The goal of this paper is the construction of computerized 3D visualization of geological structures. Several Python applications have been used to adapt the paper map-based geological classical information to numerical geological maps represented in HTML files. The models include a map with the stratigraphic and structural contacts and symbols, five serial vertical sections, and a geological block diagram, all with real topography. This block diagram made with 2D figures allows a 3D visualization. Palomeque area (Murcia region, southeastern Spain) has been used as a key-case. This area consists of a deformed Upper Cretaceous to Oligocene succession belonging to the Internal Zone Malaguide Complex. The main structure consists of two thrust-fold sheets forming an imbricate system, also affected by a set of strike-slip faults with a sinistral regime. The constructed maps show a good agreement with the published classical geological maps and cross-sections demonstrating the benefits of using these Python applications. [ABSTRACT FROM AUTHOR]

In this paper, we present a map of the current state of vegetation and land use in a UTM square measuring 10 × 10 km in Utande (La Alcarria, Central Spain) at a semi-detailed scale of 1:20,000. The map presented here offers an example of how to carry out a series of maps of the plant landscape, using regular grid squares of 100 km² (hectads). The map was drawn up using a cartographic method scaled in levels, which can be updated in line with advances in territorial tracking, and enabled us to group together synthetic categories adapted to the biogeographical idiosyncrasy of territory. We recommend combining this phytocoenotic study with another focusing on the flora and the chorology in the same space. A map was obtained with 35 categories, which offers a large-scale image of the biophysical land covers. This will be useful for territorial planning and biodiversity protection.

This paper presents a naïve map that attempts to reflect the vision that Philip II and his advisors probably had of the Spanish road network in the second half of the sixteenth century, a crucial aspect for the choice of the seat of the capital of the kingdom. The elaboration of the naïve map was carried out in two phases: in the first, the road network was reconstructed based on a thorough revision of the primary sources that have survived to the present day. As these sources showed evident problems of completeness, the network was completed using mathematical methods, which were statistically contrasted. The analysis carried out is an important novelty since it shows that most of the transport in the Iberian Peninsula was channeled through the center following a radial structure with six principal axes two centuries before what has been traditionally considered.

During the last 3 ka, different human communities occupied the Bay of Cádiz (SW Spain), including Phoenician, Carthaginian, Roman, Medieval and Modern settlements. Traces of such historical occupations have been recognized along the bay from a geoarchaeological point of view. Some of them bear a palaeogeographical interest related to the historical location of the shoreline. At the same time, Holocene sedimentary units and geomorphological elements identified along the bay can be interpreted as evidences of its morphological evolution. The objective of the present paper is to represent all the available data about archaeological sites and geomorphology in the northern Bay of Cádiz, with the aim of combining both sources of data for elaborating a simple proposal of landscape evolution during the last 3 millennia. The base for mapping was multiple, from historical aerial photographs to satellite imagery and a digital terrain model with a maximum resolution of 0.35 m. [ABSTRACT FROM AUTHOR]

The dynamics of anthropic occupation of a territory over time play a central role in shaping the cultural landscape we see today. This paper presents a methodology for visually representing this phenomenon. The method consists of transforming data from archaeological records and historic cartography into a series of maps that allow historic settlement patterns to be interpreted and the historic depth of contemporary urban areas to be revealed. To create these maps, a series of geospatial analyses were carried out, including density analysis and weighted overlay. The methodology was applied to the peri-urban area of Seville in southern Spain, although it may be extrapolated to other regions. [ABSTRACT FROM AUTHOR]

This paper presents a geomorphological analysis of the littoral zone of the Arosa-Pontevedra estuary mouth and identifies geomorphological units and categorizes them into morphogenetic systems. The different morphogenetic systems are used to establish a comprehensive evolutionary analysis, contrasting the depositional systems found in the continental littoral zone with the marine erosional systems (‘rasas’). The compiled cartography groups the geomorphological units into the following: the lithoestructural morphogenetic system with large-scale forms (domes, inselbergs, residual relief, etc.) and small-scale forms (gnammas, tafoni, channels, etc.); the littoral morphogenetic system comprised of marine (marine terraces, beaches, tidal bars, tombolos and coastal arrows), transition (marshes, lagoons and fan deltas) and eolian (dune systems) settings; the fluvial morphogenetic system with channelled (alluvial, flood plain and river terraces), transition (alluvial fans and alluvial cones) and sheet flood (pediments and glacis) systems; the gravitational morphogenetic system (colluvium); and the alteration morphogenetic system (sand-alteration).

In this paper, we report on a compilation of more than 2200 sites (more than 10,000 individual measurements) where anisotropy of magnetic susceptibility (AMS) was studied in granites from the Variscan Pyrenees. The standardization and homogenization of this information has allowed us to produce threeMain Mapsthat synthesize all the information related with the AMS of the Pyrenean granites. We also describe the problems found during the construction of the database (variable geo-positioning, different published information, etc.). The information derived from 21 granite bodies, the database, and the synthesis maps (magnetic susceptibility, Km, and the orientation of the magnetic foliation, plane perpendicular to k3, and of the magnetic lineation, k1) allow us to see for the first time a complete image of this important kinematic and petrographic indicator.

This paper presents a geological map and cross-sections of the Cotiella thrust sheet at 1:25,000 and 1:50,000 scale, respectively. The map covers an area of 225 km2in the southern Pyrenees. The structure of the studied area is dominated by an upper Santonian – lower Miocene thrust system, which transported a middle Coniacian-lower Santonian extensional basin, the Cotiella Basin, 10 s of kilometres southwards during the Pyrenean orogeny. The map focuses on the internal structure of the Cotiella Basin, its partially inverted extensional faults and its up to 6.5 km of upper Albian – lower Santonian sediments that unconformably overlie Upper Triassic salts. The map and cross-sections, together with outcrop-scale observations, have led us to interpret the rising of passive diapirs in the area. This newly recognized salt tectonic event in the Cotiella Basin is important because of the insights it can provide for the paleogeographic reconstruction of the Upper Cretaceous paleomargin of the northern parts of the Iberian Peninsula.
