Regional environmental monitoring: Mapping of vegetation on open marshes in Dalarna and Gävleborg, 1999. Myrvegetation type map.

“Satellite-based monitoring of wetlands” is used to detect land use-related vegetation changes in open marshes. The method is based on the assumption that spectral and vegetation homogeneous ants appear similar in terms of phenology and weather. The “Satellite-based monitoring of wetlands” performs a basic classification of open ant in the older satellite scene. The base classification distinguishes spectrally homogeneous wetland units that form the basis for the targeted change analysis carried out in the next step. The basic classification is actually a by-product used for the targeted change analysis, but it has a value in itself because it is a comprehensive mapping of ant vegetation within the mask for open ant. The study “Kartering of vegetation on open marshes in Dalarna and Gävleborg — Myrvegetation type map” aims to develop an ant vegetation type map for open ant by translating the basic wetland units (via a translation table) into well-known hydrological vegetation types.「基于卫星的湿地监测（Satellite-based monitoring of wetlands）」用于检测开阔沼泽中与土地利用相关的植被变化。该方法基于如下假设：光谱与植被均一的区域在物候与气象条件上表现相似。「基于卫星的湿地监测」可对历史卫星影像中的开阔区域开展基础分类，该分类可区分出光谱均一的湿地单元，这些单元将作为下一步针对性变化分析的核心依据。实际上，该基础分类是为针对性变化分析服务的副产品，但其本身具备独立价值——可对开阔区域掩膜内的湿地植被开展全面制图。 「达拉纳与耶夫勒堡地区开阔沼泽植被制图——沼泽植被类型图（Kartering of vegetation on open marshes in Dalarna and Gävleborg — Myrvegetation type map）」这项研究，旨在通过转换表将基础湿地单元转换为公认的水文植被类型，进而构建针对开阔区域的沼泽植被类型图。
