Digital Mapping and 3D Analysis

The activities of this laboratory are focused on cartography, reconstruction and spatial analysis of geological and archaeological elements. Among its products, the following are particularly noteworthy: geological and geomorphological cartography, paleogeographic reconstructions, analysis of spatial patterns, 3D reconstructions and the morphometric analysis of archaeological sites and objects for different research projects in Europe and Africa. 

These activities, which take place both in the field and inside caves, can cover temporal sequences. Thus, the digitalization, reconstruction and analysis of Natural and Cultural Heritage can also be approached from a 4D perspective

The laboratory has high-precision topographic equipment such as total stations, GPS/GNSS systems, photogrammetry systems, drones and spherical photography, and laser scanners for use in the field and in the laboratory. This equipment is complemented by the necessary hardware and software for data processing and analysis, such as Geographic Information Systems (GIS), teledetection and 3D applications.

The Total Station and GPS/GNSS systems (high-precision topographic machines) are used for detailed geoarchaeological mapping, to document the characteristics of archaeological and paleontological sites, to archive findings, to position samples and to conduct topographic surveys in order to generate a quality data infrastructure for the study, interpretation, conservation, dissemination and cultural development of sites.

The 3D Laser field Scanner with LIDAR technology and photographic texture capture is a device that can discreetly capture any element in three dimensions (3D) at very high resolution, so that it can be digitally analyzed in a CAD, SIG or BD environment. The product generated is an actual size high-density point cloud, based on which we can make metric calculations, obtain sketches, cuts and sections, vectorize entities and model the desired elements in 2D/3D. The information obtained can be used to build three-dimensional digital models using a wide range of applications, such as archeology and geological, geomorphological and stratigraphic cartography.

The 3D handheld Laser Scanner is a device that analyzes an object or scene to gather data on its shape and occasionally on its color. The information obtained also includes 3D meshes and high-density point clouds whose application enables both the visual and digital dissemination of the objects analyzed and their 3D metric analysis.

The drones or unmanned air vehicles (UAV) are booming technologies with wide application for taking aerial photographs and videos in order to document specific locations and their surroundings, and for different types of base cartography, such as topographies, 3D surveys and orthophotographies. These products are employed for the dissemination of the elements analyzed and for different types of thematic mapping, such as site planimetry, geomorphological maps, geological maps and stylographic surveys.

Photogrammetry is a technique used to determine the geometric properties of objects and spatial situations based on photographic images. Generally, the purpose of this technique is to create a point cloud to extrapolate the shape of the object. The product generated is an actual size high-density triangulation mesh, based on which we can make metric calculations, obtain sketches, cuts and sections, vectorize entities and model elements.
