Land occupancy: 2003, 2012, 2015, 2018 and 2021 in the territory of the Greater Narbonne Community of Agglomeration and the Narbonnaise Regional Natural Park in the Mediterranean

Five vintages representing land use in 2003, 2012, 2015, 2018 and 2021. Note: the data dictionary evolved slightly between 2003-2012 and 2015-2018. This trend is mainly related to the wasteland area, which has been declined into shrub and herbaceous wasteland from 2015. In general, it is recommended to properly appropriate the dictionary of definitions of 73 positions and associated UMC (Minimum Collection Unit). This dictionary is systematically integrated into the download of zipped folders.本数据集涵盖5个年份的土地利用数据，分别对应2003年、2012年、2015年、2018年及2021年。 注：2003-2012年与2015-2018年两个时段的数据字典存在细微差异。该差异主要涉及荒地用地类别：自2015年起，原荒地分类被细化为灌丛荒地与草本荒地。 总体而言，建议合理适配包含73个定义条目及配套UMC（Minimum Collection Unit，最小采集单元）的定义字典。该定义字典已完整集成于压缩包下载资源中。
