Landelijk Grondgebruiksbestand Nederland 2021 (LGN2021) : achtergronden, methodiek en validatie
LGN2021 is a grid database presenting the Dutch land use in 20218 at a spatial resolution of 5 m. The database has 51 land use classes, distinguishing the main agricultural crops, forest, water, nature and urban classes.LGN2021 is a continuation of the LGN 2018-2020 versions. However, next to the increase in land use classes from 48 to 51, the production method has also been modified. The production method of LGN2021 is as close as possible to Basiskaart Natuur en Landschap (BNL) (resolution 2.5 m, the same versions of the base files, the same derived files, class definitions are taken over as...

LGN2021 is a grid database presenting the Dutch land use in 20218 at a spatial resolution of 5 m. The database has 51 land use classes, distinguishing the main agricultural crops, forest, water, nature and urban classes.LGN2021 is a continuation of the LGN 2018-2020 versions. However, next to the increase in land use classes from 48 to 51, the production method has also been modified. The production method of LGN2021 is as close as possible to Basiskaart Natuur en Landschap (BNL) (resolution 2.5 m, the same versions of the base files, the same derived files, class definitions are taken over as much as possible and unambiguous recording of LGN classes based on Multi Reclass Tool (MRT)). The following files were used to create LGN2021: Top10NL (version November 2021), Basis Registration Parcels 2021 (BRP2021), Land use database 2015 (BBG2015), naturemanagement types from Information Model Nature 2021 (IMNa2021), terrain elevation database ofNetherlands (AHN3/4), satellite images (particularly Sentinel-2) and aerial photos from 2021. Every year a newLGN version is published that shows the land use of the previous reference year. The development of LGN2021took place on a commercial basis within the Applied Spatial Research team of Wageningen Environmental Research (WENR). The file is currently used by, among others, the WOT, the RIVM, the provinces and the waterboards. From 2023, the LGN file will be made available as Open Data. ; LGN2021 is een gridbestand dat het Nederlands landgebruik in 2021 met een ruimtelijke resolutie van 5 m weergeeft. Het bestand kent 51 landgebruiksklassen waarbij de belangrijkste landbouwgewassen, bos, water, natuur en stedelijke klassen worden onderscheiden. LGN2021 is een voortzetting van de LGN 2018-2020 versies. Echter, naast een toename van het aantal klassen van 48 naar 51 is ook de productiemethodiek aangepast. De productiemethode van LGN2021 sluit zoveel mogelijk aan bij Basiskaart Natuur en Landschap (BNL) (resolutie 2.5 m, dezelfde versies van de basisbestanden, zelfde afgeleide ...
