminate content and to provide knowledge about cultural heritage; they have emerged from the crossbreeding process between museums and digital technologies. Investigating how digital storytelling may support communication and understanding of complex systems, such as the built environment and landscape, it is relevant because cultural awareness may foster the sense of belonging and identity construction of which Europe is thirsty, contributing to the safeguarding of fragile sites. The paper provides useful information for museums that would like to follow this pathway. It retraces the main steps of storytelling production and presents interesting examples of immersive narrative models based on geospatial data and a virtual hub, helping people to retrieve and access information and to recognize places of memory mostly unknown. Moreover, it offers an evaluation of existing tools that can be adopted for this purpose. Eventually, by virtue of the research carried out for the case study of the Virtual Museum of Como Lake Landscape, the paper aims at ascertaining which kind of stories and experiences can be designed, the potential of these tools and possible weaknesses or constraints that deserve future researches.[ES] El entorno construido se considera hoy en día como un complejo dinámico, que se extiende y transforma a través del espacio y el tiempo, con interacción de dimensiones humanas, sociales y económicas. Debe salvaguardarse como lugares donde vivir el futuro teniendo en cuenta tal complejidad. El objetivo general de este trabajo es contribuir a la comprensión de los valores paisajísticos, potenciando los procesos de participación de los turistas y de los autóctonos, considerando el entorno construido como un sistema: suma de la transformación natural, de la estratificación de artefactos antiguos y de actividades humanas, cubriendo parcialmente los rastros tangibles, y vehículo de comprensión de valores intangibles. Los conjuntos de datos multitemporales, a multi-escala y geoespaciales pueden desempeñar un papel importante en dicho proceso de transferencia de conocimiento a través de narrativas y experiencias inmersivas en el enfoque de un museo multimedia. En particular, el patrimonio cartográfico, en forma de mapas métricos y mapas no métricos, puede utilizarse progresivamente como fuente de información para narrativas innovadoras. Los Museos Virtuales (VM) son “canales” adicionales que permiten difundir contenido y proporcionar conocimiento sobre el patrimonio cultural; surgen del proceso de mestizaje entre museos y tecnologías digitales. Investigar cómo la narración digital puede apoyar la comunicación y la comprensión de sistemas complejos, como el entorno construido y el paisaje, es relevante porque la conciencia cultural puede fomentar el sentido de pertenencia y la construcción de identidad de los que Europa tiene sed, contribuyendo a la protección de sitios frágiles. El artículo proporciona información útil para los museos que deseen seguir este camino. Describe los principales pasos que deberían considerarse a la hora de producir narrativas y pone ejemplos interesantes de modelos narrativos inmersivos basados en datos geoespaciales y centros virtuales, que ayudan a las personas a recuperar y acceder a información, y a reconocer lugares desconocidos o vagamente retenidos en la memoria. Además, ofrece una evaluación de las herramientas existentes que se pueden adoptar con este propósito. El objetivo es aclarar, finalmente, en virtud dela investigación desarrollada en el caso de estudio del Museo Virtual del Paisaje del Lago di Como, qué tipo de historias y experiencias se pueden diseñar, el potencial de estas herramientas y las posibles debilidades o limitaciones que merecen futuras investigaciones.We thank Stefano Della Torre (Head of Polimi dABC) as Sc.

Virtual museums and built environment: narratives and immersive experience via multi-temporal geodata hub

open4Our built environment is nowadays considered as a dynamic complex, stretching and transforming across space and time, with the interaction of human, social and economic dimensions.
