Continous, multi-scale slope measurements in a terrain derived stream network for Fenoscandia (Norway, Sweden, Finland)

A continous, multiscale stream steepness raster dataset produced for the INVAFISH project (Norges forskningsråd 243910) with the following script: connectivity.py

It covers Norway, Sweden and Finland. The stream network has been derived with the GRASS GIS r.stream.extract module from a 10m digital elevation model (DEM). Slope has been calculated with r.slope.direction module at 10, 30, 50, 70, 110, and 150 m steps following the direction of the stream network.

Resolution of the raster data follows the pixels of the underlying 10m DEM. Raster values represent slope in degree * 100, so for example a value of 732  refers to 7.32 degree in slope. Negative slope values indicated artifacts in the underlying DEM and occure where the r.stream.extract module had to hydrologically enforce overland flow through pits or over ridges.

Data format is LZW-compressed GeoTiff in EPSG: 25833 coordinate system.
