Hi Uttam If I understand you correctly you want to reproject a landsat image from sinusoidal to laea projection!! You dont have to manually set the bounding box while reprojecting a raster, as GRASS will take care of it.
First you create a new location and mapset with desired output projection , which in this case is Lamberts Azimuthal Equal Area. Then get into this mapset, use the following r.proj command. r.proj location*=input_location* mapset=*input_mapset* input=*input_raster name* output= *output_raster* More details here: https://grass.osgeo.org/grass70/manuals/r.proj.html If you then need to set your working area to a particular bounding box, use g.region g.region raster=*output_raster* regards Sajid On Tue, Sep 22, 2015 at 11:07 PM, Uttam Sinha <[email protected]> wrote: > > > Hi All, > > I have a set of Landsat images in Sinusoidal Projection, WGS84 Datum.
