DTM 0,5x0,5m - RER 2022

Digital model of the terrain in grid format. The product represents altimetry through a cell model of 0.5 meters x 0.5 meters to which the altitude information is associated. The model is derived from altimetric information obtained from LiDAR (aeroplane) surveys carried out in the period February-May 2022 and January 2023, so as to obtain ground data in a situation with reduced foliage; cartographic cut 1000x1000 meters. Territory concerned: Enza river basin (portion), Apennine ridge in the provinces of Bologna and Modena, area of Parco Vena del Gesso Romagnola, capitals of Imola and Faenza, area of the 9 municipalities of Valmarecchia entered the Emilia-Romagna Region in 2009 and 2021, coast (and portion of hinterland) of Ferrara. The extension of the surveyed areas and further information can be found in the WMS service \"metadata_raster\"网格格式地形数字模型。本产品通过0.5米×0.5米的格网单元模型承载高程信息，实现地形高程表达。该模型的数据源自2022年2月至5月、2023年1月开展的机载激光雷达（LiDAR）测量获取的高程信息，以获取植被覆盖度较低状态下的地表数据；制图裁切单元为1000米×1000米。涉及覆盖区域包括：恩扎河流域（部分区段）、博洛尼亚省与摩德纳省境内的亚平宁山脊、罗马涅石膏灰岩公园（Parco Vena del Gesso Romagnola）区域、伊莫拉与法恩扎中心城区、2009年及2021年并入艾米利亚-罗马涅大区的瓦尔马雷基亚9个市镇所辖范围，以及费拉拉海岸（及部分内陆区域）。调查区域范围及更多详细信息可通过WMS服务"metadata_raster"查询获取。
