Geological Map of Spain. Scale 1:50.000 - Sheet 926 - MENGÍBAR
收藏资源简介:
The sheet 926 (MENGÍBAR) of the National Geological Map (MAGNA), was made in 1992 and published in 1994 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.
西班牙国家地质图(National Geological Map, MAGNA)的926号图幅(MENGÍBAR)由西班牙地质调查局(Geological Survey of Spain)于1992年编制,1994年正式发布,比例尺为1:50000。该地质图展示了地表出露物质(岩石与沉积物)的属性、空间分布特征,以及图面所绘各制图单元间的几何关联。 地质填图单元指具有共同年代区间的一种或多种岩性的集合体,以对应比例尺或既定分辨率在图上表达。各填图单元及各类地质构造均以专属符号在图中予以表示。将上述单元绘于地形底图之上,可提供一定的三维空间信息,该类信息可辅以其他地质数据、地质剖面、地层剖面及钻孔等资料进行完善。本图图例以象形图标形式,用以阐释各填图单元的空间关系,涵盖年代序列、叠置关系、几何关联、侧向相变等内容;同时还包含该图幅在区域地质框架内的构造、水文地质与地质位置信息。 自1991年起,MAGNA系列地质图与同比例尺地貌图实现一体化编制。该套图件涵盖地表全部地质内容,并可提供关于地表形态的结构化精准信息。其编制以地貌成因与地貌年代学为依据,采用源自配套地质图图例表格的对应年代地层柱,将相关内容纳入图件之中。各类侵蚀与沉积地貌形态均通过专属符号、色彩模式,以及能够提供相关信息的地表沉积物或岩性地层要素予以区分表达。 MAGNA系列的每一幅图幅均配有经编辑发布的数字化格式说明报告。 数字化信息以地理覆盖数据集(coverage)与Shapefile(ESRI格式)存储。另有配套指南对数字化信息的物理结构及其编码规则进行详细说明。
