Remote sensing allowed monitoring the reservoir water level by estimating its surface extension. Surface extension has been estimated using different approaches, employing both optical (Landsat 5 TM, Landsat 7 ETM+ SLC-Off, 8 OLI-TIRS and ASTER images) Synthetic Aperture Radar (SAR) images (Cosmo SkyMed TerraSAR-X). Images were characterized acquisition modes, geometric spectral resolutions, allowing evaluation of alternative and/or complementary techniques. For each kind image, two...
The identification of wetland vegetation is essential for environmental protection and management as well monitoring wetlands’ health assessing ecosystem services. However, some limitations on classification may be related to remote sensing technology, confusion between plant species, challenges inadequate data accuracy. In this paper, in the Yancheng Coastal Wetlands studied evaluated from Sentinel-2 images based a random forest algorithm. Based consistent time series observations,...
Changes in the seafloor relief are particularly noticeable shallow waterbodies (at depths up to several metres), where they of significance for human safety and environmental protection, as well which highest measurement accuracy is required.

As part model, three technology components will be created: a hydroacoustic optoelectronic component proposed by...
The spread of new survey strategies for the documentation and 3D reconstruction complex cultural heritage sites enables implementation virtual web navigation systems that are useful their fruition. In particular, remote indoor/outdoor exploration enhances our knowledge sites, even in inaccessible or difficult-to-visit states. However, data acquisition remains a challenge, these datasets is often limited to property software implementations. This work describes construction an visualization...
Worldwide, the determination of coordinates from a Global Navigation Satellite System (GNSS) survey (in Network Real Time Kinematic, Precise Point Positioning, or static mode) has been analysed in several scientific and technical applications. Many those have carried out to compare Positioning (PPP), Kinematic (NRTK), modes’ solutions, usually, using latter as true most plausible solution. This approach is not always possible mode solution depends on parameters (baseline length, acquisition...
Many factors can influence the displacements of a dam, including water level variability and environmental temperatures, in addition to dam composition. In this work, optical-based classification, thermal diachronic analysis, quasi-PS (Persistent Scatter) Interferometric SAR technique have been applied determine both forcing resulting crest Castello (South Italy) over one-year time period. The dataset includes Sentinel-1A images acquired Wide swath mode using Terrain Observation with...
In this work, the performance of multi-GNSS (Global Navigation Satellite System) Precise Point Positioning (PPP) technique, in static mode, is analyzed. Specifically, GPS System), GLONASS, and Galileo systems are considered, quantifying contribution one main objectives.

This paper shows the results of a scientific research in which GNSS continuous monitoring system for earth-dam deformations has been developed, then, have related with reservoir water surface and level. The experiment was conducted near Bivona (Sicily, Italy), on Castello dam (Magazzolo Lake). On top three control points were placed permanent stations installed. continuously transmitted data to centre University Palermo. former determined using freely available satellite (specifically...
This work gives a comparison between different mathematicalmodels for the evaluation of movements an earthendam situated Bivona and Alessandria della Rocca, inthe province Agrigento (AG), Italy. The models selected areof hydraulic nature, already tested on concrete dams, andfinite elements which, contrary, exploit geotechnicalparameters. results obtained from comparisonof displacement planimetric components relativetime series data over period two years appear to befully satisfactory, in...

The continuous availability and rapid accessibility to multispectral data from satellite platforms within the Copernicus Programme represents a great opportunity for users in different fields of applications as: agriculture, observation coastal zones, monitoring land cover change.The aim this paper is identify suitable method map coastline using Sentinel-2 optical image.The provides use two indexes developed remote sensing field water environment: NDWI (Normalized difference index) MNDWI...
Estimating the accurate position of shoreline over time can be challenging. We propose a new approach to delimit from remotely sensed images simply and accurately. This treats pixels as simultaneous radiometric measurements and, by examining distance between iso-radiometry lines, assumes in where behavior changes more suddenly. The analyses conducted applying this coastline extraction underscore its significant flexibility. Specifically, yields promising outcomes even if applied variety...

Shoreline variations, triggered by climate change, eustatism, and tectonic, drive the coastal landscape evolution over multiple spatial temporal scales. Among many different existing coast types, sandy coasts are most sensitive to erosion accretion processes and, at same time, often host valuable anthropogenic assets. The rapid ongoing of these environments poses challenges for their management, necessitating cost-effective highly reliable methods measuring changes. Many remotely sensed...
