Digital Elevation Model for Hydrography (MDEH) of 1m of the Autonomous Community of the Basque Country. Year 2008

The Digital Elevation Model for hydraulic studies is formed by the Digital Terrain Model plus the Elevation Model of buildings and constructions in which bridges are excluded. This MDEH is distributed in the ETRS89 geodetic reference system and orthometric dimensions, in .ASC format with 5000 mesh cut of the PNOA.水利研究用数字高程模型（Digital Elevation Model, DEM）由数字地形模型（Digital Terrain Model, DTM）叠加剔除桥梁后的建（构）筑物高程模型构建而成。该模型（MDEH）采用1989年欧洲大地参考系（ETRS89）与正高基准发布，数据格式为.ASC，基于西班牙国家航空正射影像计划（Plan Nacional de Ortophotografía Aérea, PNOA）的5000网格分幅生成。
