Is higher resolution always better? A comparison of open-access DEMs for optimized slope unit delineation and regional landslide prediction
No full textDigital elevation models (DEMs) play a key role in slope instability studies, ranging from landslide detection and recognition to landslide prediction. DEMs assist these investigations by reproducing landscape morphological features and deriving relevant predisposing factors, such as slope gradient, roughness, aspect, and curvature. Additionally, DEMs are useful for delineating map units with homogeneous morphological characteristics, such as slope units (SUs).In many cases, the selection of a DEM depends on factors like accessibility and resolution, without considering its actual accuracy. In this study, we compared freely available global elevation models (Advanced Land Observing Satellite (ALOS) World 3D-30m, Copernicus GLO-30 (COP), Forest And Buildings removed COP DEM (FABDEM)) and a national dataset (TINITALY) with a reference model (local airborne lidar) to identify the most suitable DEM for representing fine-scale morphology and delineating SUs in the Marche region, Italy, for landslide susceptibility studies. Furthermore, we proposed a novel approach for selecting the optimal SU partition.The DEM comparison was based on several criteria, including elevation, residual DEMs, roughness indices, slope variations, and the ability to delineate SUs. TINITALY, resampled at a 30mx30m pixel size, was found to be the most suitable DEM for representing fine-scale terrain morphology. It was then used to generate the optimal SU partition among 18 combinations. These combinations were evaluated using both existing and newly integrated metrics alongside mapped landslide inventories to optimize terrain delineation and contribute to landslide susceptibility studies
Gli anni della formazione = The formative years
No full textIl contributo ripercorre le vicende degli anni relativi alla formazione (1850-1860) del fotografo "veneziano" Antonio Beato a partire dall’incontro - a Costantinopoli all’inizio degli anni Cinquanta del 1800 - suo e del fratello Felice, con il loro futuro cognato, il fotografo ed incisore britannico James Robertson. Da quest'ultimo essi apprendono la tecnica, ma anche uno sguardo complesso e articolato che pone particolare attenzione all'architettura e alla città. In questo senso le loro fotografie hanno un valore paragonabile a quelle di altri pionieri della fotografia della seconda metà dell’Ottocento (quali Gustave Le Gray, Francis Frith, Maxime du Camp, Félix Bonfils, o i fratelli Zangaki), tuttavia non si può no notare come, con i loro scatti, essi non si limitino a catturare i magnifici resti delle architetture prodotte dalle antiche civiltà sorte ai margini orientali del Mediterraneo, ma arrivino anche a realizzare quelli che possono essere considerati dei veri e propri primi reportage di guerra. Così il testo si concentra sia sul viaggio che, partendo da Costantinopoli, i fratelli Beato e James Robertson compiono attraverso il Mediterraneo orientale tra il 1854 e il 1857, raggiungendo la Grecia, Malta, la Terra Santa e l'Egitto, sia su quello che, assieme o separatamente, essi compiono, tra il 1855 e il 1859, per documentare documentare ciò che avviene con la guerra di Crimea (1854-1856) e con la Prima guerra di liberazione indiana a Lucknow e Delhi (1857-1865)

No full textUrban narrative and peasant imaginaries in French hybrid territories: a perspective from the Vendée Bocage
No full textIn recent years, France has witnessed a renewed interest within urban studies in inhabited territories that are characterised by a hybridisation of urban and rural features. This interest has emerged in the face of new challenges linked to the agroecological transition process and the rise of new forms of peasant agriculture. This contribution brings together some reflections developed in the context of long-term research on the Vendée Bocage region in France, a territory historically characterised by urban-rural hybridisation rooted in agrarian logics. It focuses on analysing the urban narrative promoted by the recent planning regulatory framework, highlighting certain limits and countertrends linked to the living desires and imaginaries of a community of peasants associated with three local alternative food networks. Starting from these reflections, the contribution outlines some possible paths for the renewal of urbanism while embracing an agrarian perspective
Navigare nella Storia: tecnologie immersive per la valorizzazione delle Ville Venete lungo il fiume Brenta = Sailing through History: Enhancing the Venetian Villas along the Brenta River through Immersive Technologies
