Introducción a la fotogrametria – Daniel Deagostini Routin – Google Books

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. Movimientos en masa naturales o inducidos: 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. 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.

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. The proposed approach is a cost-effective, robust and rapid method for image processing in remote areas were no traditional surveying technologies are available.

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.

However, beyond the scientific and technical information provided by the data, the 3D documentation of ancient mining scenarios is a powerful tool for an effective and wider public diffusion ensuring the visualization, preservation and awareness over the importance and conservation of world mining heritage sites.

It is characterized by the presence of remnants of glacial landforms, active during most of the Upper 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.

Along the northern slope the glacial features are well developed, showing multiple cirques and moraine arcs. 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.

Moraines have been intensively gotointerpretacion 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 fotogramegria of water needed for the roman works.

Thus, hiding the effect of natural processes on the landscape and the identification and preservation of glacial landforms.

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. Based on the scanning of the Earth’s surface, LiDAR technology allows the compilation of high resolution digital terrain models. This technique has been widely used in recent years in archeological works to characterize heritage features and ancient human-made structures and buildings.

It is particularly effective in areas with dense vegetation or difficult to access, where traditional surveying is intricated. Unlike other traditional methods in archeology, LiDAR enables to control parameters such as height and angle of light incidence, enhancing data visualization and aiming for the interpretation of obtained information.

In this work we presented a detailed mapping that integrates LiDAR and aerial photography for the identification of Roman mining works in northwest Spain. The presence of significant gold deposits led to an intensive extractive labor during the first century bC. Gold mineralization in this area is associated with quartz veins and dykes in Paleozoic rocks primary and Miocene and Gold mineralization in this area is associated with quartz veins and dykes in Paleozoic rocks primary and Miocene and Quaternary sediments secondary.

Hitherto, ancient prospection works in Miocene materials were focused on the location of alluvial fan deposits according to the Roman literary descriptions.

However, the finding of mining areas and remains of hydraulic structures located in reddish-orange hillside deposits suggests that there may have had other prospective indicators. We present a mineralogical study of optical microscopy and X-Ray diffraction for the provenance analysis of iron oxides studied in pebbles within these sediments and ironstone deposits located next to the main mining areas.

The formation fotointrepretacion secondary goethite, probably related to the recent chemical weathering of chlorites formed during Variscan metamorphismcould be the responsible for the intense reddish coating. This could have served to Roman miners as gold signs, beyond other indications such as texture and roundness of rockpebbles in sediments.

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. Besides that, the main advantages over other traditional methodologies used in archaeological exploration such as photo-grammetry, highlights the rapid collection of data as a point cloud, simplifying the processing and conversion into a digital model by Geographic Information Systems software platforms; the control of displaying parameters is facilitated and data analysis is improved, simplifying the characterization and interpretation fotointefpretacion the obtained information.

In this work we present a mapping based on the application of airborne LiDAR fotogrametira identify the Roman mining works carried out in northwest Spain.

So far, our results shed light into the distribution and complexity of the mining hydraulic system fotointerpretcaion location of unknown gold deposits, highlighting the potential of LiDAR for the identification of ancient mining heritage in highly vegetated areas. LiDAR technology, based on Earth’s surface scanning, allows the compilation of high resolution digital terrain models.

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. 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.

The presence of gold deposits led to intensive extractive work during the first century b. 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.

Improving fotointerpretadion prospection using localized UAVs assisted photogrammetry: This paper reports the use of integrated geomatic applications based on LiDAR data and UAV assisted photogram-metry for the identification, description and interpretation of ancient Roman gold mining sites in Northwest Spain. The study compares Digital Elevation Models DEMs with different acquisition methods, resolution and accuracy for analysis of archaeological remains.

DEMs have been analysed using different visualization tools, such as principal component analysis, local relief factor, multiple hillshading, sky-view-factor and openness in order to improve visualization of the models, aiming at the identification of archaeological features. Our study suggests that principal component analysis, openness and votogrametria hillshading were the most effective tools for identification of archaeological remains.

The results indicate that 5 m LiDAR provides insufficient resolution to gotogrametria detailed analysis and accurate description of the hydraulic systems, but the use of visualization tools improved the localization and dotogrametria of remains. The 1 m resolution LiDAR data highly improve the resolution and capabilities for recognition and interpretation of canals, water reservoirs and mining zones.

In additionthe use of UAV technology for smaller detailed surveys has shown a powerful capacity to reduce costs and time-consuming processing calculations, gaining in data resolution.

Fotkgrametria files allows classification and analysis of point clouds yielding similar results to LiDAR technology in vegetated areas. However, unlike airborne lasers, its application is mainly restricted to small survey areas.

Our study has focused on two areas characterized by a diversity of roman gold mining elements fotointwrpretacion in the landscape, such as hydraulic systems canals and water reservoirs, drained canals and other anthropic elements and mining areas along the Eria River Valley Gold District.

The work has been implemented with the creation of 3D virtual reconstructions of the selected features, which can help to visualize different elements of the archaeological record to the general public, providing fotointerprtacion useful tool for preservation and display of cultural heritage.
