Geological Map of Spain. Scale 1:50.000 - Sheet 533 - SAN LORENZO DEL ESCORIAL

The sheet 533 (SAN LORENZO DEL ESCORIAL) of the National Geological Map (MAGNA), was made in 1990 and published in 1993 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）第533幅（圣洛伦索-德埃斯科里亚尔，SAN LORENZO DEL ESCORIAL）由西班牙地质调查局于1990年编制、1993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，以及各制图单元间的几何关联关系。地质填图单元（geological mapping unit）指具有共同年代范围的一种或多种岩性的集合，在地图上以对应比例尺或限定分辨率进行标注表达。每个填图单元及各类地质构造均配有专属符号系统，用于在图件中实现可视化表达。将此类单元绘于地形底图之上，可获取一定的三维空间信息，该类信息可通过其他地质资料、地质剖面、地层柱状图、钻孔数据等进一步补充完善。本图的图例采用象形图示形式，用于呈现不同填图单元的各类空间关系，包括年代序列、叠置关系、几何关联、侧向相变等，同时还涵盖了区域地质框架内的构造信息、水文地质信息，以及该幅图件在区域中的地理位置。自1991年起，MAGNA系列国家地质图开始与同比例尺地貌图一体化编制。该系列图件涵盖了地表全部地质信息，可提供结构化且精准的地表形态数据。其编制基于地貌成因与地貌年代学体系，采用了借鉴地质图图例设计规范的表格/图例中所附的对应年代地层柱（chronostratigraphic column）。地图通过专属符号、色彩图案以及地表沉积物或岩性地层单元要素，对侵蚀地貌与沉积地貌形态进行差异化表达。针对MAGNA系列的每一幅图件，均配有正式出版、编辑并以数字格式留存的说明报告。该数据集的数字信息以Coverage（ESRI格式）与Shapefile（ESRI格式）存储，另有配套指南对数字信息的物理结构及其编码规则进行详细说明。
