Cartography Base Edificis/Buildings

It contains information about the facade of the buildings of each block of the municipality of Valencia, including their method of creation and date. 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].本数据集包含瓦伦西亚市各街区建筑外立面的相关信息，涵盖其制作方式与生成日期。 本数据集为瓦伦西亚市规划服务局制图科编制的官方参考矢量制图系列，包含比例尺1:500、1:1000及1:2000的二维产品，精准呈现瓦伦西亚市政管辖区域（TM of Valencia）的地形现状。该数据集的数据整合了2018年8月航摄、2006年航摄的摄影测量复原成果以及全球导航卫星系统（GNSS）测量数据。其采用大地参考系统ETRS89，UTM投影30分带；垂直基准面采用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。 该连续制图基底可依托地理信息系统（GIS）开展开发应用。 构成该制图系列的地理要素分为以下6大主题单元：地形地貌、水文水系、建构筑物、交通网络以及地名要素。 所有主题单元均包含以下信息项：制作信息：制作方式（含摄影测量复原、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）、信息生成比例尺。 本次制图遵循瓦伦西亚规划局ICV的BCV05数据模型，并采用CV05系列的要素分类目录进行要素表达。 对于BCV05模型未覆盖的要素，本数据集通过构建适配更大比例尺的数据模型进行了扩展，相关扩展模型可通过邮箱[e-mail]申请获取。
