In the first part of the essay, the author states that the "abyssal" cartographical lines that used to demarcate the Old and the New World during colonial times are still alive in the structure of modern occidental thought and remain constitutive of the political and cultural relations held by the contemporary world system. Global social iniquity would thus be strictly related to global cognitive iniquity, in such a way that the struggle for a global social justice requires the construction of a "post-abyssal" thought.

There are numerous maps of the spontaneous vegetation of Argentina. However, a country-level map with enough detail to discriminate vegetation units within the phytogeographic provinces described by Cabrera (1976) is lacking. We analyzed vegetation descriptions published in recent decades, with special attention to those that produced physiognomic-floristic maps. As a result of this analysis, here we present a physiognomic-floristic map of spontaneous vegetation of Argentina that shows the heterogeneity within phytogeographic provinces. The map has 50 vegetation units as subdivisions of the phytogeographic ecotone and provinces early described, and a brief physiognomic-floristic description of each ecotone, province and vegetation unit. We propose a nomenclature of each vegetation unit based on dominant type of spontaneous vegetation and characteristic species and present digital cartographic material.https://doi.org/10.25260/EA.18.28.1.0.399

The NASA Ames Stereo Pipeline is a suite of free and open source automated geodesy and stereogrammetry tools designed for processing stereo images captured from satellites (around Earth and other planets), robotic rovers, aerial cameras, and historical images, with and without accurate camera pose information. It produces cartographic products, including digital terrain models, ortho‐projected images, 3‐D models, and bundle‐adjusted networks of cameras. Ames Stereo Pipeline's data products are suitable for science analysis, mission planning, and public outreach.

This issue of the Bibliography includes items published from 2015 to 2018. The form of entries reflects the order and punctuation conventions of ISBD (M) : International Standard Bibliographic Description for Monographic Publications, rev. ed. (s.l. : International Federation of Library Associations and Institutions, 2002. — http://www.ifla.org/VII/s13/pubs/isbd_m0602.pdf), but with modifications to accommodate articles in journals and collective works. Some English translations or paraphrases of titles have been supplied. The abbreviation ‘ill.’ alone implies illustration(s) of a cartographic nature; where both ‘ill.’ and ‘maps’ occur together illustrations of a general and of a cartographic nature are included.

Raymond Craib

This vivid social history reveals the powerful role that cartographic projects such as exploration, surveying, and mapping played in the creation of modern Mexico in the late nineteenth and early twentieth centuries. Raymond B. Craib describes the varied and pervasive attempts by government officials to determine the lines and claims that would define the nation. These projects included the privatization of communal lands; the delineation and archiving of village, municipal, state, and national boundaries; and the determination of waterways and water rights. As Craib emphasizes, the everyday processes of these cartographic routines proved to be much more conflicted than is indicated by their end products: maps with unitary and smooth facades. Taking central Veracruz as a case in point, Craib shows how agrarian officials, military surveyors, and metropolitan geographers traversed "fugitive landscapes" of overlapping jurisdictions and use-rights, opaque tenure systems, confusing property regimes, ambiguous borders, and shifting place names. He draws on an array of sources--including maps, letters from campesinos, official reports, and surveyors' journals and correspondence--to trace the everyday, contested processes through which officials attempted to redefine and codify these landscapes in struggle with the villagers they encountered in the field. In the process, he demonstrates in meticulous detail how surveying and mapping were never mere technical procedures: they were--and remain to this day--profoundly social and political processes in which rural people, long ignored in the history of cartography, were actively involved.

The construction of large-aperture radio telescopes, such as the Five-hundred-meter Aperture Spherical radio Telescope (FAST), demands careful site selection to balance performance, cost-efficiency, and electromagnetic shielding. Natural karst depressions are often ideal candidates; however, conventional algorithms, particularly the fill-sink approach, struggle to identify single-sided open depressions, which feature partially open boundaries typically less than [Formula: see text] in width. This study proposes a general method for identifying both enclosed and single-sided open depressions using digital elevation models (DEMs). The method integrates customized template matching, cut-and-fill volume evaluation, and positional weight adjustments to prioritize terrain requiring minimal earthwork while maintaining radio shielding. A case study in Qingyuan, Guangdong, China, identified 32 candidate depressions, including 17 enclosed and 15 single-sided open types. Compared with the fill-sink algorithm (precision = 80.0%, recall = 53.3%), the proposed method achieves significantly higher accuracy (precision = 94.1%, recall = 96.9%). This method offers a robust and adaptable solution for large-scale telescope site selection in complex terrains. Moreover, identifying additional suitable depressions provides strategic opportunities to construct multiple FAST-like telescopes within an appropriate distance, enabling interferometric observations that could greatly enhance detection capabilities.

Maritime shipping is a cornerstone of South Korea’s economy, yet emissions from port operations remain a major contributor to urban air pollution. However, few studies have quantitatively isolated the specific contribution of ship traffic to local PM2.5 levels within port-city environments, especially at fine spatial scales. The current study examines the dispersion of PM2.5 around Busan Port, with a focus on buffer zones of 3 and 10 km from the emission control area (ECA) boundary. We integrate high-resolution automatic identification system (AIS) vessel movement data with ground-based air quality measurements and meteorological observations to capture both emission sources and atmospheric transport dynamics. Two advanced gradient boosting models, LightGBM and XGBoost, were developed and evaluated using K-fold cross-validation; LightGBM achieved strong predictive performance (R² = 0.882), demonstrating the value of data-driven modeling for port air-quality assessment. The results indicate that ship-derived PM2.5 emissions are the main predictor in the 3-km zone, while wind speed is the most critical factor driving dispersion in both zones. SHAP and PDP analyses provide a transparent interpretation, confirming the relative influence of ship emissions versus meteorological controls. The novelty of this work lies in the spatially explicit integration of AIS-based emissions with meteorological variables within multiple buffer zones.
