Does QGIS - through one of its rich algorithms library - allow for reduction of raster DSM/DEM resolution? I want to speed up the analyses and reduce effect of detailed raster on results readability.
The problem lies in the detail level of the raster. Input dsm was made based on the uav survey (output format: .tiff), so its size (area) is not large, but very, very detailed. This makes results of every analysis run on it difficult to view - i.e. QGIS calculates the aspect for every bump even 10 cm high, or streams for catchments for completely irrelevant areas.
