Slope Analysis/Reclassify from a DEM in QGIS 3 (in degrees/percentage)

Reclassification of a Slope/Raster in QGIS 3 1. At first load your DEM Raster to Qgis canvas/screen, 2. If your Input DEM Raster is on 'Degree/WGS_1984' then, Reproject your DEM Raster layer's EPSG from Geographic CRS 'Degree/WGS_1984' to Projected CRS 'Transverse_Mercator/WGS_1984_UTM_Zone_..N' #[Raster-Projections-Warp 'reproject'] 3. Now, goto Raster-Analysis-Slope, 4. On processing toolbox, type reclass and select 'Reclassify by table', 5. If you want to vectorize that classified slope then go to Raster-conversion-Raster to Vector To download Processing Algorithms (tools for automation): 1.
