DTM 0.5x0.5m – RER 2023-24

Digital model of the field in grid format. The product represents the altimetry through a 0.5 m x 0.5 metre cell model to which the altitude information is associated. The model is derived from altimetric information obtained from LiDAR reliefs (plane) The acquisition of the images was carried out under conditions with limited foliation, minimal snow residues and inclination of solar rays not less than 25°; cartographic cut: 1000x1000meters. For more information, see the in-depth page https://geoportale.regione.emilia-romagna.it/approfondimenti/rer23_24 The extension of the areas already available and more information in the WMS service “metadata_raster”本数据集为格网格式野外测区数字模型。该产品通过0.5米×0.5米的格网单元关联高程信息，以此呈现地形高程数据。该模型的数据源为激光雷达（LiDAR）获取的平面地形高程测量信息。该数据集所用影像的采集条件为：植被叶层稀疏、积雪残留极少，且太阳高度角不低于25°；制图裁切范围为1000米×1000米。如需获取更多详细信息，请访问以下详情页面：https://geoportale.regione.emilia-romagna.it/approfondimenti/rer23_24。现有覆盖区域的扩展范围及更多相关信息，可通过Web地图服务（Web Map Service, WMS）"metadata_raster"查询获取。
