Hydrogeological map of Iška alluvial fan 1:25 000 ATOM services

Data of Geological map were reclassified into classes of IAH classification on the base of hydrogeological characteristics. IAH classification is based on description of the hydrogeological units. Firstly, based on extensiveness and productivity and secondly on type of porosity. The purpose is to provide assistance to the strategy of groundwater exploitation as to protection and water resources management.地质图数据依据水文地质特征，被重新划归至国际水文地质学家协会（IAH）分类体系的相应类别中。该分类体系以水文地质单元的描述为基础，首先依据其分布范围与产水能力，其次根据孔隙类型进行划分。本数据集旨在为地下水开采、保护及水资源管理的相关战略提供支撑。
