Abstract:

Remote sensing techniques could enable remarkable advances in characterizing rivers hydromorphology by providing spatially and temporally explicit information. Remote mapping of hydromorphology can play a decisive role in a wide range of river science and management applications including habitat modeling and river restoration. High resolution satellite imagery (HRSI) has recently emerged as potentially powerful means of mapping riverine environments. This research aims to develop advanced methodologies for processing HRSI to map and quantify a set of key hydromorphological attributes includin

Abstract:

Coastal environments are facing constant changes over time due not only to their dynamic nature but also to geological, geomorphological, hydrodynamic, biological, climatic and anthropogenic factors. Nowadays, erosion phenomena exceed those of accretion. For these reasons, the monitoring of these areas is crucial for the safeguarding of the cultural heritage and the populations living there. Knowledge of shoreline dynamics helps to understand and study a wide range of coastal area studies and, in general, its management and planning. The focus of this research is based on the integration betwe

Abstract:

Drought affects more people than any other natural disaster and results in serious economic, social and environmental costs. The development of effective drought monitoring and early warning has been a significant challenge because of the unique characteristics of drought. In fact, considering the multifaceted nature of drought phenomena (i.e. hydrological, meteorological, and agricultural), a comprehensive and integrated approach is required to define effective Early Warning Systems (EWS), which are thus based on the monitoring of different drought-related parameters and complex drought indic

Drought is a natural hazard characterized by a high degree of complexity thus its investigation could be best performed only through a complex analysis involving a set of environmental variables and their intricate relationships.

One of the fundamental drought variables is of course soil moisture, a key parameter determining crop yield potential

Abstract:

In the field of the GNSS (Global Navigation Satellite System) with the NavStar GPS and Glonass systems it is already known and common the RTK real time positioning method. The RTK involves two, or more, GNSS receivers, the first one called Master set up on a landmark, and the second one, or ones, called Rover/s, used for the land surveying of the unkown points. At the beginning, the data link for the transmission of the differential correction from the Master to the Rover/s was made by radio links. Then, twice GSM modems have been used for the radio link, thanks to the spread of the GMS

Abstract:

Access to geographic information has radically changed in the past decade. Previously, it was a specific task, for which complex desktop Geographic Information Systems (GISs) were built, and geographic data was maintained locally, managed by a restricted number of technicians. With the significant impact of the world-wide-web, an increasing number of different geographic services became available from heterogeneous sources. To support interoperability among different providers and users, GIS agencies have started to adopt Spatial Data Infrastructure (SDI) models. Usually, each SDI service pro

Abstract:

Il risultato di più di mezzo secolo di attività di ricerca a livello nazionale e internazionale sulla documentazione dei beni culturali ha prodotto un progressivo allargamento del concetto di bene culturale e dei compiti della tutela. A partire dalle prime formulazioni si è giunti ad una definizione più ampia che tiene conto della complessità del fenomeno e della sua stretta integrazione con il territorio. Quest'evoluzione ha portato anche ad un mutamento delle politiche di tutela e alla nascita del concetto di valorizzazione. Da una visione basata esclusivamente sulla salvaguardia del bene si

Abstract:

The recent years saw a growing usage of remote sensing platforms, such as satellites and unmanned aircraft vehicles (UAVs). The Copernicus observation programme is an example of a new satellite constellation improving and promoting easy free access dataset, timely updated. The high popularity of UAVs is related to the obtaining high-resolution data, quickly at a relatively low cost. As result, sensors with high spatial and temporal resolution produce a great number of data, and these data increase exponentially. Consequently, the software for image processing play a key role in the diffusion o

Abstract:

La frammentazione delle informazioni rappresenta una sfida aperta nel settore AEC, incluso il patrimonio costruito, causando notevoli difficoltà nella gestione delle stesse. Diversi metodi e strumenti sono stati sviluppati per mitigare tale perdita; uno di questi è il BIM. In riferimento al patrimonio costruito, la tesi affronta lo sviluppo della gestione dei dati che saranno strutturati per raggiungere un certo livello di informazione attraverso il BIM. La prima fase della gestione dei dati riguarda l'apporto di tecniche geomatiche che permettono di acquisire ed elaborare dati metrici per ott

Abstract:

The study is inserted in the framework of information extraction from satellite imageries for supporting rapid mapping activities, where information need to be extracted quickly and the elimination, also if partially, of manual digitalization procedures, can be considered a great breakthrough. The main aim of this study was therefore to develop algorithms for the extraction of urban layer by means of medium spatial resolution Landsat data processing; Decision Tree classifier was investigated as classification techniques, thus it allows to extract rules that can be later applied to different

Abstract:

Negli ultimi anni l’uso di Aeromobili a Pilotaggio Remoto (APR), o semplicemente droni, ha interessato molti campi. La loro estrema versatilità li ha resi efficaci strumenti anche nel campo del telerilevamento, grazie alla crescente disponibilità di sensoristica installabile a bordo, da sistemi LiDAR (Light Detection And Ranging) a camere digitali di vario tipo. Tra queste ultime, è aumentato il numero di camere multispettrali a basso costo capaci di acquisire informazioni spettrali nel campo del vicino infrarosso. Grazie all’elevata risoluzione geometrica (centimetrica) che è possibile ragg
