Cartografia Base Punt de Cota/Cota Points

It contains information about high points of the municipality of Valencia, including their coordinates X, Y, Z. Official vector cartographic series of reference at scale 1:500, 1:1000 and 1:2000 in 2D, elaborated by the Cartography Section of the Planning Service., which represents the topographical reality of the TM of Valencia. It is a combination of photogrammetric refunds from the August 2018 flight, 2006 flights and GNSS measurements. Geodetic Reference System ETRS89, UTM projection in spindle 30. Vertical datum: the altitudes refer to the average level of the Mediterranean Sea in Alicante. EPSG code: 25830. Planimetric accuracy 10-50 centimeters. The continuous cartographic base is structured for exploitation using Geographic Information Systems. The geographical phenomena that make up the series are structured in these 6 thematic units: orography, hydrography, constructions and buildings, transport networks and toponymy. All of them contain the following fields: Creation: creation method (photogrammetric restoration, GNSS measurement, orthophoto digitisation), date of creation (flight date or date of data collection), scale (information generation scale).The data model of the BCV05 of the ICV was followed. The phenomena have been represented following the catalogue of phenomena of the CV05 series. In the case of elements not covered by the BCV05 model, it has been expanded by generating a data model for larger scales that can be requested at [e-mail].本数据集包含巴伦西亚市（Valencia）境内制高点的相关信息，涵盖其X、Y、Z三维坐标。 由规划服务处制图科编制的官方2D矢量参考制图系列，比例尺覆盖1:500、1:1000与1:2000，精准呈现巴伦西亚市政辖区的地形实况。该数据集整合了2018年8月飞行作业、2006年飞行作业的摄影测量数据与全球导航卫星系统（GNSS）测量成果。 采用欧洲大地参考系统（ETRS89），使用30号分带的通用横轴墨卡托（UTM）投影。垂直基准面：高程参照阿利坎特（Alicante）海域地中海平均海平面。EPSG编码为25830。平面精度为10至50厘米。 本连续制图基准面向地理信息系统（GIS）的开发应用进行了结构化设计。构成该系列的地理要素分为以下6个专题单元：地貌、水文、建筑与构筑物、交通网络以及地名。 所有专题单元均包含以下字段：创建信息：创建方式（摄影测量修复、GNSS测量、正射影像数字化）、创建日期（飞行作业日期或数据采集日期）、比例尺（信息生成比例尺）。 本数据集遵循瓦伦西亚自治区制图与地质研究所（ICV）的BCV05数据模型，要素的符号表达严格遵循CV05系列的要素分类目录规范。 针对BCV05模型未涵盖的要素，本数据集已通过构建适用于更大比例尺的数据模型进行扩展，相关需求可通过邮箱[e-mail]提交。
