The aim of this paper is to remark possibilities use WorldView-2 imagery for coastline extraction. Applications are conducted on a Phlegrean area in the Campania Region (Italy): considered range particularly interesting because it shows two typologies shoreline including reefs interspersed with segments sandy beach. Two indices used: Normalized Difference Vegetation Index (NDVI) and Water (NDWI).To enhance geometric resolution results pan-sharpening applied so as obtain maps same pixel...
Greenhouse detection and mapping via remote sensing is a complex task, which has already been addressed in numerous studies. In this research, the innovative goal relies on identification of greenhouse horticultural crops that were growing under plastic coverings 30 September 2013. To end, object-based image analysis (OBIA) decision tree classifier (DT) applied to set consisting eight Landsat 8 OLI images collected from May November Moreover, single WorldView-2 satellite acquired 2013, was...
The use of remote-sensing images is becoming common practice in the fight against environmental crimes. However, challenge exploiting complementary information provided by radar and optical data, more conventional sources encoded geographic systems, still open. In this work, we propose a new workflow for detection potentially hazardous cattle-breeding facilities, both synthetic aperture multitemporal data together with geospatial analyses system environment. fusion performed at feature-based...
The coastal environment is a natural and economic resource of extraordinary value, but it constantly modifying susceptible to climate change, human activities hazards. Remote sensing techniques have proved be excellent for area monitoring, the main issue detect borderline between water bodies (ocean, sea, lake or river) land. This research aims define rapid accurate methodological approach, based on k-means algorithm, classify remotely sensed images in an unsupervised way distinguish body...
In this paper we propose a GIS-based methodology, using optical and SAR remote sensing data, together with more conventional sources, for the detection of small cattle breeding areas, potentially responsible hazardous littering. This specific environmental problem is very relevant Caserta area, in southern Italy, where many buffalo farms exist which are not even known to productive activity register, easily monitored surveyed. Experiments on test available ground truth, prove that proposed...
In the last decades, combinations of natural and humanfactors have resulted in extensive morphological changes to our coastlines andin many cases amplified erosion. order limit these theirimpact on coastal zone, it is important toplan specific actions; for this purpose detailed cognizance zone isnecessary. Different heterogeneous data such as historical recent maps,remotely sensed images topographic survey result very useful reconstructtemporal shoreline changes. study attention focalized...
Pan-sharpening methods allow the transfer of higher resolution panchromatic images to multispectral ones concerning same scene. Different approaches are available in literature, and only a part these is included remote sensing software for automatic application. In addition, quality results supplied by specific method varies according characteristics scene; consequence, different algorithms must be compared find best performing one. Nevertheless, pan-sharpening can applied using GIS basic...
Abstract. The latest breed of very high resolution (VHR) commercial satellites opens new possibilities for cartographic and remote sensing applications. In this way, object based image analysis (OBIA) approach has been proved as the best option when working with VHR satellite imagery. OBIA considers spectral, geometric, textural topological attributes associated meaningful objects. Thus, first step OBIA, referred to segmentation, is delineate objects interest. Determination an optimal...
Transmitting sound waves into water, and measuring time interval between emission return of a pulse, single beam echo sounder determines the depth sea. To obtain bathymetric model representing sea-floor continuously, interpolation is necessary to process irregular spaced measured points resulting from acquisition calculate depths in unsampled areas. Several methods are available literature choice most suitable them cannot be made priori, but requires evaluated each time. This paper aims...
Coastal and Marine Geographic Information Systems (CMGISs) permit to collect, manage, analyze a great amount of heterogeneous data concerning coastal, sea, ocean environments, e.g., nautical charts, topographic maps, remotely sensed images. To integrate those layers in CMGIS, particular attention is necessary ensure the perfect geo-localization data, which basic requirement for correct spatial analysis. In fact, above-mentioned types information sources are usually available different...
The integration of thematic layers and DTM (Digital Terrain Model) becomes possible to achieve 3D models that can contextually display the variability both morphology territorial / or environmental components. WorldView-2 high resolution images, presenting a reduced size pixels on ground (0.5 m in panchromatic 2 multispectral) spectral (with 8 bands portion electromagnetic spectrum between wavelengths 400 nm 1040 nm) allow creation very detailed maps land cover. simultaneous availability...
The construction of three-dimensional models the seabed starting from sample data requires use interpolators to calculate depth where it has not been measured. accuracy model depends on several factors, e.g., interpolation method, morphology, density and distribution samples. This article aims investigate bathymetric in relation methods number points available. Eight different available ArcGIS software are analyzed this study, including 6 deterministic methods, i.e., Inverse distance...
GeoEye-1 panchromatic images (geometric resolution: 0.5 m) can be rectified using Rational Polynomial Functions (RPFs) without knowledge of the full sensor information: rectification is conducted DEM (Digital Elevation Model) area as well Ground Control Points (GCPs) which both elevation and X,Y position must known.Check (CPs) with same characteristics GCPs (but not coincident them) are used to verify accuracy product.For CPs coordinates only obtained survey, but also derived from detailed...
<p class="Abstract">Electronic Navigational Charts (ENCs), official databases created by a national hydrographic office and included in Electronic Chart Display Information System (ECDIS), supply, among essential indications for safe navigation, data about sea-bottom morphology terms of depth points isolines. Those are very useful to build bathymetric 3D models: applying interpolation methods, it is possible produce continuous representation the seafloor supporting studies concerning...
