Science in the service of politics. The cartographic representation of a local territorial context of the Kingdom of Naples in the early nineteenth century

The erudite priest Marciano Di Leo (1751–1819), a prominent personality in the historical and geographical panorama of his time, not only in his home territory, authored a vast literary and poetic production, but also tried his hand at producing some maps, referring to a province of the Kingdom of Naples. At a time when the principles of geodetic cartography had become increasingly known, even locally, hand in hand with improvements in technology and accuracy of measurements, the author reflects the historical narratives of progress of the European (and Neapolitan) Enlightenment and translates them into an unpublished manuscript of statistical, historical, and geographical nature, accompanied by numerous maps of various scales. The rediscovery of a largely unknown—and therefore not very thorough—minor cartographic production underscores the spread even in more marginal contexts of the most innovative ideas and increasingly precise scientific foundations in the cartographic-mathematical representation of the territory. It also illustrates the role of a number of intellectuals in the service of the political choices of their time, in an attempt-often unrealized-to bring about a decisive change of course in public administration, in accordance with Enlightenment ideals and in the spirit of reform that spread throughout Europe thanks to the French Revolution.

The Urbanism and Geography in Green Regions of Europe

This article refers to Hallstatt in Austria and Ioannina in Greece. The goals analyze the two locations that have similarities in geometric shape, digital elevation model (DEM), and geomorphology. Firstly, Hallsatt’s advances were more technical than aesthetic. There is a general tendency towards extravagance and baroque and Greco-Oriental influences. Secondly, Ioannina is a mountainous city located around Lake Pamvotis. The geometry develops parallel to the lake. The city experiences many cultures. The ancient city had an urban planning that characterized the Ottoman Empire. In the old part, there is the castle, old stone streets, wooden houses, and the house of the Greek Muslim Ali Pasha. The author obtains numerous aerial photographs using Google Earth software. The photographs were received dynamically for all the perimeters of the regions. In short, the cartographer has between 15 and 20 photographs. The next step is to align the photographs in Zephyr photogrammetry software. Configuring resolutions, distance, camera locations, contrast, and brightness is essential. The final products are the 3D texture, 3D model, and orthophotos from Hallstatt and Ioannina. Digital products are suitable for measuring areas, circumferences, and heights. Furthermore, digital products represent a digital archiving practice: conservation and visualization are crucial factors today as they share, represent, promote, and document urban planning, historical memory, and the natural environment.

The outer ring of a circular structure in the Marche Region, Central Italy: Evidence of a non-extraterrestrial origin

Google Earth images in the Marche Region of Central Italy revealed a circular structure consisting of a ring system made up of concentric hills and valleys. Cartography, DEM, geological, and available geophysical data were used to constrain the possible origin of the structure. Located in the Messinian foredeep deposits of the Central Apennines, it has a rim diameter of 3.75 km and a central uplift connected to its southernmost part. As it was formed in the clays of the Lower Pliocene, and clays are believed to have emerged definitively after the Upper Pliocene, its age might be constrained to the Lower Pleistocene. Similar concentric structures are usually found in impact craters, sedimentary domes, and volcanic landforms. As salt domes and magmatic activity are not found in this region, this study seeks to validate the results of previous work that it was the result of an ancient impact crater, of hydrological, brachy anticline, or clayey diapiric origins. Specifically, an observed second ring portion, with a curvature radius about double the first in size, will be investigated in this work. This second ring portion appears to be concentric to the first one and is visible along the its northern and western parts. Although double concentric rings are usually due to impact craters, the absence of the ring portion in the other two directions, and the probable deviation of a river, deduced by studying hydrography, supports the hypothesis that it might be of a clay diapir origin.

The importance of citizen science in coastal monitoring. Learnings from experience in Villa Gesell (Argentina)

Climate change has affected the coasts of the world due to numerous factors, including the change in the intensity and frequencies of the storms and the increase in the mean sea level, among others. Argentina has extensive coastal areas, and research and monitoring tasks are expensive and require a significant number of personnel to cover large geographical areas. Given this, citizen science has become a tool to increase scientific research's spatial and temporal extension. Therefore, the paper aims to analyze the methodology and development of the citizen science project in Villa Gesell and its lessons for applying them in future coastal environmental monitoring projects. The methodology was based on an experience of the project co-created between activists and researchers. This project included four phases for social and physical aspects: training for the citizens, theoretic and practice on coastal dynamics, and how to measure its geomorphological and oceanographic variations; data collection: the activists who received the training performed the measurements to monitor them beach; data analysis by scientists; and dissemination of results, the report data were disseminated by citizens in their community. The analysis of case studies in citizen science projects generates a fundamental learning arena to apply in future projects. Among the positive aspects were the phases established for their development and the methodology used to collect beach monitoring data.
