Landelijk Grondgebruik Nederland 2018 (LGN2018)

LGN2018 is a grid file that shows Dutch land use in 2018 with a spatial resolution of 5m. The legendconsists of 48 land use classes, distinguishing the main agricultural crops, forest, water, nature andurban classes. In addition to increasing the spatial detail (from 25*25m to 5*5m), the thematic detail ofespecially the nature areas has been greatly improved by, among other things, the use of multi-temporalSentinel-2 images and the AHN2/3 dataset. In addition to the Sentinel-2 images and the AHN2/3 dataset, thefollowing datasets were used to make LGN2018: Top10NL (version November 2018), Basis RegistratiePercelen 2018 (BRP2018), Bestand BodemGebruik 2015 (BBG2015), BasisKaart Natuur 2017 (BKN2017), and LGN7.In addition, aerial photos from 2018 have been used.<br>The dataset is public which is made possible by WOT Natuur &amp; Milieu, Het Waterschapshuis, InterprovinciaalOverleg, RIVM and Wageningen Environmental Research.LGN2018是一款栅格数据集（grid file），用于展示2018年荷兰土地利用状况，空间分辨率达5米。其配套图例包含48个土地利用类别，可区分主要农作物、林地、水域、自然用地及城市用地类型。相较于此前25×25米的空间分辨率，本次数据不仅提升了空间细节精度，更通过多时序Sentinel-2（哨兵二号）影像与AHN2/3数据集等技术手段，大幅优化了自然区域的专题细节表现。除Sentinel-2影像与AHN2/3数据集外，构建LGN2018还用到了以下数据集：2018年11月版Top10NL、Basis Registratie Percelen 2018（BRP2018）、Bestand BodemGebruik 2015（BBG2015）、BasisKaart Natuur 2017（BKN2017）以及LGN7。此外，本次研究还使用了2018年的航空摄影影像。本数据集可公开获取，此项公开工作得到了WOT Natuur & Milieu、Het Waterschapshuis、省际协调委员会（Interprovinciaal Overleg）、荷兰国家公共卫生与环境研究所（RIVM）以及瓦赫宁根环境研究院的支持。
