Offshore Sand Information System (In_Sand) - Area

It contains the polygons that represent the areas in which the sandy deposits have been identified and for which intervention concessions have been requested. The name of the area (Name_A) is specified, with an identifier for each Region (e.g. RER_A, Emilia-Romagna_A Region), the concession (data currently not available) and the sheet, with reference to the numbering of the geological cartography of the Italian seas (CARG project at 1:250,000 scale) in which these areas are included. The areas were named keeping the letters that had been chosen during the first geophysical and geognostic research campaigns i.e. area:RER_A, RER_B, RER_C, RER_H, RER_I.本数据集包含表征已探明砂质沉积分布区域的多边形要素，此类区域均已提交作业许可申请。数据集标注了各区域的名称（Name_A），并为每个区域配备专属标识符（例如RER_A、艾米利亚-罗马涅大区_A [Emilia-Romagna_A Region]）；同时记录了许可相关信息（当前数据暂未提供）以及图幅编号，该编号对应包含此类区域的意大利海域1:25万比例尺CARG地质制图项目的编号规则。此类区域的命名沿用了首次地球物理与地质勘查作业中选定的字母标识，具体包括：RER_A、RER_B、RER_C、RER_H、RER_I。
