georeferencing image from scratch

Hi Marcelo,

I don't see anything in raster or rgdal that would do that directly.
However, this can be done I believe using gdal_translate / gdal_edit (for
adding the GCPs to the dataset) + gdalwarp (for warping). Both
gdal_translate and gdalwarp utilities have wrappers in the gdalUtils
package.

Cheers,
Lo?c Dutrieux

Hi all

I want to change a MSS landsat image which has bad georeferencing.

I have a grid of points with correct georeferences and want to use them
to reproject the image to a correct reference system.

Is there some way to this in R using "raster" or other package?

in idrisi I used to resample the image using a correspondence file
(.cor) with xold yold xnew ynew values.

I wonder if there is something similar I can do in R? Thanks in advance
