The LGN6 file is a nationwide raster file with a resolution of 25 meters in which 39 forms of land use are distinguished. The file distinguishes the most important agricultural crops, a number of nature classes and urban classes. The LGN6 file has undergone some important changes compared to LGN5. The geometry and thematics on main classes are now completely based on Top10vector (version 2006). Agricultural plots, greenhouses, orchards, fruit farms, tree nurseries, sand, heathland, forests, water and infrastructure have been taken over from Top10vector. The urban area is defined by means of the Boundary Built Area (BG2003) and Soil Use File (BBG) files. For the further interpretation of the main classes, satellite images from 2007 and 2008, aerial photos, Basismap Nature 2007 (BKN2007) and LGN5 were used, among other things. The definitions of the land use classes have been tightened. Land use files LGN1 and LGN2 were still experimental files with limited accuracy and obvious shortcomings. In LGN3 these shortcomings have been largely resolved and with LGN3plus the usability of the file for nature and ecology applications has been greatly improved. With the LGN4 file, a new step has been taken in expanding the application possibilities of the LGN file. Important improvements that have been made to the LGN4 file are a link of the agricultural crops to the TOP10 vector and the possibility to trace changes in land use that occurred in the period 1995-2000. Versions 1-3 of the LGN file were delivered as a single raster file. The LGN6 file, like the LGN4 and LGN5 file, does not consist of a single raster file, but is a collection of files.