No full textLe Ville Venete lungo il fiume Brenta rappresentano un patrimonio storico di inestimabile valore, testimoni di un’epoca in cui architettura, paesaggio e cultura si intrecciavano in un equilibrio perfetto. Tuttavia, il passare del tempo e le trasformazioni territoriali hanno modificato in modo significativo il loro aspetto originario, rendendo spesso difficile una piena comprensione del loro contesto storico e architettonico. Il progetto Ville Venete Virtual Reality Boat (ViVe VR-Boat) si propone di superare questa difficoltà attraverso l’utilizzo combinato di diverse tecnologie digitali, offrendo una sintesi visiva che restituisca un’immagine coerente del paesaggio e delle architetture del XVIII secolo. L’integra- zione tra fonti storiche, rilievi diretti e realtà virtuale si configura come un modello innovativo non solo per la divulgazione culturale, ma anche per la conservazione e la valorizzazione del patrimonio storico, dimostrando il potenziale delle tecnologie immersive, come la realtà virtuale e aumentata, per la ricerca e la fruizione interattiva dei beni culturali
Between proximity-based social innovation and tourism: initiatives of micro-regeneration in the Po Delta and Polesine region
No full textFaced with pressing challenges including unemployment, depopulation, over-tourism, the erosion of social cohesion and the loss of collective identity, many local communities’ tourism initiatives include proximity-based forms of social innovation. These are often initiated by small-scale, bottom-up stakeholders - small entrepreneurs, family firms, cooperatives, museums, and social enterprises – and aim to preserve and enhance local cultural heritage in its diverse forms. Social innovation in tourism has become an increasingly relevant field of research, shedding light on how communities mobilize tangible and intangible cultural heritage to foster processes of micro-regeneration and sustainable local development. The chapter examines various case studies in the Po Delta and Polesine region, looking at stakeholders who are involved in promoting local cultural heritage. A qualitative approach has been employed, based on interviews and life-stories of key stakeholders involved in cultural heritage enhancement and narration. The goal is to explore how these professionals act as key agents to preserve and enhance the historical memory of their territories, generating benefits both for themselves, their local communities, while also launching micro-regeneration processes in the area
Indagini sullo spazio post-sovietico. Architetture religiose fra eredità e trasformazioni in Est Europa, Caucaso e Asia Centrale
No full textIl volume offre una riflessione inedita sullo spazio post-sovietico visto attraverso la lente del patrimonio
religioso. Indaga uno degli aspetti che più caratterizza l’attualità, in quanto di grande rottura rispetto al
periodo precedente, quando gli Stati oggi indipendenti erano parte dell’Unione Sovietica dove veniva
promosso l’ateismo di Stato. Si affronta la trasformazione dello spazio sacro post-sovietico sotto molteplici
aspetti analizzando lo stato di conservazione del patrimonio religioso, la ricostruzione di luoghi di culto
demoliti in epoca sovietica nonché la massiccia realizzazione di nuovi edifici religiosi. Questi interventi
contemporanei danno una propria interpretazione dell’antichità, della tradizione, del patrimonio da
tramandare e aiutano a comprendere le tante metamorfosi di questo spazio così strategico negli equilibri
globali
Le acque nel contesto nemorense. Spunti per una ricerca
No full textDespite the considerable amount of studies and research on ancient and post-ancient times dedicated to the Nemorense context, there is currently a lack of research aimed at investigating the characterisation and role of water in the dynamics underlying the development of settlements and human presence in ancient times around the ‘mirror of Diana’. Based on the importance of the lake and its springs since protohistoric times and then from the 6th century BC to the 5th century AD, this contribution aims to offer some reflections on the census and use of spring sources and lake waters, which in some cases are closely connected to archaeological remains and infrastructure for management and use in public and private buildings. The analysis will offer the possibility to glimpse the role of water in the development of mythical events and in the performance of cults in and around the lake, or rather to foreshadow the persistence of the water element in religiosity between Antiquity and the Middle Ages
