forest area #44
Die Waldfläche ist die Gesamtheit aller Flächen, die gemäss Walddefinition des LFI als Wald bezeichnet werden. Die Walddefinition schliesst Gebüschwald mit ein. Diese Zielgrösse (Thema) wird auch verwendet für Auswertungen der Gesamtfläche, wenn es um die Unterscheidung von Wald und Nichtwald geht.
protection forest perimeter SilvaProtect #1773
Lage der Probefläche innerhalb oder ausserhalb des SilvaProtect-Schutzwaldperimeters. Der Perimeter wurde vom BAFU als GIS-Daten zur Verfügung gestellt und stammt aus dem Projekt SilvaProtectCH des BAFU.
degree of transportation system density by method of timber harvest #2273
Erschliessungsgrad basierend auf der Schrägdistanz zur nächsten Strasse (ab 3 m Breite und Befahrbarkeit für 4-achsige Fahrzeuge mit Gesamtgewicht von mind. 28-32 t) und Holzernteverfahren.
economic region #366
Die Wirtschaftsregionen bilden eine Unterteilung der forstlichen Produktionsregionen nach wirtschaftlichen und geographischen Gesichtspunkten. Sie wurden erstellt durch das damalige Bundesamt für Forstwesen für die forstliche Statistik, lange vor dem ersten LFI (1983-85). Die Regionenzugehörigkeit wurde definiert über die damaligen Gemeindegrenzen nach unbekannten Kriterien. Das LFI arbeitet sei jeher mit diesen unveränderten Perimetern mit einer winzigen kleinen Ausnahme am Genfersee.
accessible forest without shrub forest #434
Zugehörigkeit zum zugänglichen Wald ohne Gebüschwald. Unter der jeweiligen Inventurnummer gehören jene Punkte des terrestrischen Netzes zum "zugänglichen Wald ohne Gebüschwald", welche terrestrisch begehbar waren und dem "Wald ohne Gebüschwald" zugeordnet wurden. Im internationalen Reporting werden diese als "forest available for wood supply" ausgewiesen.
1.4 x 1.4 km grid #410
Zugehörigkeit zum geometrischen 1.4 x 1.4 km Netz des LFI (auch Basisnetz). Das 1.4 x 1.4 km Netz ist das Netz, das alle LFI-Inventuren gemeinsam haben. Das 1.4 x 1.4 km Netz entspricht somit dem gemeinsamen terrestrischen Netz der Inventuren LFI1, LFI2, LFI3, LFI4 und LFI5.
