Landelijk Grondgebruik Nederland 2024 (LGN2024)

LGN2024 is a grid file that shows Dutch land use in 2024 with a spatial resolution of 5m. The legend consists of 51 land use classes and is comparable with LGN2021, LGN2022 and LGN2023. However, some LGN classes changed their definition slightly due to adaptations in the production methodology.<br>LGN2024 is distinguishing the main agricultural crops, forest, water, nature and urban classes. LGN2024 is a continuation of LGN2021, LGN2022 and LGN2023. For LGN2022 compared to LGN2021 some small modifications were made. The most important ones are: - Use of OSM and Top10NL for mapping solar parks- Introduction of small linear water elements- Subdivision of BNL class 200 'Overig grondgebruik' into 200, 220 'Basaltblokken en steenglooiingen and 230 'bebouwd gebied'- Introduction of MRT rules for new nature areas- New dataset 'Agrarisch Natuur- en Landschapsbeheer (ANLb 030 verantwoordingsaanvraag (versie februari 2023)' to define 'Natuurlijk beheerde agrarische graslanden'.- New way to produce the LGN classes 251, 252 and 252.<br>Next to these modifications applied for LGN2022 an additional small set of adaptations were made for LGN2023. The most important ones are:- Next to introduction of small linear water elements in LGN2022 (ditches), small water courses (0.5-3m) in swamp and salt marshes are taken up in LGN2023- Small corrections 'Hoogveen', 'Zoet/zout water' and 'Kwelder' masks- Small adaptations in the Multi Reclass Tool (MRT)- Skipping of postprocessing step for classes 251, 252 and 253 See also 'Factsheet productie LGN2023' for more details.<br>LGN2024 is comparable with the specifications of LGN2023. Main differences are a further improvement of the 'Kwelder' and 'Zoet/zout' masks and the recoding of BRP class 331 ("Grasland, natuurlijk. Met landbouwactiviteiten" naar LGN klasse 45 " Natuurlijk beheerde agrarische graslanden" in stead of LGN class 1 "Agrarisch gras" (LGN2022, LGN2023).<br>The following files were used to create LGN2024: Top10NL (version November 2024), Basis Registratie Percelen 2024 (BRP2024), Basiskaart Natuur en Landschap 2024 (BNL2024), Basisregistratie Adressen en Gebouwen (BAG February 2025), Nieuw Bestand BodemGebruik 2020 (NBBG2020 versie oktober 2024), Beheertypen IMNa (IMNa versie januari 2025), Agrarisch Natuur- en Landschapsbeheer (ANLb 030 verantwoordingsaanvraag 2024 (versie 12 november 2024)) and the Algemeen Hoogtemodel Nederland (AHN4/5). In addition satellite images (particularly Sentinel-2) and aerial photos from 2024 have been used in the classification of the nature area. <br>The dataset is public since July, 22nd 2025 which is made possible by WOT Natuur &amp; Milieu, Het Waterschapshuis, Interprovinciaal Overleg, RIVM and Wageningen Environmental Research.

LGN2024是一款网格文件，用于展示2024年荷兰土地利用现状，空间分辨率达5米。该数据集的图例包含51个土地利用类别，可与LGN2021、LGN2022及LGN2023系列兼容，但部分LGN类别因生产方法调整，定义出现小幅变更。<br>LGN2024区分了主要农作物、森林、水域、自然及城镇用地类别，是LGN2021、LGN2022与LGN2023的延续版本。相较于LGN2021，LGN2022实施了若干小幅修改，核心调整包括：<br>- 采用开放街道地图（OpenStreetMap, OSM）与Top10NL绘制太阳能园区分布<br>- 新增小型线性水体要素<br>- 将BNL类别200“其他土地利用”细分为200、220“玄武岩块与石矿场”及230“建成区域”<br>- 为新型自然区域引入多重分类工具（Multi Reclass Tool, MRT）规则<br>- 启用新数据集《农业自然与景观管理（ANLb 030核算申请，2023年2月版）》以定义“自然管理型农业草地”<br>- 调整了LGN类别251、252及252的生成方式<br>除上述针对LGN2022的修改外，LGN2023还进行了额外小幅优化，核心变更包括：<br>- 除LGN2022中新增的小型线性水体（沟渠）外，LGN2023进一步纳入沼泽与盐沼中的小型水道（0.5-3米宽）<br>- 对“高位泥炭地”“淡水/咸水”及“潮滩”掩膜进行小幅修正<br>- 对多重分类工具（MRT）进行小幅调整<br>- 跳过了类别251、252及253的后处理步骤。详细信息可参阅《LGN2023生产情况说明书》。<br>LGN2024与LGN2023的规范基本兼容，主要差异在于对“潮滩”与“淡水/咸水”掩膜的进一步优化，以及将BRP类别331（“天然草地，伴随农业活动”）重编码为LGN类别45“自然管理型农业草地”，而非此前LGN2022、LGN2023中归类至LGN类别1“农业草地”的处理方式。<br>LGN2024的制作用到了以下数据源：Top10NL（2024年11月版）、2024年地块基础登记（Basis Registratie Percelen 2024, BRP2024）、2024年自然与景观基础地图（Basiskaart Natuur en Landschap 2024, BNL2024）、地址与建筑基础登记（Basisregistratie Adressen en Gebouwen, BAG，2025年2月版）、2020年土地利用新文件（Nieuw Bestand BodemGebruik 2020, NBBG2020，2024年10月版）、IMNa管理类型（IMNa，2025年1月版）、农业自然与景观管理（ANLb 030核算申请2024，2024年11月12日版）及荷兰通用高程模型（Algemeen Hoogtemodel Nederland, AHN4/5）。此外，自然区域分类还用到了2024年的卫星影像（尤以Sentinel-2为主）与航空照片。<br>本数据集于2025年7月22日正式公开，其发布得到了WOT Natuur & Milieu、Het Waterschapshuis、省际协商委员会、荷兰国家公共卫生与环境研究所（RIVM）及瓦赫宁根环境研究所的支持。
