Constant detection and monitoring of archaeological sites has always been an important national goal for many countries, which recognize fundamental the prior identification of archaeological ...evidence buried for the preservation of heritage. Since the first applications, archaeologists have grasped the potential of using drones to automate data collection of exposed archaeological evidences. But now the technological evolutio allowed to see archaeological buried structures below the ground surface. Until recently, real great obstacle is envisioned by high cost and technical barriers represented by large-scale data implementation and collection. The recent advances in thermal imaging, depth imaging, drones and artificial intelligence technology have reduced costs and improved the quality and volume of data collected and processed. This article proposes a case study where different sensors were combined for the archaeological evaluation of a large area.
La rappresentazione e la comunicazione dell’architettura contemporanea stanno attraversando un momento di cambio di paradigma in cui la presenza e l’uso della fotografia stanno diventando sempre più ...prominenti sia quando si tratti di immagini dell’edificio reale, sia quando l’immagine sia sinteticamente generata da un modello tridimensionale. Già durante il primo movimento moderno si pensava agli edifici visti dall’alto, a volo di biplano, ed ancora prima la prospettiva a volo d’uccello mostrava come in alcune occasioni lo sforzo compositivo venisse concentrato su una parte dell’edificio che non avrebbe mai potuto essere vista direttamente, ma solo percepita attraverso la sua rappresentazione. Ai giorni nostri la fotografia aerea prende sempre maggiore importanza sia nella comunicazione che nella ideazione del progetto architettonico grazie all’esistenza di applicazioni satellitari, che mediano la nostra percezione di essa al punto che è possibile sostenere che la copertura si sia trasformata nella quinta facciata dell’edificio e che questa sia, a volte, quella più importante. In questo contributo presentiamo una riflessione sull’importanza che, nella narrativa fotografica dell’architettura, ha acquisito il punto di vista dall’alto. Proponendo un’analisi delle diverse circostanze che l’hanno propiziata come: la fruizione digitale dell’architettura, l’uso massiccio di sistemi che privilegiano la visione aerea della città e infine l’ampliamento delle possibilità di fotografia aerea tramite droni e altri dispositivi.
We present an approach in which, by exploiting the collaboration of an aerial drone and our autonomous amphibious Rover, data layers containing information detectable only from the ground can be ...added to the aerial maps detected by an aerial drone. In this context, the Rover could be used as a carrier of sensors of different nature (georadar, electronic noses, multispectral cameras, etc ...) which could record information on the ground and link them to aerial images. The rover, having amphibious capabilities, could also be used for surveys in wetlands, rivers, lakes and in the open sea. Anyone who develops sensing technologies and sensors could use this platform as a remotecontrolled carrier to collect and map information of amphibious or unsafe (chemical, biological, termal, nuclear, even social ...) areas. We call it the Horizontal/Vertical data integration.
The challenge of measuring with constant accuracy, a changing and constantly evolving natural scenario, such as a sand mine can be. Quarzwerke Group, the company that owns the quarry, however, has ...clear ideas in this regard: rely on a partner, not only serious and reliable, but also technologically advanced, who immediately sees in drone photogrammetry the fastest, most effective, but above all high precision, and with the support of TPI, Topcon's Polish dealer for more than 30 years, the new inspection techniques of the sand mine, famous for the quality of the supplied product, have guaranteed the mutual satisfaction of client and contractor.
The Faroe Islands are a series of islands 300 kilometers North-West of Scotland. The Faroes are part of Denmark and work with the Danish authorities. They have a subpolar climate, and a population of ...52,000 people. As the islands are developed and change with new buildings and agriculture, the authorities need up-to-date maps of the islands. The Umhví¸rvisstovan use Pix4Dmatic for large scale mapping on of the land to maintain recent records. They gathered over 2,000 images to survey 2.3 square kilometers. It was a successful surveying project with an open-access orthomosaic as an output.
This paper examines the use of digital photogrammetry and terrain data management within GIS applied to Archaeology, i.e. the study and reconstruction of the settlement layout of UÅŸaklı Höyük ...(Central Anatolia, Turkey) during the Hittite period, through 3D surveys and geo-spatial analyses. Thanks to the data acquisition and processing using algorithms software, i.e. Structure for Motion and Multi-view stereo, it was possible to create highresolution photogrammetric products and cartographic maps valuable for interpreting and further examining archaeological evidence collected during excavations. These products include: i) Digital Elevation Models (DEM), ii) 3D textured models, iii) aerial photogrammetric survey of the Hittite temple (Building II) at a scale of 1:200 and, iv) the orthophoto map of the höyük at a scale of 1:500.
Unmanned Aircraft Systemsdelivers a much needed introduction to UAV System technology, taking an integrated approach that avoids compartmentalising the subject. Arranged in four sections, parts 1-3 ...examine the way in which various engineering disciplines affect the design, development and deployment of UAS. The fourth section assesses the future challenges and opportunities of UAS.Technological innovation and increasingly diverse applications are two key drivers of the rapid expansion of UAS technology. The global defence budget for UAS procurement is expanding, and in the future the market for civilian UAVs is expected to outmatch that of the military. Agriculture, meteorology, conservation and border control are just a few of the diverse areas in which UAVs are making a significant impact; the author addresses all of these applications, looking at the roles and technology behind both fixed wing and rotorcraft UAVs.Leading aeronautical consultant Reg Austin co-founded the Bristol International Remotely Piloted Vehicle (RPV) conferences in 1979, which are now the longest-established UAS conferences worldwide. In addition, Austin has over 40 years' experience in the design and development of UAS. One of Austin's programmes, the 'Sprite UAV System' has been deployed around the world and operated by day and night, in all weathers.
