UAV technology provides a non-invasive procedure valuable for the acquisition of digital information in remote, difficult to access areas or under the risk of destruction. Download as pptx, pdf, txt or read online from scribd. The results indicate that 5 m LiDAR provides insufficient resolution to perform detailed analysis and fotohrametria description of the hydraulic systems, but the use of visualization tools improved the localization and description of remains.

Forest monitoring, temperate forest, forest canopy density, high-resolution, small-format imagery, multitemporal assessment, aerial photographic series. Gold mineralization in this area is associated with quartz veins and dykes in Paleozoic rocks primary and Miocene and Presentaciones fotogrametria y fotointerpretacion inicio.
During the last decade, the application for identification of heritage elements and other ancient remains in archaeology has extensively contributed to study areas difficult to access or covered by a dense vegetation, where archeological surveys become complicated.
It is particularly effective in areas with dense vegetation or difficult to access, where traditional surveying is intricated. Along the northern slope the glacial features are well developed, showing multiple cirques and moraine arcs.
Clarifying that at any time they need data for nonprofit purposes, through formal request they will be able to offer the raw data. Sincethis method has been used to determine appropriate payment for environmental services.
We present the preliminary results of the mapping of glacial remains based on the integration of natural and human-induced transformations occurred in historical period. In this work we present a mapping based on the application of airborne LiDAR to identify the Roman mining works carried out in northwest Spain. Hitherto, ancient prospection works in Miocene materials were focused on the location of alluvial fan deposits according to the Roman literary descriptions.
Movimientos en masa naturales o inducidos: However, geomorphological remains are not well preserved in the southern flank where a few evidences of glacial and fluvioglacial activity, represented by remains of moraine deposits and terraces, are partially transformed.
In this study we present an integrated LiDAR and aerial photography data analysis in order to obtain a detailed map of ancient mining works within a small sector of the Roman mining district in northwestern Spain. This technique has been widely used in recent years in archeological works to characterize heritage features and ancient human-made structures and buildings.
Help Center Find new research papers in: Recently used in archaeological works for the discovery and description of heritage features such as ancient human-made This could have served to Roman miners as gold signs, beyond other indications such as texture and roundness of rockpebbles in sediments. The 1 m resolution LiDAR data highly improve the resolution and capabilities for recognition and interpretation of canals, water reservoirs and mining zones. A multiannual series of high-resolution smallformat aerial digital photography was employed to assess changes in the forest canopy density in a temperate forest.
Remember me on this computer. This contribution discusses the potential of UAV-assisted unmanned aerial vehicles photogrammetry for the study and preservation of mining heritage sites using the example of Roman gold mining infrastructure in northwestern Spain.
Improving archaeological prospection using localized UAVs assisted photogrammetry: This payment together with an intense interaction with the communities has led to a reduction in forest degradation and deforestation in the core zone.
LAZ files allows classification and analysis of point clouds yielding similar results to LiDAR technology in vegetated areas. LiDAR technology, based on Earth’s surface scanning, allows the compilation of high resolution digital terrain models.
It is characterized by the presence of remnants of glacial landforms, active during most of the Upper Pleistocene, and represented by several cirques and related deposits. On the basis that users level 1 could be students, teachers and the general public, and they can access only to layers in image format and to documents and reports in txt or pdf etc.

The study compares Digital Elevation Models DEMs with different acquisition methods, resolution and accuracy for analysis of archaeological remains.
Skip to main content. Since the second half of the twentieth century, the undertaking of a number of hydraulic and hydroelectric projects has contributed to the disruption of the balance of water and sediment flows in river basins, leading to accelerated processes of progradation and regression in deltaic and other coastal landforms.
Moraines have been intensively affected by goldmining works carried out during the Roman times, comprising the presence of a complex hydraulic system with canals and water reservoirs used for the transport and storage of water needed for the roman works. The results provide high-resolution orthomosaic, DEMs and 3D textured models that aim for the documentation of ancient mining scenarios, providing high-resolution digital information that improves the identification, description and interpretation of mining elements such as the hydraulic infrastructure, the presence of open-cast mines which exemplifies the different exploitation methods, and settlements.
Su actividad investigadora ha sido premiada con numerosas becas y premios de reconocido prestigio europeo, siendo sus trabajos publicados en revistas de alto impacto internacional. Among its main advantages over other traditional methods of archaeological research, it highlights the possibility of controlling display parameters, which in turn facilitates data analysis and interpretation.

The study area represents the largest gold area in Roman times and comprises 7 mining elements of interest that characterize the most representative examples of such ancient works. A combination of conventional and adapted techniques of photogrammetry and photo interpretation was used, establishing a specific method. In additionthe use fotointeerpretacion UAV technology for smaller detailed surveys has shown a powerful capacity to reduce costs and time-consuming processing calculations, gaining in data resolution.

This work highlights the scope of the ancient mining works and their impact on the landscape, which are much greater and more important than previously thought.
