Geological Map of Spain. Scale 1:50.000 - Sheet 1036 - OLVERA

The sheet 1036 (OLVERA) of the National Geological Map (MAGNA), was made in 1990 and published in 1995 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.西班牙地质调查局于1990年编制、1995年发布了国家地质图（National Geological Map, MAGNA）的第1036幅图件（OLVERA）。该图件比例尺为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，以及所绘各类制图单元间的几何关系。 地质填图单元是指具有共同年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件中呈现。每个填图单元及各类地质构造，均通过专属的符号体系在图上进行表达。将这些单元绘制在地形底图上，可提供一定的三维空间信息，该类信息可通过其他地质数据、地质剖面、地层剖面、取样点等予以补充完善。本图的图例以图示方式展示了各类填图单元的空间关系，包括年代序列、叠置关系、几何联系、侧向相变化等。此外，图例还涵盖了区域框架内该图幅的构造、水文地质及地质位置信息。 自1991年起，MAGNA国家地质图系列与同比例尺的地貌图已密不可分地结合编制。该系列图件涵盖了地表地质的全部内容，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，并参考地质图的表格/图例设置，纳入了对应的年代地层柱。图中通过专属符号、色彩模式以及可提供相关信息的地表沉积物或岩性地层单元，对侵蚀与沉积两类地貌形态进行个性化表达。 针对MAGNA系列的每一幅图件，均配有正式出版、编辑完成的数字化说明报告。 数字化信息以覆盖数据集（coverage）与Shape格式（ESRI）存储。另有一份指南对数字化信息的物理结构及其编码规则进行说明。
