Seaweed in the Schleswig-Holstein Wadden Sea 2004-08-25

Aircraft mapping of seagrass meadows since 1991 as part of the Trilateral Monitoring Programme (TMAP). 2 density classes of closed stocks are recorded. The identification of the surfaces from the sports aircraft is only possible from about 25% coverage, Zostera noltii and Z. marina are not distinguished. The results are entered in maps according to the observations, and the positional inaccuracies are greater for remote stocks. Similar, but differing, mappings from 1989 and 1990 are available in the context of ecosystem research in Schleswig-Holstein's Wadden Sea.本数据集为1991年起作为三边监测计划（Trilateral Monitoring Programme, TMAP）组成部分开展的海草床航空器测绘成果。数据集记录了2类郁闭海草群落的密度等级。采用小型航空器开展的海草床分布区域识别仅在覆盖度约25%及以上时方可实现，且未区分矮大叶藻（Zostera noltii）与大叶藻（Zostera marina）。测绘结果依据实地观测记录标注于地图中，偏远海草群落的位置误差相对更大。1989年与1990年的同类（存在细节差异）测绘成果可在石勒苏益格-荷尔斯泰因州瓦登海的生态系统研究项目中获取。
