This dataset maps forest damage areas in Upper Lapland caused by the autumnal moth (tunturimittari), a geometrid moth species known for periodic outbreaks defoliating birch forests. Damage from the early 2000s was identified by interpreting NDVI difference images derived from Landsat and Sentinel-2 satellite imagery, combined with laser-scanned (LiDAR) data on tree height and canopy cover. Results were validated against aerial photographs and field observations. Damage areas from a 1960s outbreak were also delineated, likely using historical aerial photography or archival survey records, allowing comparison of moth-caused forest damage extent across different decades in the region.”Tunturimittarin 2000-luvun alussa aiheuttamia tuhoalueita on tulkittu Landsat- ja Sentinel-2:n NDVI-erotuskuvien ja laserkeilatun puuston pituus/latvuspeitto-aineistojen avulla. Lopputulosta on verrattu ilmakuviin ja maastohavaintoihin. Tunturimittarin 1960-luvulla aiheuttamia tuhoalueita poimitt...
