Q_10K_CR298G_SD_FER_SUP

The Feature Class Q_10K_CR298G_SD_FER_SUP with Polygon geometry at the 1:10,000 scale represents the location and extension of railway areas with satin or bridge, viaduct, overpass. Derived from the database produced on a scale of 1:5,000 of the multiscale DBTI (Integrated Territorial Database), which provided for the adaptation and structuring, in relation to IntesaGIS standards, of the I and II lot of the CTRN and the subsequent update by means of the photogrammetric resumption of 2007. The geographical information was organised into hierarchical groups, following the model defined in the framework of the State-Regions Agreement on Geographical Information Systems.比例尺为1:10000的多边形几何要素类（Feature Class）Q_10K_CR298G_SD_FER_SUP，用于表示带有侧线、桥梁、高架桥及天桥的铁路区域的位置与范围。本数据集源自多尺度DBTI（综合领土数据库，Integrated Territorial Database）按1:5000比例尺生成的数据库，该数据库遵循IntesaGIS标准，完成了CTRN第一、二批数据的适配与结构化处理，并通过2007年摄影测量复测完成后续更新。地理信息按照国家与大区地理信息系统协定框架内定义的模型，被组织为层级分组。
