Geological Map of Spain. Scale 1:50.000 - Sheet 859 - POZOBLANCO
收藏资源简介:
The sheet 859 (POZOBLANCO) of the National Geological Map (MAGNA), was made in 2013 and published in 1997 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.
西班牙地质调查局(Geological Survey of Spain)于1997年发布、2013年编制的国家地质图(MAGNA)第859幅(波索布兰科幅),比例尺为1:50000。本地质图展示了地表出露的物质(岩石与沉积物)的属性、空间分布特征,以及所绘不同制图单元间的几何关系。 地质填图单元是指具有共同时代范围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中进行表达。每一个填图单元以及各类地质构造均通过专属的图式符号在图中予以表示。将这些单元绘制于地形底图之上,可提供一定的三维空间信息,该信息可通过其他地质数据、地质剖面图、地层剖面、钻孔等资料进行补充完善。本图的图例为象形符号体系,用于展示不同填图单元的空间关系,包括时代序列、叠置关系、几何联系以及侧向相变等,同时还涵盖了该图幅在区域格架内的构造、水文地质与地质位置信息。 自1991年起,MAGNA国家地质图系列与同比例尺的地貌图一体化编制,不可分割。该图整合了地表所有地质相关信息,可为地貌形态提供结构化且精准的描述。其编制以地貌成因学与地貌年代学为依据,通过参考地质图图例所设计的表格/图例中收录的对应年代地层柱,将相关信息纳入图中。侵蚀与沉积成因的地貌形态,通过专属符号、色彩样式以及能够提供相关信息的地表沉积物或岩性地层单元要素在图中予以表示。 MAGNA系列的每一幅图幅均配有公开出版、经过整编且采用数字格式的说明报告。 该数字信息以Coverage格式与Shapefile格式(ESRI)存储,另有配套指南对该数字信息的物理结构与编码规则进行说明。
