The CORINE Land Cover dataset for Norway for the reference year 2018 (CLC2018) was compared to detailed national land cover and land use data. This allowed us to describe the thematic composition of the CLC-polygons and aggregate the information into statistical profiles for each CLC-class. We compared the results to the class definitions found in the CLC mapping instructions, while considering the generalization and minimal mapping units required for CLC. The study showed that CLC2018 in general complied with the definitions. Nonconformities were mainly found for detailed and (in a Norwegian context) marginal classes. The classification can still be improved by complementing visual interpretation with classification based on the statistical profile of each polygon when detailed land use and land cover information is available. The use of auxiliary information at the polygon level can thus provide a better, thematically more accurate CLC dataset for use in European land monitoring.

挪威CORINE土地覆盖数据集的内容和准确性

将挪威2018基准年(CLC2018)的CORINE土地覆盖数据集与详细的国家土地覆盖和土地利用数据进行了比较。这使我们能够描述CLC多边形的主题组成,并将信息汇总到每个CLC类的统计资料中。我们将结果与CLC映射指令中的类定义进行了比较,同时考虑了CLC所需的通用性和最小映射单元。研究表明,CLC2018总体上符合定义。不合格主要是针对详细和(在挪威的情况下)边际等级中发现的。当可以获得详细的土地利用和土地覆盖信息时,仍可以通过基于每个多边形的统计轮廓对视觉解释进行分类补充来改进分类。
