CR17G_BREAKLINE

The Feature Class CR17G_BREAKLINE geometry Line belongs to the Orography layer to the theme Altimetry. 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.要素类（Feature Class）CR17G_BREAKLINE的几何类型为线要素（Line），隶属于高程主题（Altimetry）下的地形图层（Orography layer）。该数据集源自多尺度DBTI（综合领土数据库，Integrated Territorial Database）中按1:5000比例尺生成的成果数据库，该数据库依据IntesaGIS标准完成了CTRN第一、二期数据的适配与结构化处理，并通过2007年摄影测量复测开展后续更新工作。地理信息按照国家-大区地理信息系统框架协议中定义的模型，被组织为层级化分组。
