Opening the dataset
Display the image without projection
Reprojecting to epsg 4326, using rioxarray.reproject
Exporting to geotiff
Exporting without colormap
Exporting with RGBA colormap
Reprojecting to pre-defined grid
Mapping a raster onto original xsar grid
Raster masks from vector masks
Mask sigma0 over land
Adding masks
Convert a mask to dataset coordinates
