Cartography Base Communication/Communications

It contains information on the communication routes of the municipality of Valencia, including its method of creation, date and type of route. 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直辖市的交通线路相关信息，涵盖线路的制作方法、生成日期与线路类型。 本数据集包含由规划服务局制图科编制的1:500、1:1000及1:2000比例尺二维官方参考矢量制图系列，该系列完整呈现瓦伦西亚TM（TM of Valencia）的地形地貌实况。该数据集整合了2018年8月航测、2006年航测的摄影测量修复成果以及全球导航卫星系统（Global Navigation Satellite System, GNSS）测量数据。采用大地参考系统ETRS89，UTM投影分带30。垂直基准面：高程参照阿利坎特海域地中海平均海平面。EPSG代码为25830。平面精度为10至50厘米。该连续制图基底专为地理信息系统（Geographic Information System, GIS）的开发应用而构建。 组成该系列的地理要素被划分为以下6个专题单元：地貌、水文、建筑与设施、交通网络以及地名学。所有专题单元均包含以下属性字段：制作方式（含摄影测量修复、GNSS测量、正射影像数字化）、制作日期（航摄日期或数据采集日期）以及比例尺（信息生成比例尺）。 本数据集遵循ICV的BCV05数据模型，地理要素的符号表达遵循CV05系列要素目录规范。针对BCV05模型未覆盖的要素，本数据集通过生成适配大比例尺的扩展数据模型进行补充，相关数据模型可通过[e-mail]邮箱申请获取。
