Cartography quadricula base/frame 2000

Grid 1000 and 2000 of the municipality of Valencia. 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].瓦伦西亚直辖市1:1000与1:2000比例尺矢量格网数据集。 本数据集为官方参考级2D矢量制图系列，比例尺涵盖1:500、1:1000与1:2000，由规划服务局制图科编制，完整呈现瓦伦西亚市辖领土的地形现状。数据集整合了2018年8月航摄、2006年航摄的摄影测量解译成果以及全球导航卫星系统（GNSS）测量数据。其采用的大地参考系为ETRS89，通用横轴墨卡托（UTM）投影第30分带；垂直基准面以西班牙阿利坎特海域地中海平均海平面为准，EPSG代码为25830，平面精度为10至50厘米。该连续式制图基础架构专为地理信息系统（GIS）的开发与应用进行结构化设计。 构成本系列的地理要素划分为以下6个主题单元：地貌学、水文地理学、建筑与构筑物、交通网络及地名学。所有要素均包含以下字段：制作方式（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）、比例尺（信息生成比例尺）。 本数据集遵循瓦伦西亚制图研究所（ICV）的BCV05数据模型，并依据CV05系列的要素编目规范进行要素表达。针对BCV05模型未覆盖的要素，已通过构建适配大比例尺的数据模型进行扩展，相关扩展数据可通过[e-mail]申请获取。
