Geomorphological map of the Alta Ribagorza (Central Pyrenees, Spain)

Abstract

The 1:50,000 geomorphological map of the Pyrenean Alta Ribagorza is presented here. The Spanish Alta Ribargoza is located in the northern sector of the provinces of Huesca and Lérida, and includes the highest summit of the Pyrenean mountains (Pico de Aneto, 3404 m a.s.l.). The mapped sector measures approximate 700 km 2 . The basic source of information for the completion of the map was derived from the photointerpretation of two series of aerial photos (the 1981 "Pirineos Sur" flight, scale 1:30,000, black and white; and the 2006 PNOA flight, scale 1:5,000, colour), and field work. The map-legend includes 44 elements classified into six main sections, covering lithology and structure, processes and landforms of glacial, periglacial, nival, hillslope, karstic and fluvial origin, and conventional symbols. The variety of the identified processes and landforms demonstrates the geomorphological richness of this mid-latitude, high-mountain area, and the map constitutes a useful tool for land management.

Elementary forms and “scientific reliability” as an innovative approach to geomorphological mapping

“…Therefore, the origin of each part of the relief could be evaluated equally. On traditional geomorphological maps (Demek et al, 1972), however, only significant landforms are presented (and their genesis is explicitly shown on the map), while remaining parts of the relief are covered by a map of gradient (Demek and Kopecký, 1998), lithology (Cía and Andrés, 2008;Robustelli et al, 2009) or DEM (Ventura et al, 2005).…”

Análise Temática e Conceitual de Mapas Geomorfológicos: A Transcrição Gráfica da Complexidade do Relevo

“…Na maioria dos mapas analisados a morfocronologia aparece de modo implícito, sendo necessário o conhecimento geomorfológico prévio para inferir relações temporais, o que torna a análise cronológica (ainda mais) subjetiva e imprecisa. Em 21% dos mapas a morfocronologia foi implicitamente vinculada à geologia, principalmente às unidades litológicas, o que pode causar interpretação dúbia acerca da idade das formações rochosas e das formas de relevo, como apresentado no mapa do Parque Nacional Lagonegrese, na Itália (GIANO, 2016), da Serra do Montejunto, em Portugal (FONSECA, 2011), e da Alta Ribagorza, na Espanha (CÍA; ANDRÉS, 2008).…”

Relationships between Organic Beef Production and Agro-Ecosystems in Mountain Areas: The Case of Catalan Pyrenees

“…Cerdanya is divided into High Cerdanya (the northern part, in France) and Low Cerdanya (the southern part, in Spain) with a total surface of 1806 km 2 (547 km 2 in Spain, corresponding to 1.7% of the total surface of Catalonia). The climate is influenced by the transition between the Atlantic climate, with humid influences in the western Pyrenean regions, and the continental Mediterranean climate of the eastern Pyrenees [38], and is classified as temperate oceanic (Cfb, according to the Köppen-Geiger climate classification). In Alta Ribagorҫa the average annual temperature is of 10.1 • C (maximum in June and July and minimum in January) and the average precipitation of 639 mm, in Cerdanya the average annual temperature is of 9.8 • C (maximum in July and minimum in February) and the average precipitation of 619 mm.…”
