Greetings<div>I have an image without any GCP's but, teorethically it's in WGS84. I have all pixel positions outside that file. My question is, what should I do in GRASS to rectify/project this image? I thought in two solutions</div>
<div>1- import, using r.in.gdal in a XY projection and rectify. Is it possible to rectify a raster, with i.rectify, using a file outside GRASS (e.g. a text file?)</div><div>2- use GDAL to add GCP's points to file and then import to grass already rectified..</div>
<div><br></div><div>Which one is the best solution?</div><div>THank you</div><div><br></div><div>Nikos</div>
