Dear Micha and Hamish<br>Thanks for your solution and explanation regarding to raster import. Still i am confusing with rgb file. There are three rgb files that created first then when using i.rectify, another three rgb come with given extension. That make in total 6 files. Then r.composite as another colored image. I wish to use this color contour map just for digitizing. So can i delete all 6 rgb files. I tried to delete three rgb files after compositing. but there is a problem for rectifying. So i had to import again those deleted rgb files. And for rectifying it took half an hour for completion. That's why i asked this question.<br>
Thanks very much.<br clear="all"><br>-- <br>-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-<br>U Kyaw Moe Aung, Staff Officer<br>Planning & Statistics Division, Forest Department, Director General's Office<br>Nay Pyi Taw, Ph:095-67-405016, Fax: 095-67-405016<br>
