The sheet 119 (NOYA) of the National Geological Map (MAGNA), was made in 1981 and published in 2007 by the Geological Survey of Spain. It is distributed at scale 50000. The geological map shows the nature of materials (rocks and sediments) that appear on the surface, their spatial distribution and geometric relationships between the different cartographic units represented. A geological mapping unit is the grouping of one or more lithologies with common age range, which is represented on the map at a scale or defined resolution. Each mapping unit, and the different geological structures, is represented on the map with a symbolism itself. The representation of these units on the topographic base map provides some three-dimensional information that is completed with other geological data and geological sections, stratigraphic profiles, polls, etc. The map legend is a pictogram representing the spatial relationship of the different mapping units (chronology, overlapping, geometric relationship, lateral facies changes, etc.). It also includes structural, hydrogeological and geological location of the sheet within the regional schemes. Since 1991, the Geological Map Series MAGNA is made inseparably with the geomorphological map on the same scale. This map incorporates everything on the surface geology and provides a structured and accurate information of the land forms. It is organized on the basis of morphogenesis and morphocronology incorporated the map using the corresponding chronostratigraphic column included in a table / legend inspired by the geological map. The forms, erosional and depositional, are represented on the map by individualized by symbols and patterns of color and surface deposits or lithological formations elements that provide information. For each sheet of the series MAGNA there is an explanatory report published, edited and in digital format. The digital information is stored in coverage and Shape format (ESRI). There is a guide that describes the physical structure of the digital information and its codification.

MAGNA Sheet 119 information in the Spanish Geological Survey maps page
- Geologic maps are tools portraying interpretive, three-dimensional views of rock, sediment, and soil units that depict their distribution and age relationships. Geologic maps provide a context for testing scientific theories, hypotheses, and models. Geologic maps and their subsequent derivative products have immense economic and societal value, and when these maps are current, digital, and Internet accessible, they are particularly useful. They support our ability to locate and develop mineral and water resources; assess and protect groundwater quality; safely site solid and hazardous waste disposal facilities; construct, restore, maintain, and protect sensitive ecosystems; and identify and prepare for such natural hazards as earthquakes, volcanic eruptions, landslides, and land subsidence. Geologic maps can also show how the physical environment has been impacted by human activity. Geologic maps enhance our ability to identify health hazards; to site and build the nation’s infrastructure of roads and highways, railroads, pipelines, utilities, dams and locks, buildings, and foundations; and to make more informed land-use and planning decisions. Geologic maps are fundamental elements for informing the policy decisions of federal, state, and local agencies.
Map viewer for page 119
- The Geoscientific Map viewer shows all the spatial information available through map services. It also allows to query the attributes and other related information to each entity (cards, images, reports, metadata, etc.).
ArcGIS Online web map
- Interactive map that displays geographic information. These maps support visualization, editing, analysis, and time. Maps are the basis of apps and can be viewed on a wide variety of clients, including mobile devices, desktop applications, and web browsers.
Web Map Service (WMS) for MAGNA series
- A Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the Internet that are generated by a map server using data from a GIS database. The specification was developed and first published by the Open Geospatial Consortium in 1999.
ArcGIS Server service for MAGNA series
- An ArcGIS Server web service represents a GIS resource?such as a map, locator, or image?that is located on an ArcGIS Server site and is made available to client applications.
Google Earth service (KML) for MAGNA series
- KML is a file format used to display geographic data in an Earth browser such as Google Earth, Google Maps, and Google Maps for mobile. KML uses a tag-based structure with nested elements and attributes and is based on the XML standard.
The Geological Map of Spain (MAGNA) 1: 50,000 scale (including geomorphological map) is part of the infrastructure of geoscientific knowledge for socio-economic development. Supports activities such as hydro-geological and mineral resources, public works, agriculture, land use, the environment territorial planning, natural hazards and generally any action on the physical environment that supports the decision-making actions on the territory.
The realization of this geological cartography is based on the geological information from the incomplete Geological Map of Spain scale 1: 50,000 (first series). In addition it collects and analyzes other information concerning the area and its environment, including bases and other topographic mapping and related work as singular projects, doctoral dissertations, etc. The next step is the collection of data and samples for later study. After the transfer of field work to map, photo-interpretation work supported, and the final composition of the geological map. This cartography is completed with the elaboration of the text of memory and organization and classification of additional information. The digitization of the geological mapping information and normalization is in accordance with the Rules of digitization and Normalization defined by the IGME. Supervision, correction and validation also follow the procedure of digital mapping Review Institute. It consists of automatic controls error detection and correction, and thorough visual checks. Finally cartographic composition and symbolized files (.lyr) in ArcGIS is performed.
