Hi Monica, It should be straightforward using rgdal. Gtiff output is default, resolution is preserved by default, GDAL supports nitf (didn't test this) and geotiff supports x resolution and y resolution separately (x and y resolution may differ, but are constant for the image). So I expect the following snippet to work (if it doesn't, show us what goes wrong):
require('rgdal') GDALinfo('yourfile') # look at res.x and res.y imagery <- readGDAL('yourfile') writeGDAL(imagery, 'destinationfile') GDALinfo('destinationfile') Hope this helps, Arien On Tue, May 19, 2009 20:24, Monica Pisica wrote: > > Hi, > > I have some NITF (in lat long) files and i would like to save them as > geotif.
