Converting ArcGIS raster colormap file (*.clr) to QGIS style file …
WebAug 30, 2024 · You can use projectRaster () to resample to a new resolution (also extent and CRS): r2resampled <- projectRaster (r2,r1,method = 'ngb') r3resampled <- projectRaster (r3,r1,method = 'bilinear') The first one is categorical, so it's necessary to use nearest neighbor as method ( ngb ). WebThe style file might be for ARCGIS users. It is not in a human readable format. QGIS uses XML-files to store styling properties, so you have no luck with just renaming the extension.
