描述.The Swiss National Forest Inventory (NFI) is a forest survey on national level which started in 1982 and has already reached its 5th survey cycle (NFI5). It can be characterized as a multisource and multipurpose inventory where information is mainly collected from terrestrial field surveys using permanent sample plots. In addition, data from aerial photography, GIS and forest service questionnaires are also included..The NFI‘s main objective is to provide statistically reliable and sound figures to stakeholders such as politicians, researchers, ecologists, forest service, timber industry, national and international organizations as well as to international projects such as the Forest Resources Assessment of the United Nations. For Switzerland, NFI results are typically reported on national and regional level..State of the art methods are applied in all fields of data collection which have been proven to be of international interest and have even served as a basis for other European NFIs.

Variables on the Sample Plot Captured by the Stereo GIS ApplicationGuided by the Stereo GIS Application, different measurements are carried out in the aerial stereo-images in order to determine a ‘forest/non-forest’ decision. The measurements try to make the forest decision as reproducible as possible. In addition to these measurements, expert interpretations are also carried out.

Field Assessmentned 7455 sample plots, of which 6357 were accessible and classified as ‘forest’ or ‘shrub forest’. On each forest or shrub-forest sample plot, around 280 different attributes were assessed. The individual work steps for assessing a sample plot as well as the equipment and tools used, are explained in detail.
