This dataset comprises a series of high-resolution geospatial raster layers representing the environmental factors used to model soil-erosion susceptibility in High-Arctic watersheds, along with the resulting model outputs. The rasters include K (soil), C (vegetation), LS (topography), R (precipitation), I (ice content) factors derived from remote-sensing data and GIS-based processing steps described in the associated article. All rasters are georeferenced (in EPSG:2957 - NAD83(CSRS) / UTM zone 13N) and harmonized to a common projection and resolution. These layers offer a reproducible basis for erosion modelling and enable further geospatial analyses of landscape sensitivity in Arctic environments.
