Re: [GRASS-user] Need help in reprojecting raster images

Thank you all. It worked. However I noticed that the projected boundary values of N, S, W and E in GRASS are not same as the values obtained from projecting the same image in ENVI image processing software and in gdalwarp. Projection of the scene in Lambert Azimuthal Equal Area is similar (but

Re: [GRASS-user] Need help in reprojecting raster images

Hi, I tried the way you told. I created a new location in laea without setting the default boundary. Then from this mapset I used r.proj location*=input_location* mapset=*input_mapset* input=*input_raster name* output= *output_raster* I get an error: ERROR: Input raster map is outside current

Re: [GRASS-user] Need help in reprojecting raster images

Hi Uttam, if I understand your problem correctly, you can use the -p flag of r.proj to print input map's bounds in the current projection. With this information you can set the region boundaries appropriately using g.region. Afterwards you can 'import' your raster into your laea-projection

Re: [GRASS-user] Need help in reprojecting raster images

Hi Uttam, you may want to first do v.in.region in your input location, this creates a vector with the limits of your input location (set g.region to your raster of interest first), then v.proj the output of v.in.region in your target location, set region there with the imported vector and just

Re: [GRASS-user] Need help in reprojecting raster images

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 ,

[GRASS-user] Need help in reprojecting raster images

Hi All, I have a set of Landsat images in Sinusoidal Projection, WGS84 Datum. I know the north, south, east and west extent of the boundary of the image. I want to reproject the image to Lamberts Azimuthal Equal Area, WGS84 Datum. I do not know what will be the coordinates of the north, south,
